Forum: Pentax K-3 III 06-28-2022, 07:47 AM  
K-3iii with older SDM -- DA* 50-135

Thanks! In the mean time my K-3 mark III has been put through the testing mill quite seriously. I'm just back from two weeks in Iceland. Though most action (wildlife) photography was done with the DFA150-450, AF on the screw drive converted DA*50-135 performed really well.

As usual I got a lot of weird looks when I continued shooting in heavy rain while everybody else started panicking and putting away or trying to shield their gear from the elements. Some actually pointed out that I should take more care of my stuff. I laughed it off saying "this is a Pentax, it can take it", and happily continued knowing I would be alright, and I was of course. Happy days!

grtz, Wim

Great! Whereas the 3.5m snap focus distance is probably more useful in the GRIIIx with its longer focal length and thus shorter depth of field, I imagine it could be useful on the original GRIII as well. I'll check what the depth of field range will say at 3.5m, perhaps I'll be able to get faster shutter speeds using a slightly larger aperture than at shorter options to get DOF to infinity and get more foreground in focus than a similar setting at 5m... I'll upgrade on Saturday.

Tx, Wim

I have 8 D-Li90 batteries (for 3 cameras, two of which gripped), the oldest one being from 2010, the most recent ones 2020. FWIW, I do not observe any difference in performance between them yet.

A new DA50-135 sounds great, but there's nothing wrong with my old one. Optically at least, though the AF could use an update (mine has been screw drive converted BTW)... If they could make it a DA50-150/2.8 I might be easier to convince... Anyway, by the time these are reality, we'll be a few years down the road, so we'll wait and see...

Nice!!! Though carrying a second GR III would be confusing to me, as both versions seem to look (and feel) too similar. 28mm equiv is more flexible to me, so I'll stick to that. The 1.5x teleconversion GT-2 does look nice for just in case. I suppose it would fit the original GR III as well? That would turn the GR III into a 42mm equiv and move the crop modes one step longer...

What about the D-BG8 battery grip for the K-3 III?

Thanks for bringing this thread back to my attention. In the mean time I have had my K-3 III for almost 2 months, with the grip. I'm actually using the grip more often than on previous bodies. The main reason is the strap attachment, which is so practical for shooting in portrait orientation. Ever time I take it off to save some space, I realise how annoyingly the strap dangles in front of the OVF when it's attached to its "normal" attachment point on the body. It's a relief to be able to attach the grip every time.

K-3 III L Bracket
Posted By Ishpuini

Same as @Macario, I have one by 3 Legged Thing: QR11 Universal L-bracket system

They fit onto Pentax cameras nicely, although the opening on the side doesn't align with connections on a Pentax body (I don't use those so I don't care). Indeed there is no pin to prevent the bracket from rotating, though I have never had that issue because of the grippy material facing the camera on the bottom plate. Really heavy lenses I mount using a foot on the lens anyway... Most important disadvantage is that the bottom plate partly covers the battery door, so you have to undo the screw slightly to move it to the side when changing batteries.

You are correct in clarifying what I wrote. Reading it again I realise I didn't write things as clear as I should have... I'm not a native speaker...

To be complete, SDM was not the reason I stopped using the SDM DA*16-50, IQ was. After conversion to screw drive it was noisier, but AF worked fine again.

Yes, I have both.

The DA*16-50/2.8 is a completely different beast to the DA20-40. They compare as any recent DA* lens should to a more or less equivalent DA limited IMHO, the DA limited prioritising portability and "character" over performance.

The fact that the DA20-40 was ever considered an alternative or even an improvement over the 16-50 is due to the old SDM's showing the age of its design on >20MP bodies, which the DA20-40 was designed for of course.

The new PLM is a different category altogether. IQ-wise it blows the DA20-40 out of the water, it's as simple as that IMHO. The DA20-40 still has its place as a flexible and compact light weight lens centred around 30mm. I can see myself still use mine from time to time when size or weight are of consideration. But the default workhorse standard zoom spot has been returned to a 16-50/2.8 lens now.

