Another 16-85 problem
I said I would report back on how this went. I bought this lens from SRS, so I contacted them when it developed a fault. Today I received my repaired 16-85 back from SRS, and it now appears to be working perfectly. I have to say SRS's outstanding reputation for customer service is fully justifie...

Tamron Adaptall 17mm lens + Filter?
Just looked at the one I have and there is a thread in the hood. Really must put my SP lenses up for sale one day, these days my eyes make manual focus a bit difficult.

16-50 De-Centered?
I recently had my 16-85 repaired by Pentax (right side blurry on images, original thread here ). It seemed okay when I got it back, but I decided to cut my losses with it and trade it back to SRS. My initial thought was to go back to Sigma, having previously owned an 18-50 for a number of yea...

16-50 De-Centered?
I am very surprised at the poor overall definition of your photo obtained from your 16-50 :shock: All of the Star lenses that I have produce very very sharp images. The auto focus on my 16-50 (and the 50-135) can be VERY slow to wake up though. With mine I always watch the lens focus and make sure...

16-50 De-Centered?
I feel the problem here is that the image is being assessed is the wrong sort of image for that purpose. Even at f/10, only one plane of focus is the sharpest and althjough we should have plenty of depth of field, it depends on where we have focused and how far the various components in the image ar...

16-50 De-Centered?
The 16-50mm is indeed known for poor quality control as well as the SDM problem. It's not a lens with a good reputation and if I were you I'd take it back.

16-50 De-Centered?
Jonathan-Mac (above) said.......and if I were you I'd take it back. My feelings also. If you don't already have one I'd get an 18-135 instead. It may not be as fast or quite as wide but it has a longer zoom which I've found very useful and also good for pseudo macros. I got mine as the kit lens...

16-50 De-Centered?
If diffraction is evident at f10, then I would deem the lens not fit for purpose, This is APSC we're talking about, right? not full frame? The smaller the format the sooner diffraction sets in. The EPZ review has this MTF test chart: https://www.ephotozine.com/article/pentax-da--16-50mm-f-2-8e...

PU Site Text colourscheme
Hi, I'm not sure what direction to take here, I can add a basic colour scheme toggling option to the upgrades list (light background/dark background), but can't offer a timescale to when it might be done, might not get scheduled for a year or more. I appreciate when Pentax User was reskinned a...

Sensor Clean on K3ii
I recently had my first wet clean on my K-S2 performed by Jessops. They gave it a couple of goes as I wasn't totally happy after the first one. Nice to have a clean sensor back and no problems to report. I'm not brave enough to do my own clean.

K3 Live view
In live view on the K3. I don't seem to be able to change the focus point around the screen area. The way I did with the KR. I have to focus and recompose the shot. I muck prefer the system in the KR live view. However, am I missing something? Regards Ian

Change the LV focus mode to SELECT and use the rear wheel and direction buttons to change the size and position of the AF area.

K-1 ‘breathing’ query.
I have never noticed this before but it is worth noting that any zoom lens where the volume inside changes as you zoom needs to breathe somehow, otherwise you physically would not be able to zoom. With a weather resistant lens it makes sense that the most likely place is going to be at the mount end...

K-1 ‘breathing’ query.
This is weird but normal behaviour for the 28-105 and 18-135 lenses from what I've seen. It's due to the weather sealing. I first noticed it on the K-3/18-135 combo after a quick zoom motion popped the rubber mic cover open. If you open up one of the rubber covers it should probably be easier to ...
