Focus Charts for MF Lenses?

ah k, gotcha.





Ah... sorry, you lost me here a little, care to mansplain to me at all (it's ok if you cbb lol)? OOF = Out Of Focus? PDAF = ? And the whole passage in general I am lost a little. I think what yer hinting towards is that the focus system locking onto 'bokeh' or out of focus areas can happen and it's not always user error. I can present quite a few images whereby I have SEL selected (single point, one square above centre), am shooting a public speaker for example, have AF confirmation (green hexagon), take the shots, but upon review the speaker is in no way in focus, way off, and the back of the persons head in the front row was chosen (even tho they might not be at all near the speaker or the focus confirmation point). We're talking about massive soft shots here, not a fine adjustment issue.
Anyway, didn't mean to steer this towards a Pentax AF bashing session, I've owned a K-1 for over a year now, and I like to think I can take some nice shots with it, I know many times I am at fault to blame for missed shots, there are a plethora of reasons why, from badly chosen settings, to being late with squeezing the shutter button from the point the focus was confirmed, I and the subject have moved etc etc. But at the end of the day Pentax does seem to feel there was room to make the AF system better (K-1mkii) and that Pentax as a brand is not known for having the greatest optimised AF system out there (they excel in other areas such as WR and Landscape/IQ). What all this means is that there seems to be a lower success rate when shooting, when you nail a shot however it's spectacular :)
Trying to increase my skill level was in part motivated to stop me hating Pentax for it's mistakes (when likely it was more me anyway hehehe) and instead shift the failure of the shot towards me, I can get better after all... I'm just not sure Pentax AF can.





Same, I've used that from time to time. Very handy.

Ha yeah, I get that, I too can be a little critical of selective colour also, sometimes I think you know quite quickly if it's gonna work or not tho. Thanks for commenting! :)

Focus Charts for MF Lenses?

I used to use Focus Charts, but yes quite quickly in the field you can tell with 2mins of tinkering if the lens benefits in clarity and focus in either direction by repeat testing, adjust, test, adjust and so forth. But of course there are many scenarios where that time spent is not possible, shots need to be fired off quickly.

There are a few reasons that put me onto getting (or trying) more proficient in using MF mode. One is that I am keen to have a play with focal lengths and apertures such as 85/1.4 and 135/2, but can't afford the AF of these kinda lenses, but my budget will extend to the MF variants of these combinations. Can I handle shooting a portrait session for example with MF glass? I dunno... best try using MF exclusively with all lens and see then!
The other motivation is I am just unsure of how good the AF confirmation/system is on my K-1, whether it is poor in relation to other brands, or just user error, but at least when moving away from it and shooting MF then I can take more the blame than blame the camera (ie, confirmation point confirmed, hexagon is shown in Viewfinder Overlay, take shot, review, subject is blurry, focus is way off... grr...)

I'm starting to realise that my month of May testing MF technique may have been skewed by the fact I ignored Fine Adjustments, thinking that I'm in MF mode it doesn't apply. Some of those days I ignored it (for example when framing a shot and wanting the focus to being not on the centre point anyway), but I am now wondering if the times I was using centre point and AF confirmation that I had my settings all wrong, and basically subject to the same follies as using the AF system fully (I just manually took myself there...).

I am indeed a slooooow learner lol

The only time I have comfortably used LiveView and MF is when monopodding, handheld out in the field using LV doesn't 'feel' too great and I believe contributes to my back problems due to the position I am left holding the camera in. I have a 1.22 magnifier viewfinder on the K-1 which helps, I think I would like to try the Tenpa 1.36.
Using LV I think also drains batteries real quick as well.

Thanks everybody for the clarifications and top tips (such as lens cap notes lol, I like that one!)

I've just since noticed that when I have a MF lens attached, the 'Apply One' is greyed out, it's not even possible for that lens to get that option, so I guess that answers the question as to if MF lenses can 'hold onto' individual fine adjustments, obviously a clear no on that point. I'm guessing if the 'Apply One' option is available for whatever lens attached then it has the ability to have that info stored.

I think I got into a bit of a mess, because when I toggled between MF glass and back to AF glass, and even when using Custom User Modes (and powering down and up), if I was last in 'Apply All' then that Fine Adjustment was kept on that option rather than jumping to 'Apply One' and using that setting for the AF lens etc. Gah!

