Grip to body fitment question

I'm the one who started that other thread Battery grip D-BG6 issue.

I think the gap seems to be normal with the BG6, but it wasn't there on K-20, K-5 and k-3ii and I still believe it's some lousy design with a cheapish look.
But as it doesn't affect any functions I can/must live it.

That would be quite something, wouldn't it? So, you need to move up to the (most probably) best FF camera on the market in order to avoid such (for me undesirable) extra features.



Sorry, but what's that supposed to mean? Unavoidable (ie necessary evil) or intentional (ie useful feature)? If the latter, serving what purpose?

Just checked again on my K-3ii: nope, tight fit no gap.

Well, maybe I'm too picky and the best thing to do is keep the grip.

Nobody without a gap, really?

Happy New Year to all of you,

I have posted this in another thread, but maybe it was overlooked.

I am a little concerned regarding the BG which came with my new K-1. There is a small, but clearly visible gap between the camera body and the grip. With one eye close to it I can even look through.

I know that there is another thread about this topic where some users stated that this is a normal thing, maybe even a design feature. However, since the BGs on both my K-5 and K-3 fit tightly, I am still inclined to regard this as a QC issue taking into consideration that dirt/moisture might enter even though the contacts are covered and the grip is fully functionable.

So my question is: do any of you own a BG where there is no such gap? In this case I would send it back and hope for a better copy. I mean, this thing costs €200,-, can't one expect it apart from functionality to be aestetically pleasing as well?

Well, I need to put this into perspective. Yesterday there was some better light with even a little sunshine and the 70-200 worked noticeably better: AF more accurate and images sharper (even @ f2.8 quite usable). I'll still have to check how sharp they are on the edges, but I'll need a proper setup for that.
I must repeat that the 28-105 is really amazing @1/200 and faster as is the cheap DA50 1.8 even wide open.
At the moment I have found some peace of mind regarding my Pentax gear which, hopefully, will not be disturbed when the FA 31, FA77 and the DA 150-450 have arrived from the UK next week. PF has talked me into buying them, you know :-) I'll report back to you.
Thanks again for all your patience and help!

IRRC there are but two versions. Since I bought the lens this year, it has to be the newer one. Anyway, I don't think the problem is related to the version of this lens. There are so many reports of happy users (like yourself) and some who complain about its performance on the K-1. With MF I can get good results, but this is quite a bit of challenge because of the very short focus throw. I think AF is the culprit, maybe because of a bad contact as the lens has some rotational play when attached to the body. Does the same on the K-3ii, though. I'll do some further testing and if results turn out to be unsatisfactory I will send it in (still under warranty). The good thing is that the service point for Pentax does Tamron, too. If that fails the Pentax 70-200 will replace it.



Thanks! I'll give it a trial although I hope when being forced into LV that I can use my bean bag instead.

Has anyone an idea if this "thing" could be fixed through software, ie by making ES available for OV?



It surely is annoying.



Well, I was about to do that same thing. Still not 100% sure if I'll stay by my decision because

1) the shutter shock issue isn't completely gone, I'm on the safe side by 1/200. Then with faster speeds the 28-105 starts being very enjoyable.
2) I find it hard to get my Tamron 70-200 working on the K-1, the AF seems to have a will by its own. MF + LV shows that there isn't any optical flaw with the lens; still needs some research. K-3ii (as said above) very fine even with the new Pentax TC.

On the other hand, I tied myself a bit closer to the Pentax brand. Couldn't resist SRS's XMas special coupon offers.

FA 31, FA77 and DA 150-450 are on their way to Germany. I must be mmmad.

You are right, for sure, but as I said, the weather yesterday was horrible, as it is today. When I look into my garden it's almost a b/w image. I keep looking forward to better conditions which will let the K-1 shine (stupid pun).



I'll give them a try later today. Wait, there is something else these days, what is it? Anyway, I'll check the Tammies with LV, too, as you recommended.



It's not such bad idea, really. One may not want to always carry a tripod, but a beanbag can be stowed away quite easily + emptied/refilled quickly (mine's a ricebag, actually). It can give the camera a firm rest if there's a wall or anything similar at the shooting site.
You're right. Didn't turn SR off, maybe I should. When shooting from a tripod I couldn't forget that, because with IR remote/self timer the camera does it for me.



I read that, too. Still, I think that the conditions for PS to be fully usable are quite limited (no wind, tripod) + a bit tedious PP. I find myself using PS not that often. But still, the results one can achieve from either camera probably don't differ that much (for landscape, at least).