I guess it's a mixed bag, depending on the distortion of the lens. The distortion correction process would result in some areas of the image being slightly stretched and others slightly compressed. The latter could improve the perception of sharpness in that area. The former, however, will result in some additional blur in the affected areas. Next to that, removing colour aberrations that are especially visible on the edges of subjects, would probably increase perception of edge sharpness and improve contrasty texture?
Hence I can see a profile can improve things, though I think it would be limited to subtle changes only... A blurry lens will never become razor sharp thanks to a profile. At least I have never seen this... My DA21/3.2 in any case doesn't noticeably improve after application of the Lightroom lens profile.

Well, regardless of the ongoing discussion, I've given the new PLM DA*16-50/2.8 a score of 9 based on a few days with mine. It's a great lens that ticks most boxes and in some respects exceeds my expectations, but perfection doesn't exist...

A bit late, but indeed getting an entire hood is probably the only way to replace the filter window cover. A long time ago I lost the one on my old SDM DA*16-50/2.8, and I had to buy a new hood as well.

Another welcome from Belgium! Great to see someone with a similar history as I started with a SFXn back in 1989 myself, and stayed with Pentax ever since using a long list of DSLRs and lenses. I used to have that M300/4 as well, though it's now in the hands of a Pentax lens collector. Enjoy your time here!

I was actually considering the DFA21 to replace my DA21 on APS-C. Mainly because the DA21 (much like the SDM DA*16-50/2.8 actually) doesn't seem up to the higher MP APS-C bodies of latter years, contrary to the FA limiteds that are still fine. This was confirmed during a recent outing with the DA21, which resulted in images that really disappointed me in terms of IQ. The other two in the bag that day, the M28/2.8 and the FA43, did so much better. Could be my copy though.


BTW, the widest aperture on the spec sheet is one thing, the widest aperture that gives a nice focus transition is another. f/3.2 on the DA21 was always lacking in that respect IMHO, and I expect the DFA21 to be better at that at least, regardless of whether it is f/2.8, f/2 or anything more exotic and FA limited style.

From the shots that I took so far with my copy, I confirm that sharpness does drop off in the corners a tad, and there is some barrel distortion (with a bit of moustache) to be corrected by a lens profile. I'm waiting to see what post processing lens corrections will to, before I judge what output I can get from this lens at extreme settings. However, the improvement over the old SDM version is still immense.

EDIT: the above applies to 16mm at f/2.8 mostly.

Sorry about that. I have a few images on the card in the camera, but haven't fired up my home PC yet. We've been working from home for over a year now, and my home office space is taken up by work stuff, which means I just don't get around to clearing up enough space for the image processing.

I have tested the lens at f/2.8 for close-up photography of some flowers in the garden, and came away impressed with the bokeh. It so nice, that I might forego packing a fixed focal length lens for that purpose in future. The lens is really good wide open, but I already wrote that.

I the news thread I also wrote that handling the lens on a non-gripped camera is surprisingly comfortable. Normally for such a large and heavy lens, using a grip would seem most practical, but the lens is just beefy enough to align nicely with the bottom of a gripless camera, and as such is can rest flat in the extended palm of a left hand. That makes it easy to hold in a balanced way without the weight of the grip.

One more thing is distortion. At 16mm the lens is not distortion free, as can be expected. There is some barrel distortion and a little bit of moustache too. Much less than in the old version though. I'm looking forward to a lens profile in Adobe Lightroom for this and to see the impact of this correction on corner resolution to evaluate the lens for architecture. I am optimistic about this though.

Just took off the grip. Surprisingly the PLM felt great on the gripless camera. The fatter lens actually aligns perfectly with the bottom of the camera, which means that if you hold camera plus lens on the flat palm of your left hand, it sits very comfortably indeed. YMMV but holding the camera like that may actually be easier than with grip...
