The Sigma 35mm DG 1.4 Art is identified as being an APS-C lens and the auto mode treats it like that. Its works ok if you set the crop setting to FF (Full frame) though. I always thought the DG meant full frame compatible, DC being for a crop sensor. I have read on the other forum that the Sigma ...

Report K-1 bugs/issues here
Did anyone try the sigma 50 150 2.8 with the latest firmware? the camera stops working once it's on. Any advice? if you have tried cleaning the contacts and there is no joy then contact Sigma ... your lens will probably need a firmware upgrade like one of the older HSM 70-200mm f2.8s

K-1 Dynamic Range
Pixel shift requires to move the sensor about. Obviously that is built in to the K-3 and K-1 - for the SR - but not in the 645Z. Pentax documents the challenge of building the sensor shift tech for a full frame sensor on the special K-1 site. As the sensor is heavier and larger than the one in t...

pentax smc m 1.7 50mm on K50
I have been experimenting with this legacy lens on my K50, gone through all the steps, setting focal length at 50mm, Av exposure at f1.7, very high shutter speed etc. However the photos are extremely soft though they do have a beautiful quality. I used the same lens a year ago with an adapter on a ...

pentax smc m 1.7 50mm on K50
Diopter fine. I found an article in Robertdonovan.com that seems to explain the situation. I am sure it would be OK to quote it: "Dialing in accurate focus can be tricky as the range of movement of the manual focus lens’ focus mechanism and front/back focus issues can throw the focus sensor of...

pentax 645z problem sensor
:54 I am posting a few pics of a new pentax 645z with a questinable sensor. Please look at pics and let me know if your 645z sensor looks like this. It looks like someone removed the glass cover (maybe because it was scratched or damaged) and the sensor cannot be cleaned. It is a matte black sensor...

pentax 645z problem sensor
Looks like the shutter isn't open?

pentax 645z problem sensor
That's the shutter. The sensor is behind it and can only be seen if the camera is put into sensor-cleaning mode.

pentax 645z problem sensor
Just checked my Pentax Q and it also looks like the photo's posted above. Must be the way Pentax build cameras. One slight difference though, the grey banding on my Q is vertical, would that make a difference?

K70 Rumoured specs online
Yeah, I can't see the two different model lines continuing...perhaps the K70 will replace both the K-50 and K-S2...given that its rumoured to have a 24MP sensor...possibly the one from the K-3?

K70 Rumoured specs online
I know the back story, that Pentax envisaged the K-S line to be different to the K-50 line, but in practise the K-S2 (at least on paper) is everything you would have expected from a K-50 replacement. I think making the K-S2 weather sealed really sealed this for me, as now the two lines are extremel...

Pentax K-1 Reviews
Dpreview full review out now. Usual Achilles heel for Pentax - AF accuracy and speed and video although I can't see why anyone would want a full frame video camera - after all high quality movies can be 16mm. http://www.dpreview.com/reviews/pentax-k-1 those who understand the concepts actually wan...

Pentax K-1 Reviews
I'm Director of Photography on a tv series set to air in Africa and hopefully soon in canada and we shot an entire season with three Canons, one was the pro video C-100 and a FF d-slr and a aps model. Was a shame.. the opening credits shots here in canada were shot on the K3 in 4k timelapse mode ...

Pentax K-1 Reviews
If the K-1 had all the video wizz-bangs some seem to want but it cost £2599+ to pay for them, would it sell the way it is? Personally I doubt it. If the video DSLRs some want already exist, why would Ricoh/Pentax try and compete in what is in effect a very limited market at that price point. Pen...
