KR Live veiw v Through the lens
It makes sense Ian but that doesn't guarantee it's on focus. There are some margins build in the lens and the AF sensor of the camera so the tolerances aren't 100% meaning the lens might front or back focus. I've checked my lenses and they all needed some correction to make them focus correctly wi...

Auto Focus Liberation
My first real outing with my K5 today, and so also my first real experience of auto focus (21mm f3.2); I've increasingly missed focus with a mf rangefinder, whether through age or increased wine consumption. So what a pleasure to concentrate on the scene whilst knowing focus is on the button! And so...

think of a digital pentax advice please
Sounds like a real raw nerve post there. ?????? I don't have a 645D. I don't feel inferior to those that do. The guy was asking about the K-r. Can we not say one camera performs better than another without people's feelings being hurt? No raw nerves, I do use a D7000 so am well aware of the p...

think of a digital pentax advice please
I could quite happily use the K-r instead of the K-5, or even the K20D, and we have kept one K20D as back-up. The only reasons for us going for the K-5 were weather sealing and the higher pixel count. If the K-r had been weather sealed I would have chosen that as I rather like the one control whe...

The first 14 in my portfolio on here are all with my KR. The rest are with my KX. You tell me. The KR is a much more capable camera for exposure, focus points,speed of capture etc. the sensor seems to be much the same. low light at high ISO as you can see is brilliant and NR can be adjusted along...

Built in shake reduction. Does this really works?
Do not use shake reduction if using a tripod, monopod or resting on say a wall. As John says make sure the hand symbol is showing steady (as on and ready). Not usually an issue. Use the camera in shutter priority mode and balance highest shutter speed possible with an acceptable ISO. Remember ...

K20D to K-R?
I had the K20D. Loved the camera, but as someone above stated "an enthusiasts camera" I bought a KR and sold the K20D just about an even swap in Dollar terms. Am really happy with the KR, Big LCD, good sharp pictures in any mode, quick to use (I dont have to consider all of the options as I di...

K20D to K-R?
Sorry Stefan, I should have been clearer, it didnt do what it should have done (had it been a Pentax):lol::lol::lol: And incidently, it had a VR70-300 attached and the focus didnt seem any quicker than either my 16-50 or 50-135:D

Catch in focus with K-r
I've just got a new Sigma lens and wanted to try catch in focus, I found the info below but when I try it no picture is taken, any ideas? 1. Menu -> Custom 3 -> Item 20 "Catch in Focus" -> Toggle On. 2. Pop your camera to AF mode. 3. Switch your lens to MF mode if you have an AF/MF lens. 4. Sw...

Catch in focus with K-r
Did you remember to also manually focus on the spot you wanted to take the picture? When the subject arrives at that spot the AF system thiks it's in focus and the shutter should release.

Catch in focus with K-r
Thanks for the quick reply, I've just had another try and got it to work, it doesn't work how I thought it would I thought it would auto focus didn't realise I had to manual focus as well

Catch in focus with K-r
Switch your lens to MF mode if you have an AF/MF lens. As far as I'm aware catch in focus will only work with a non AF lens, when a non AF lens is mounted the AF drive pin on the body mount is pushed back into the camera and disengages, with an AF lens it will still be engaged and trying to focus t...

Catch in focus with K-r
I have a recollection that I've used this with manual focus only lenses by pointing at the subject with shutter down then changing the focus till the shutter fires. (When it has focused)

Catch in focus with K-r
Thanks for raising this topic again Dave, I just checked this with my 50-135 and it does indeed allow the use of catch in focus, unfortunately the MF setting on my Sigma 50-500 doesn't, the motor in the camera body continues to operate, it would be interesting to know if any of the newer third party...

Catch in focus with K-r
it would be interesting to know if any of the newer third party lenses will work if set to MF. Just tried it on my Sigma 50-150mm HSM and it works fine, not so with my Sigma 70-200mm f2.8 or non OS 50-500mm. Guessing it's only HSM models for Sigma ... no doubt a 150-500mm or 50-500mm OS user can ...

Catch in focus with K-r
yeah tried that on k7 with mf 50mm, everytime it takes photo it is out of focus, so maybe needs micro adjustments to AF?