It feels like a lot of hassle of toggling and menu navigation for when lens swapping occurs. I'm wondering now if there is someway to set up a User Mode for each lens that recalls the Fine Adjustment mode and value, rather than when powering down and back on again it remaining 'stuck' on what was last used. Example;

User Mode 1 - DFA 100, Apply One, Fine Adjustment +3

User Mode 2 - Takumar 135/2.5 Apply All, Fine Adjustment -10

User Mode 3 - SMC Pentax A 24/2.8 Apply All, Fine Adjustment -5

User Mode 4 - FA 50mm, Apply One, Fine Adjustment +6

Etc.

Perhaps in the 'Memory' section of the menu I should be ticking or unticking something there so that between power downs and power ups it can use/apply these changes?

But I don't think this will work because 'Apply All' is not 'saved' like Apply One seems to be, so whilst in the example above it's certainly possible to have User Mode 1 and 4, having User Mode 2 and 3 just won't work (is my guess). The above scenario isn't even that ideal because I'm then using up valuable custom modes for lenses rather than scenarios...

So I'm left with (as you say) either turning off fine adjustments and ignore AF Confirmation (remove it from the Viewfinder Overlay entirely) and use just my eye and judgement (which I have been doing a fair bit already) for when working in MF mode, or when toggling glass make sure to look at the lens cap or whatever and quickly make that fine adjustment in the settings (sigh).

More and more I am enjoying the shooting experience of MF, but I also know and need to use AF when it arises. I often shoot MF with my AF lenses, and then toggle the MF/AF switch to AF when need arises, so generally speaking I like to have AF points on the Viewfinder Overlay in case that scenario quickly pops up. Perhaps I need a AF Point User Mode and a non AF Point User Mode (blank Viewfinder Overlay), and ensure that Apply One is on for AF Point and 'Off' for the blank Viewfinder Overlay, that way at least the AF glass will be correct fine adjustments for when toggling between AF/MF switch, I can just simply turn a dial whilst I'm at it...

Cheek! :p:D:lol:
But I think the AF Confirmation spot is no different for MF lens to AF lenses. I tried yesterday for a bit and noticed that the fine adjustments confirmation was definitely significant when using AF confirmation on MF glass. It definitely is factored in.
So I am left with the choice of ignoring AF Frame and spots and use just my eye and take the shot when I think things are at their best/sharpest, or I use the assistance of AF confirmation and fine tune. I'm just a little confused over whether the finetune adjustments are 'apply one' or 'apply all' (ie global or it recalls the glass being used).

So in the past I have used Focus Charts to try and finetune adjust any of my AF lenses. It's recently dawned on me that you might also need to do the same for Manual Focus lenses if using the AF Confirmation point when shooting (centre spot).

Is this right?

Also, will the K-1/KP remember these settings for different MF lenses attached? Or is it going to get confused? Like, I understand that the camera will somehow be clever enough to know when i have tuned for a DFA 100 that when I connect that again it knows the fine adjustments to use, but if I have a few different K mount MF lenses of different (or even the same) focal length, is it going to know which lens is which? Do the old lenses lack certain stuff that modern cameras need to make their identity known etc.

Cheers!

Yeah was a gorgeous day :)



Yeh most of these spots are around 1hr drive away. I live in the lower Blue Mountains, most of the 'cool' stuff happens further up, but then I like being closer to the city (and we need the city for work), so it's a sweet spot to live in for now. Maybe retirement will see us move further up.
It's a lovely corner of the world for sure, give us a yell if you come up, I'd be happy to show you some sweet spots if you're unfamiliar with the area :)

Nope, just a single handheld portrait orientated shot, fired as a 5 bracketed shot with a single button press and the ev values at 0.3 shifts.

The 'merge' was done following (mainly) the procedure outlined here; A Practical Guide to Creating Superresolution Photos with Photoshop

The twist is that the 5 shots had different exposures (shutter speeds) rather than 5 shots all the same.

Sometimes it works out really swell however :)



5 frame bracketed shot taken handheld (0.3ev value shift), combined in PS for intention of Super Resolution process. Came out rather well I think.

I been doing quite a few Brenizer shots in Av mode, often the aperture and ISO remain constant, the shutter speed varies whilst panning around. What's the general advice regarding this, should we bail out of any mode other than Manual for the shot? I have to say I quite like the exposures of the shots using Av mode thus far... perhaps it's more to do with the dynamic nature of the scene. If it's subtle changes Av mode is fine, if it's strong changes from bright to dark manual might be best other wise the stitching could look odd?