The replacement has arrived. What I can tell so far from some 100 quick and dirty test photos is that there is a visible improvement: reasonably sharp images (beanbag + PDAF/CDAF) at shutter speeds even around 1/100, so no shutter shake, as it seems. Didn't check on my other two FF lenses yet. Weather is terrible, not too cold (+5), but light like a greyscale. No good testing conditions at all. If of any interest I can provide you with further info later.
So, this is not bad news. The K-1 will probably stay and I save a bucket of cash as I can now hardly justify the purchase of a D850, that amazing beast.

One more thing which is of some importance to me. I find that the BG6 doesn't fit as well as the D-BG5 does on the K-3. There's even a small gap between grip and camera which as I've learned in an other thread is a feature ;-). I don't know, it seems a bit cheapish to me + through that gap dust and dirt may enter.
Is that a common thing or are there any of you whose grips fit closely to the body? In that case I'd take my chances and ask for a replacement.

No need to apologize, of course, as you weren't wasting any of my time. In fact, I am very grateful for any contribution that might solve my problem. I sincerely hope (and still believe) that the problem was caused by some technical defect rather than my own inability (which I'd never rule out as a possibility).




That gives me some hope ;-).



You are right, of course, but with a focus point placed in the center, for example, on a contrasty subject and BBF one wouldn't expect blurriness over the entire frame.

Well, if the replacement shows the same kind of 'behaviour', it has to be me. Damn, postwoman just rang - no K-1 today.

Yes, of course, I mentioned it earlier.



Yes, but isn't this the way how it's done normally?



No need on the K-3ii, I can get satisfying results without it.



Oh yes, but this would only be manageable from a tripod/beanbag, not handheld, I suppose.



I find the Tamron 70-200 very sharp on the K-3ii even wide open (i.e. f2.8). This maybe a different story on the K-1, especially regarding the edges and corners, due to the bigger sensor?

Yes, I am. But tbh I didn't try because it definitely doesn't work on the (my) K-3ii (other users have reported the issue, too), so I assumed the same to be true for the K-1 (shame on me). That would be good news indeed if coupled with the K-1 one could use the Tamron 70-200 in LV mode although I don't like LV too much; but still, one option more is always a good thing.



That depends on the lighting conditions. "Normally" I use PDAF AF-S (Single Sel) f7.1-11 and if possible/necessary a beanbag or tripod.



Yes and no, I think. For many occasions I find LV+ES a little annoying and it surely is not for the quick shot. TAv might force you to bump up ISO (which I wouldn't like too much even with the K-1) or use a wider aperture, which might not be desirable, either. It has been suggested elsewhere IIRC to use PS and then just the first frame for which ES will have been used. Well, mabe, but... And all this in order to avoid the abysmal 1/x range. So, it's still a compromise, and imo a huge one considering the 2k spent on a hobby. But since there are so many happy users I have not given up hope, yet.



Thank you, tomorrow I'll know.

When I look at photos posted on this forum I am easily convinced that I can't hold a candle to many/most of you guys here both aestetically and technically. But still, considering those many settings I've tried out (different lenses, handheld/beanbag/tripod shots, SR on/off, PDAF/CDAF etc) I'm tempted to say there's something wrong with the camera and/or lens. The only convincing results I got were 28-105 LV+ES, Tamron 90 @ 1/320 + f2.8 (from tripod and beanbag) and randomly a few with Tamron 70-200 (LV not possible with Tamron). And then of course there are similar reports from other users.

Be that as it may, the K-1 combo is on its way back to the retailer, who btw is really cooperative (sent replacement before having the faulty one back).

As soon as the new one is here I'll check it out and, of course, report back to you. So, wish me luck (and some better light in this North German winter).

This is my observation, too. On the K-3ii the 28-105 performed better than on the K-1 (maybe due to a lighter/smaller shutter) but, as I said earlier, not as well as the 16-85 (an excellent walkaround lens). So this "sort of resonance in the DFA" could be a QC issue, since not all samples seem to be affected, which is obvious from other users' experiences.



If anyone would tell me why I when trying to upload images get the "Error 404! Oops page not found etc", I'd gladly provide some samples, too.



That's a HEAVY crop, but I can see the same kind of ghosting as in my own images. The first one looks quite alright (very low resolution, of course) as it does (misleadingly) on the camera screen.

