Leaving Pentax

I had Pentax (K100Ds, K20D, K5, K5-IIs, K-3, K-1, K-1 II) and a lot of lenses (best for me were for example FA31, FA43, FA77 and DA*300) but I sold it all. why?
good focus only on center and not always, the production of new modern lenses has slowed...

now I have Sony A7R3 with EyeAF and good focus out of center (in april 2019 new firmware with animal EyeAF) with Voigtländer 15/4,5 III + Sony FE28/2 + FE50/1,8 + FE85/1,8 and no problem.

what can we expect from CP + 2019 ? GRIII + HD11-18 and that is all. sadly.

K-1mkII overpowered NR. Firmware update?

Fenwoodian: I do not have K-1 anymore :-(


I just tried to compare with K-1 II classical Pixel Shift from tripod (motion correction ON/OFF), handheld Pixel Shift Resolution, handheld ES (electronic shutter) and handheld normal shot.


full scene - K-1 II + FA43



normal shot - electronic shutter - Pixel Shift from tripod motion correction ON



Pixel Shift from tripod motion correction ON - handheld Pixel Shift Resolution



Pixel Shift from tripod motion correction ON - Pixel Shift from tripod motion correction OFF - handheld Pixel Shift Resolution



for me, the best is classical PS from tripod, but handheld PS is also OK. so no big surprise.


but what surprised me was the AF with K-1 II (this I absolutely did not shoot so well with K-1) look at the photos, in different light (sunny, cloudy, in shadow, fluorescent light, at night):
AF-S, spot AF (a small photographed subject and far from me)
FA77/1,9 Limited


FA135/2,8

HD DFA 28-105/3,5-5,6 WR




AF-S, spot AF with composition change, FA77/1,8 Limited @f2,2




AF-C, SEL-2
FA77/1,9 Limited @f2,2







the weak is only 4.4fps and a small buffer






AF-S, spot AF, FA43/1,9 Limited @f2,2
lights off in the office, ISO 3.200

photo taken through a double glass in the window with reflections from inside, ISO 2.500

AF-S, spot AF, FA31/1,8 Limited ISO 16.000 (@f10 due to the ISO test)


I hope that K-1 will also get firmware with AF algorithms from K-1 II :-)
...so where are the bad results from Dpreview?

PS: I'm sorry for my English

I do not believe in all the reviews. I sold K-1 and bought K-1 II.


benefits for K-1 II:
- accurate AF-S (no hunting), better AF-C (only about 5% of inaccurate focused photos)......but only for spot AF point and A-9/SEL-2 mode
- Pixel Shift Resolution to be used handheld without artefacts
- K-1 II ISO 16.000 look like ISO 12.800 on K-1


on the left K-1 II, on the right K-1....the same lens, the same settings (DNG, NR OFF.....export from Adobe Lightroom CC2015 without adjustments)
AF-C SEL-2, ISO 1.250, Tamron AF SP 70-200mm f/2,8 Di LD (IF) Macro

AF-S spot AF, ISO 6.400, Pentax HD PENTAX-D FA 150-450mm f/4.5-5.6 ED DC AW



I would buy K-1 II again if someone asked me.

if you want the same quality like 14-24, should buy Pentax 15-30, especialy for best in class micro contrast. the IRIX/2,4 is good, better corner sharpness than Samyang 14/2,8, but IRIX prone to ugly flare. and Fireflay version has crappy plastic filter thread.

for portraits with AF is there only Sigma 85/1,4 EX DG HSM nonART and Pentax FA77/1,8 Limited.
D-FA100/2,8WR is too sharp and unify look, it is macro lens.

from my IRIX with flare






f2,4 !

firmware1.41 is currently the best for me. FA43/1,9Limited focuses for the first time and accurately (fw1.30 and fw1.40 were not as good with FA43/1,9Limited)


test photos all on f1,9, AF-S, different distances and different light, profil Bright, JPGs from K-1, AF Adjustment -8


central AF point

fw 1.30 and 1.40:

FA43 need +3 AF Adjustment
---------------------------------------------
fw 1.41:
FA77 need 0 AF Adjustment
FA43 need -3 !


Otherwise I do not see any changes between fw1.40 and fw1.41, no hunting AF etc.

Firmware 1.4 vs 1.3: Impact on AF performance
Posted By lennyl

@k1man: You can update fw anytime, no problem downgrade firmware from 1.40 to 1.30 for example. But when you will not have any problem with the firmware 1.40, let you always get the latest :-)


I had one month
fw1.40 and with Pentax FA77/1,8 Limited I did occasionally front focus (I do not know why)


Of course every time after update I reset all settings and again to set everything including AF Microadjust. I am waiting for next firmware (1.50?) because I like bulb enhancements in fw1.40 for landscapes

I'm hobby photographer. I do most landscape photo. I also tried AF-C with my Pentax K-1 and Pentax smc DA*200/2,8 SDM.
I had about 10-15% of poorly focused photos, it's not so bad.

my first K-1 had inconsistent and inaccurate AF (tested with central AF point ofcourse). I made 3.000 shots and no settings did not help.
various lenses: APS-C DA, APS-C DA*, FF FA Limiteds, new D-FA 24-70/2,8...

I sent back K-1 (SRS Microsystems UK) and the new body is OK.

if you want more examples, you can download full size JPGs from my previous post with FF mode vignetting and APS-C mode JPGs also.


i understand very well what you wrote. i want show the details in 1:1, thats all
for me is not APS-C/square mode solution, only a temporary solution who has not yet FF lenses


orignal APS-C lenses have brutal vignetting - for example DA15/4, DA18-135WR and others
