DA lenses on Full Frame: Test Shots thread
Posted By: falconeye, 07-07-2008, 02:50 PM

Hi everybody,

I would like to open up a thread dedicated to one topic:

DA lens on Full Frame: a sticky test shots thread.

This thread shall be dedicated to test shots of a DA lens mounted to a full frame body (e.g., a film camera body). By test shot, I mean shots dedicated to evaluate the performance. Shots of ordinary subjects aren't suitable to this task, normally, and should not be posted. So, these are the rules:
  • K mount lens dedicated to the APS-C form factor is used.
  • Image is taken full frame 36mm x 24mm.
  • Lens hood was removed.
  • And ideally, no filter is mounted.
  • The aperture used is specified (note that film cameras don't record EXIF...).
  • Sample image shows the entire field of view.
  • Sample image(s) show(s) corner, border and center performance at 10MP-100% (multiple crops, or single not-resized image).
  • The subject is such that resolution and vignetting at the borders can be compared to the center.
The idea behind this thread is obvious: To compile enough data to assess the spectrum of available lenses for a forthcoming full frame DSLR in K mount.

#################################################

Table of results as obtained in this thread (updated regularly):
SMC Pentax-DA primes...
SMC Pentax-DA zooms...
Sigma K mount DC...
  • Sigma 18-200mm f/3.5-6.3 DC: -
  • Sigma 10-20mm f/4-5.6 DC: - (below 14mm, Gooshin)
  • ...
Tamron K mount Di-II...
  • ...
Overall rating scale:
+++: no significant difference between APS-C and FF corners
++: difference but usable at full aperture with a small loss in corner IQ only
+: usable staring at f/4~f/5.6, with no or a small loss in corner IQ only
o: usable at f/11 or with big loss in corner IQ only
-: not usable

There's a JJC knock-off of the Pentax 55-300 hood for $5 on one of the big online retail sites. If I was cutting up a hood I'd go there instead of the factory *55 hood.

You can buy a third party hood for the DA 55-300 for around $10. I found the petal style hood worked very well especially since the front of the DA*55 does not rotate.

Here is a DA 55-300 hood for $13 and it is not from China.

Here is a petal style hood for $10 that would not need any modification.

I have stickied your thread. I do note that a number of the links in the table are dead.

Thanks for sticking the thread.
Note that I no longer regularly visit this forum so won't keep links alive if somebody moved the pages around ...

P.S.
This thread now lives for 10 years and never went havoc, or died. Probably never happened anywhere else in the internet

Hello, dear colleagues! I apologize if I take your time. Now I want to pick up a telephoto lens for my new Pentax K 1 2, and look at the Pentax HD DA 55-300mm F / 4.5-6.3 ED PLM WR PE. Please, clarify my doubts about this lens. I read that it vignette to 100 mm. And how next? Are there a frame distortions from 100 to 300 mm? And generally speaking: Can you recommend this lens to my camera?
Thanks!

Vignetting will be even on APS-C above 120mm.

Distortion is not very high on APS-C.

Wouldn't recommend this lens for the K-1.
Better get an F 70-210mm 3.5-4.5 or wait for the 2019 D FA 70-200mm 4.0 lens on the roadmap.

angerdan, thank you for your reply! Thanks to you, I made the right decision! Regarding the F 70-210mm 3.5-4.5 - I heard good reviews, I will look for it.

Wlad:

you might want to consider the DFA lenses if you want a lens designed to work with either FF or APS-C camera bodies

" About the HD Pentax-D FA Zoom Lens Series
HD Pentax-D FA zoom lenses are optimized for use with Pentax Digital SLRs. They cover the 24x36mm full frame image circle, but can also be used with cameras with an APS-C size sensor. They can be used on such Pentax film cameras that have provision for setting the aperture from the camera body.
Auto-focus (built-in AF motor, no support for screw drive)
Auto-aperture (no aperture ring)

aslyfox, thank you! I look at this type of lens, of course. Now I use HD PENTAX-D FA 24-70mm F2.8 ED SDM WR. I will study the material on your links. The only thing that stops when choosing these lenses - their price.