@agp1337: on my screen they look fine with their low resolution! So, maybe you got lucky and have a good copy! I still wonder how much "luck" it takes statistically.

In my understanding (if correct) it might help too add some weight to the camera either with a battery grip or a heavier lens. This is what some of the guys here said. On the 24-70 there is no SS problem reported yet afaik.

I know, I know there's too much light for most part of the day :lol: And then it's hot, very hot!

---------- Post added 12-19-17 at 02:36 PM ----------



I'd love to know what that might be.

I just took some pictures which I failed to upload (error 404 page not found). Anyway, in this case I pressed the camera against my bean bag (SR off) 73mm @ f5.6 + 1/125 which normally is a safe bet. It resulted in some blurry images with recognizable ghosting along horizontal edges. So, what?

Didn't read it, but I think you're referring to that camera's being prone to SS, too? Does the D810 cope with that problem? Maybe too early to tell for the D850. Anyway, I'm not considering to jump ship, or am I? No, that'll be some 10 grand (with good glass).


What you call a "special feature" seems to be affecting not only the new Pentax 28-105 but also my Tamrons 70-200 and 90 Macro (handheld and on both a tripod and a beanbag) under relatively normal conditions. Sorry, but I can't think of any expression other than a HUGE disappointment - without any intention of bashing Pentax , a brand I've been very satisfied with for more than 10 years...



Thanks, this is something I was expecting to get.



As I said, I am using the AF button with AF deactivated on shutter release (no apology needed, of course). I have used both single and 9 points. To repeat myself: the 70-200 works flawlessly on my K-3ii. Is the K-1 known to have problems with screw drive lenses? Never heard of...



Good to hear! This one is on my road map, too. And don't you dare use the word 'disappointing', it's a special feature ;-)



I always carry a bean bag when on tour and I tried it with the 28-105, to no avail.



I have experienced similar results handheld and with tripod/beanbag, SR on/off (handheld only) with 3 lenses. Am I really jumping to conclusions?

Today I'll return the combo and ask for a replacement as I may have just got a faulty copy and as I still want to use the K-1. A probable solution could be skipping the 28-105 and getting the 24-70 instead, which doesn't seem to be prone to SS. On the other hand, this lens has been not so enthusiastically reported on by some users. And maybe the battery grip (which I'm going to get anyway) could help, too. It's been said elsewhere on PF that it makes SS completely disappear even with the 28-105. Any observations to the contrary?

Cheers

So this really is an amazing forum! Thanks to all of you.

But alas, my problems aren't entirely solved. So here's just a short feedback because unfortunately I've to work (at least for the 2 grand). Sorry, no time for posting pictures, perhaps later.

1) I can get very sharp images from K-1 + 28-105 with very short exposure (1/320 +). SR off handheld. AF (center point) seems ok, fine adjustment perhaps needed to a small amount. So, the proposed workarounds are the way to go. Well, don't know yet.

2) Counter-checked lenses on the K-3ii, worked fine. 28-105 maybe a little less convincing than the 16-85.

3) Problems with my Tammies still unsolved. They are tack sharp on the K-3ii (70-200 needing +6).
@ 70-200: With the K-1 and the 70-200 I can get sharp images randomly. If unsharp they are worse on both sides of the focal plane, so probably not a AF adjustment problem. As I said above the K-1 tends to change the autofocus automatically just by a fraction. If I'm correct it should stay in place once focus is acquired, but when pressing the AF again after a few seconds there's a small readjustment. AF is deactivated with exposure release, of course. This doesn't happen with the K-3ii. So, it's supposedly a K-1 issue or the combo?
@ 90 Macro: I got a stunning image @ f2.8 + 1/320 (VERY sharp + in focus), but worse results when stopping down, only to be ok again @ f7.1 + 1/50. So, PDAF seems to be working correctly and shutter shake the culprit.

Maybe the tripod is to blame (Dörr Airpod 160 with Giottos MH 1300 head, quite alright, but far from pro for sure). Since it's the only one available I won't find out.

I still have time to make up my mind, but I think I'll try to get a replacement.

@ biz-engineer: "you have to use liveview to avoid shutter shock. It's very convenient.
Typical use case, using OVF as primary mode for a DSLR
- adjust aperture / iso, if you are in Av mode
- frame your subject
- check your shutter speed
- if the shutter speed is faster than 1/200 you are lucky you can take the shot.
- if the shutter speed is between 1/30 and 1/200, bad luck, remove your eye from the viewfinder and switch the camera to LV mode + ES
- now look at the LCD instead of the OVF
- recompose the shoot
- check exposure
- refocus
- take the shot

when photographing people, hopefully they are very patient..."

