K3 sensor shake.
Ok, thanks for the imput. I since I could not feel it on the newer camera, I was not sure. Just now peering at the sensor under the mirror when I first turn the camera on, it looks like it may shake slightly, but I am not for sure. But if you k3 owners say it is the same with yours, that is good e...

New K-70...anyone planning to buy?
without knowing what the new lenses and focussing system performance actually is... and the variable aperture while recording sounds awesome.. at a pro level I rarely ever use af while recording video... you just can't beat the manual focus "feel" of the older lenses that are designed for manual ...

K1 V Sony A7ii
I was a long time Pentax user (35mm MF/AF then started with the ist DS/K10D/K200D/Q/K30/K5/K-01) but left Pentax a couple of years ago and have recently returned via the K-1. I have used and owned the A7 markII (and the original A7) with the 28-70, CZ 35mm/2.8, CZ 55mm/1.8, Tamron 24-70/2.8 USD and ...

Manual Extension Tubes
Sorry to have to disagree with you both! I have a set of Jessops K mount tubes in front of me as write. These PKA/AF tubes are mint, never scraped or otherwise mutilated and have have no problem passing aperture info between the lens and the camera! I've experienced this issue with some teleconv...

Manual Extension Tubes
I have an un-modded set in front of me now and I had started to photograph each stage of the process to show how the aperture info is not displayed before, and is after.... ...well, step one - testing - the aperture info shows on the back screen in AV mode and I can set the aperture from the came...

Electronic shutter on K1
Hi Both were 1/30 s using manual exposure. Tripod is rated for 5.4kg and head is rated for 4kg. SR was off, and I was using a remote to trigger. Electronic shutter works (i think )in LV by electrically resetting the (already exposed) sensor so the image starts to be recorded. The trailing me...

Chromatic aberration/ the fringe
Some of you will realise that i've not been on the forum for some time. The reason being that i left the Pentax fold after a 38 year relationship and am reasonably happy where i am though i'd like to return via the K1. My last and the camels back breaker was the K3's sensor which suffered terribly...

Chromatic aberration/ the fringe
Thanks for your reply John but I'd only ever encountered it once with the k5 using a m28mm f3.5 and never with the k200 also using a 16-45mm. The k3 displayed it using the 16-45 which I replaced with the 16-85 and it was worse. Reasearch also lead me to conclude that it was indeed the sensor and not...

Chromatic aberration/ the fringe
I agree 100% with the contemporary comment after the article by Semi regarding that review. It seems the reviewer wasn't familiar with the camera enough to write a comprehensive review of it. The point about burning out highlights seems very odd as if its something you'd want to happen. You woul...

Chromatic aberration/ the fringe
Chromatic aberration (fringing) is something that appeared with the digital camera era. Films contains three different layers which are sensitive to the three colors used to reproduce the spectrum we are able to see. These three layers are superposed in such an order as to compensate almost per...

Chromatic aberration/ the fringe
Also CA is a problem with binoculars and telescopes which points to the lens rather than the sensor, I recently switched from Minox binoculars to Leica due to unacceptable CA despite the former using Schott glass with multi-coating.

K3 - Manual focusing - Techniques
You can look visually for the highest contrast or the sharpest line. I never used the focusing aids, always preferring the overall ground glass screen. There is a focus confirmation in the viewfinder, but it's not the red dot. It's the green hexagon at the bottom of the screen. When the green is ...

Q system
Are pentax Q cameras more, or less, likely to get dust on the sensor (because there is no mirror)
Posted by royd63uk on 26/02/2017 - 22:03
Q system
Dust gets under the sensor shield and it's quite tough to get out. The dust on the shield is easy to remove though.

Pinhole Pentax
There will be plenty of videos on YouTube showing the techniques, probably. One way is to make a hole in the centre of the body cap. Then make the pinhole using a very thin sheet of brass, or perhaps even some Aluminium foil. Press a pin through the brass to make a dent, but don't go all the way thr...

Ricoh may close shutter on personal camera business
Sorry Jules, at my annual review with the accountant my eyes glaze over after five minutes so not much help on the details. The medium format range has been a bit quiet recently, Pentax pioneered this format for DSLR type bodies and it has been very successful for them, but others are moving into th...
