K3iii a few initial thoughts
I've managed to 'fix' a couple of SDM lenses using an experimental method of using WD-40, contact cleaner and multipurpose lubricating oil. If I lube the motor up too much, it spins but won't seem to catch the focus mechanism to move the elements. If it's too dry then it just doesn't shift. There...

K3iii a few initial thoughts
I had mine delivered this morning, I'll be starting my 2021 racing seasons photographic duties at a 'behind closed doors' banger/stock car meeting at the weekend. It'll be a good test of the auto focus while tracking fast moving cars. I've noticed that Pentax have removed the facility to check if...

K3iii a few initial thoughts
On Sunday May 2nd I tried out my new K3 III at the first stock car/banger meeting of the 2021 season (run under covid guidelines)....photos are in the 'Your Photos' gallery. My initial thoughts are that I am a little underwhelmed with the performance, the image quality doesn't look much differenc...

K1 & FA 50mm f1.4 lens fine focus calibration issue
So I've adjusted the FF on the K1 for my lenses but the 50mm gives me issues. I've a sheet of paper angled at 45 degrees away from me with horizontal lines on it. 2 sec self timer set, set to f1.4, focus on the middle line & take a shot. Zoom in on shot image & it shows front focus. Don't alter an...

K1 & FA 50mm f1.4 lens fine focus calibration issue
So the camera isn't finding the same focus point each time meaning any fine focus adjustment isn't final. That happens with PDAF, although a 50% miss ratio is very poor. 10% is quite normal Why's this particular camera/lens combination giving differing focus results. I would give the AF s...

K1 & FA 50mm f1.4 lens fine focus calibration issue
Must admit I hadn't tried it at the extremes, I'll give it a go. A quick blow around with the rocket can't hurt either. Thanks for the input

K1 & FA 50mm f1.4 lens fine focus calibration issue
Must admit I hadn't tried it at the extremes, I'll give it a go. A quick blow around with the rocket can't hurt either. Thanks for the input Mirror up and the AF sensor is in the bottom of the mirror box Do 10 tests from each extreme to get an accurate assessment.

K1 & FA 50mm f1.4 lens fine focus calibration issue
I just recently bought a K1, to say it’s a disappointment is an understatementi. It doesn’t focus properly.

K1 & FA 50mm f1.4 lens fine focus calibration issue
The K1 is a superb camera, there's obviously something wrong somewhere, care to elaborate on " it doesn't focus properly " what lens are your using, settings etc ?

I just recently bought a K1, to say it’s a disappointment is an understatementi. It doesn’t focus properly. The k1 focusses perfectly, you are doing something wrong.

K1 & FA 50mm f1.4 lens fine focus calibration issue
so before declaring him incompetent perhaps it would be better to find out those settings I am so used to folk moaning on forums of all types these days that I give these kind of posts short shrift. If he wants help i have lots of experience fine tuning lenses with the K-1, and have offered tha...

Eye piece magnifier or screen magnifier.
Hi to all at Pentax user ,just a quick enquiry about an alternative eye piece on the Pentax k70. My eyesight is not what it was but I can clearly see the image and settings on display in the viewfinder, thank God for the diopter. I do however focus manually on a lot of occasions and I feel lik...

Eye piece magnifier or screen magnifier.
I concur with the Pentax 1.2 eyepiece. Have one on my K S2 and never leave the house without it. I also use the right-angle eye attachment by Pentax on all my cameras. 1x and 2x selectable. I have had that for years can still be found used. It makes low-level:lol: and high-level camera positions eas...

Another K3 mk.III thread
it looks a great camera but that it is likely to be the last DSLR to be made as the world has moved on to mirrorless. In other words don’t buy it! While I agree Ricoh SHOULD be advertising the K-3 III a lot more why change the habits of a lifetime and start now, it's not like they have been prolific...

Another K3 mk.III thread
The focus point issue is really my only complaint so far, and I've noticed it mostly indoors in poor light; in those circumstances I've taken to assuming the autofocus will get it right without my intervention, which is not my usual way of working but has so far worked OK; however I would prefer to ...
