K-3ii to D500... Is this the right move?
Posted By gfurm

I admit I didn't read all 17 pages.
My take on this: I was in the same boat, K3 II, 300/4 and 1.4TC. For perchad birds from hide I had no problems. Then I went to Farne islands in UK to photograph puffins. Out of over 1000 photos shot in 1 hour I binned 850 without even going to 100% view in lightroom due to missed focus. I was fighting with the camera all time I was on this island.
I had a choice: get 150-450 for 1200 hoping lens will be faster and better at focusing, or switch to Nikon D7200 (D500 was out of my budget) and one of the 150-600 zooms breaking even and knowing it will be better.
I went for the latter and my next outing for BIF yielded 1500 photos with only about 200 discarded as obvious missed focus.
I also tried my kid running towards me and Nikon with 55-200 lens nailed every photo while I had problems with K3 II and tamron 70-200 (allegedly one of the fastest focusing screw drive lenses) in the same situation.
I still prefer Pentax menu and handling but for AF tracking performance for me Nikon is much better.

How to cure a Pixelpeeper??
Posted By gfurm

That's a simple one.
I've printed a poster size (it's so big I have nowhere to hang it) portrait of my wife taken at ISO 1600 with available light using K-5 II. It's black and white so a bit of cheating, but it's surprisingly sharp and detailed. Not pixelized at all.

That cured my pixelpeeping and obsessing with noise. I don't shoot Pentax anymore but I happily went to 4000 ISO on K3-II when I had it without even worrying about noise.

I also have A4 size photo of my kids hanging on the wall. One of them has face slightly out of focus at 100% (should have used smaller aperture) but at viewing distance you can't tell.

So print something big and see the results.

Catch In Focus (Almost a great Idea) Sorry for beating a dead horse

Canada_Rockies: in AF2 you need to press and hold back button focus before pressing shutter. I just tried with sigma 18-35 which has AF/MF switch and it works as well.

OK, so I just checked how it works on K3II.

First DA 300/4:
Lens with AF switch set to AF, camera to MF, pressed back button and it fires when no focus achieved.
Lens set to MF, camera to AF, pressed back button and camera doesn't fire until it's in focus.

M 50/1.7
Camera set to AF, back button pressed, camera doesn't fire until it's in focus.

DA 50/1.8
Camera set to MF, back button pressed, camera fires with no focus.


Bottom line:
CIF works with back button but you need lens with AF/MF switch.
Confused myself as I was sure lenses without switch worked. I never use it though so not much experience there.

Are you guys sure CIF doesn't work with back button? I could swear it did.


Switch to MF, hold back button AF and trip shutter? I'll have to check when I get back home but I'm convinced it worked with all lenses, even ones without MF switch and with back button when I tried it. I'll have to try later.

B&W or Color Negative in Lightroom
Posted By gfurm

Yes.

Import photos, go to develop tab and tone curve tool. Drag upper righ point all the way down and lower left all the way up. That will flip it from negative to positive. B&W areeasier than colour as you won't have problems with WB.
Bear in mind that all basic controls will flip as well, so if you want to increase exposure you have to drag it to negative value.

DA15mm for me. Bought it for landscape but them soft corners killed it for me. Maybe I had a proper lemon but it looked softer in corners than Sigma 10-20 I had before. Sold it after 3 months. Starburst were excellent though.

I didn't think they'd go that low on DA* 300 so I bought used in mint condition with 6 months warranty from ffordes for 600.

I don't regret it. Knowing my luck if I waited the used one would be gone and SRS black Friday price would be 800 😀.

Edit: just read above post, lol. Youre right, these are last year deals. 😁

I had similar experience with UK authorized Pentax service centre.

Rang them on Monday to ask about K3 II power off issue, courier picked it up on Tuesday (free of charge), rang them again on Friday for update just to be told it's on the bench being fixed. Had it back Tuesday. 7 days turnaround with weekend in the middle. Doesn't get better than this.

