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 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
[quote:3496ace15f="FrankV"]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. Wow, that's a bold statement, although unlikely it may just be a duff camera.[/quote] Indeed it may be....

AP publishes a full review of the K-3iii
I rewrote this 4 times and each time I reworded it the post still sounded like I thought Pentax had reached the end of the road. Should we loyal few care what the pundits think? Sadly, in my view, yes. For if Pentax is to have a viable future, which I for one should like for at least as long a...

Have a K7 and K5- what next?
I was in a similar position of looking for a used body which would not break the bank. I came to the conlusion that the K5iis can deliver a lot of image quality with great usability for the used prices (sub-300€/£250) I've seen them go for. I just couldn't justify the price jump to a KP (new or used...

Pentax Considering an Astro version of K3III...
It doesn’t look like an updated full frame camera is coming any time soon which is a shame as I would really like to see one with the focusing capabilities of the K3.III and maybe a 45mp sensor. I didn’t see the point of upgrading from the K1 to the mk 2 version but a bigger change could be worthwhi...

Rule of Six
just bring in the autofocus improvements from the K3.III and increase the megapixel count to around 45. Surely those could be done without altering the body much The body wouldn't need to be altered but the software would and the electronics hardware probably would. Is the current processsor and ass...

K1 or K1ii?
A K-1 user here since 2016. I mainly do pet portraits and architectural/landscapes. I never thought the K-1 II was different enough to warrant a change. Given your interest in wildlife/air displays, if I were in your shoes I would be looking at a K3 III instead. Improved AF and functionality with...

K1 or K1ii?
Much against what I consider to be my better judgement, I'm thinking of buying a K1. I have quite a few assorted full frame lenses that should be fine for use (I hope!). The question now is, if I don't faint when trying to pay for it, which model should I get? From reviews, it seems that each model ...

K1 or K1ii?
Don’t let the negative responses put you off, I have had a K1 since launch and it is a great camera, no question. Just because someone doesn’t use pixel shift, or the multiple exposure options, doesn’t mean they shouldn’t be of value to you; I use pixel shift regularly for static objects with lots o...

Upgrading from KS-2 --> which one?
I went from a K-S2 to a K-70 a while ago. The K-70 is very similar, ergonomically, but with an upgraded sensor. Where is the K-S2 letting you down, in your opinion?

K1 firmware link v1.60
It could be that it can't 'read' the card, hence nothing but normal screen, so either the card/contacts or file is the cause. Try reseating any card in slot 1 a few times to clean it in effect, my update went ok with the DCIM folder still there after formatting in camera FWIW. as another in here had...

Tilt/Shift in the bluebell wood
Hi Steve, you are not increasing depth of field but simply changing the focal plane: in normal situations the focal plane is parallel to the camera sensor so that things nearer and further away are out of focus, by tilting the focal plane that depth of field stays the same and instead items above an...

Tilt/Shift in the bluebell wood
Basically Kris the TS lens is doing the same as your bellows-type large format, moving and angling the lens relative to the sensor/film plane. I am always curious how the bellows type works as the image circle from a TS lens is larger than a conventional lens so that the sensor stays within the circ...

Simple bodge to use IR remote from behind camera
My K-S2 has its sensor for infrared remote control at the front, like many other recent Pentax DSLRs . Annoyingly one needs to have the IR remote in front of the camera to get it to work. The camera will just about pick up the IR signal up to about 90 degrees on the 'starboard' side. A big lens will...

Simple bodge to use IR remote from behind camera
Or put a small mirror (shaving mirror? Borrow one of your other half's compacts?) on the window sill, angled to reflect the light to the remote-sensor?

Odd Live View
The normal behaviour of live view with my K3 is that the brightness of the image on the rear screen depends on the exposure value - increase the aperture or exposure time and the screen gets brighter and vice versa. However, with the Laowa 25mm macro, that does not happen. Brightness varies with ape...

I think the + - EV results with an AF lens or an 'A' setting lens are electronic interpretations of what the sensor is seeing. Remember that the iris remains wide open until the shutter release is pressed so whatever you do with the EV button won't physically affect anything at all up to that point....