I like that!

Cheers

Hi all,
being a constant reader, but a rare poster on this marvellous forum I really need to address you for help.

4 days ago my new K-1 together the DFA 28-105 (€2,000, not a bad deal here in Germany) arrived and boy was I excited. After K-20D, K-5 and K-3ii now the gold standard! Off I went taking pictures, but what the #*?/. Not a single one in focus, all blurry! Well, probably shake related, I can't yet master the 36 MP @ 1/125 give or take. Do some proper tests, you fool! This I did, hopefully.
Put camera on a sturdy enough tripod, remote release (3s) on, SR off, pointed at neighbour's roof 50 meters away, which was lit by the winter sun. No wind at all. Iso 100, 1/125 @ 5.6, which is wide open @ 105mm. Didn't work: very strong blur everywhere, definitely no BF or BF. Same with different settings. Next try: LV and ES, et voilà, picture reasonably sharp all over. An obvious solution comes to mind (please do correct me, if I'm wrong): the notorious shutter shake. I have studied almost every thread on PF regarding this topic.
Btw, similar results could be seen with my other FF lenses the (HEAVY) Tamron 70-200 and the Tamron 90mm Macro (no LV support for them).
Especially the latter showed some interesting results: wide open, i.e. f2.8 @ 1/320 the image was razorsharp, then stopping down (and entering that dangerous range from 1/200 and below the outcome deteriorated significantly showing even some slight ghosts of nearby twigs. It got better again with f7.1 @ 1/30. So, this has to be shutter shake, hasn't it? If yes, there's no doubt about sending that combo back. Those workarounds discussed here and elsewhere are not for me. I want to take photos (just like with my wonderful K-3ii, which I'll keep anyway as a backup) without being always on the alert for potentially ruined images.
My questions are: how good are my chances to get a decent copy of the K-1? Are all K-1s affected by that problem, but to a varied degree? Can anyone confirm that his/her copy WITH the 28-105 does an excellent job even between 1/80 and 1/200?
One more thing: with my Tamron 70-200 I observed a (maybe) strange behaviour. After focussing and then releasing the AF-button the focus didn't seem to be fixed (a zzztish sound could be heard from inside the camera as if the focus was changed by itself) and after pressing AF again there was a slight readjustment. Is that normal or am I missing something? Camera was on tripod with no movement and no SR.

I know, the decision is for me to make, but some advice would be appreciated. Because, you know, I want her so badly!

Kind regards

Well, not quite...

About 2 weeks ago I got my replacement which I checked out during a short trip to London (btw great weather & very nice shooting conditions).

Regarding the 'string of pearls' and FF it seems alright, BUT during that trip my new (? 7/2011) just froze 3x, which required removing the grip and the batteries.

And again, there's a stain on the sensor (visible at f11 or smaller), no string, but one that can be done with by wet cleaning - still a nuisance.

So, I'll send it back again (and again and again...)

My God! What a stampede! Sorry about causing it. I just intended to bring to everyone's attention that a major problem hadn't been solved by 3/2011, despite Pentax proposing otherwise. Still, for the vast majority of Pentaxians (dislike this word - not the brand, but the ideology involved) that issue will - hopefully - never arise.

When I got the K-5 in April I did the "obligatory" tests (not to mention the real ones): FF/BF >>> none, stain >>> none.

So, until September I was very pleased with the camera which, of course, IS very good (far better than my photographic skills).

BUT, c'mon: it's still only a bloody camera, nothing to get mad about, in either sense.

AND (if this is of any interest) I will stick to Pentax (btw: giving Canikon a go and selling my gear would burn loads of cash and wouldn't make sense at all).

@ Rupert (What are those little animals? Adorable!)

They are Rock Hyraxes and one of their closest relatives is (believe it or not) the elephant. I took that picture at the Cape of Good Hope (SA) with my (now sold) K-20.

So, Otis always keep this in mind: you're being watched

I do have to add that I was totally satisfied with my K-5 until that bloody stain showed up (@ Prieni: pic was taken in Rome with no clouds at all :D). So, I surely have no intention of starting an other K-5 bashing. And surely with the replacement everything's going to be fine again - or is it?

So, no reason for anyone (let alone the "vast majority") to get frustrated or even jump ... no don't, just don't!