Pentax K-3 focusing screen
Posted By gfurm
Replies: 20
Views: 4,235
I bought Canon EE-S from Amazon and cut it myself. Can't get much cheaper than this.

You just have to calibrate it after putting in camera by using shims. In my case I had to remove stock shim from K-3II and use it without any. Manual focus was easy, especially with longer lenses. I also have Canon split screen cut to size. This one require shimming and I've done it with narrow strips of low tack masking tape. But for manual focusing I prefer the EE-S screen.

Just one warning. A lot of dust can get into mirror box while you messing around with screens. I had dust stick to prism and screen itself. And cleaning the screen can easily get it scratched.

Good luck.

K3 II and beach exposure ????

I slipped on a hillside once and went down a few meters on muddy ground. Half of K3 II covered covered in mud, half of me covered in mud. It all dried out before I got home.

The problem is I don't have WR lens to just put camera under the sink. What I did was put a lot of bluetack on body cover to seal it of and washed camera under the tap, had to use toothbrush in some places. It works fine.

Lens wasn't WR but luckily I always have hood on so glass was clean and only barrel was muddy so I managed to clean it with dry cloth. It took couple hours but it's fine now.

So you can put body under the tap with no fear and it will survive.

Focusing screens for K-50 necessary?
Posted By gfurm

If you on a budget you can buy canon ee-s screen from amazon for 35 bucks and cut it to size yourself. Tape it over with low tack modelling tape (yellow Tamiya), trace over the tape the size of pentax screen, cut with fine tooth saw (I used one for steel). It won't look like Katz Eye but will do the same job for half the price. But you'll have to calibrate it, mine required removing original shim from my K3 II to make it focusing spot on.

As for metering - all lenses I own are f2.8 or faster and I haven't noticed any issues. Even Tamron 70-200 with 1.4 converter (which makes it f4) meters fine.

Even though it doesn't have split or microprism it's great for manual focusing.

I had Kenko 1.4x Pz-AF converter before and the biggest issue was autofocus. It would focus if it was in the ballpark already, but if it had to travel a bit it would just go to the extreme end of focus throw and stay there. So I had my reservations before buying Pentax one.
Happy to say that AF works fine, goes from close to far end and back without any issues. It's not as snappy or definite as lens itself, there's some micro movements just before it locks, but way better than with Kenko.

Image quality - still great. Wide open it makes the lens f4 but at that aperture there are green halos around sharp edges, by f5 they disappear and f5.6 is sharp with no fringing.

Quick and dirty test images from my garden:
https://www.flickr.com/photos/120246773@N07/26214488953/in/dateposted-public/

Slightly cropped, the strange out of focus line going across the image is washing line which I didn't see in viewfinder. It spoils the bird a little bit but you can see around it, eyes, legs and fence pretty sharp.

https://www.flickr.com/photos/120246773@N07/26725247802/in/dateposted-public/

This one was shot through the window, even with glare from it you can still see a lot of details in the feathers.

https://www.flickr.com/photos/120246773@N07/26725197162/in/dateposted-public/
No windows or washing lines in this, just a bit of cropping.


Overall the combo works fine, still a bit short for birds but I don't have 900 quid for DA 300 to put on the converter, so cropping will have to do for now.

On the side note:

It works quite well with DA 50/1.7 but not so much with Sigma 18-35/1.8. With Sigma AF just hunts without even trying to lock. Don't know why anyone would want to put those lenses on the converter though, bigger magnification at close distance possibly?

I bought mine from UK ebay for 40 GBP with M50mm 1.7. I just had to add 12$ for new lightseals (easy to fix). It's not mint condition, only got some scratches. Just make sure battery compartment is not corroded.
Viewfinder is AMAZING. When I first looked through that after K3II and MZ3 I was shocked how big and bright it is.

Ricoh GXR does that, It has distance scale on left side of the live view screen and green band on it showing depth of field amount. Lenght of green bar changes when changing aperture. I guess GR and GR II has that too.
