DA* 50-135mm 2.8
Hi guys, I'm thinking about buying the DA* 2.8 50-135mm zoom for my K10D. Can anyone tell me how the "instant" switch from auto to manual focus works? Mike

If it works like other DA lenses, with the lens set to AF you simply turn the focus ring to focus manually. So if the camera thinks it's focused, but you can see it's not, a quick turn of the focus ring sorts it out. No need to switch between AF and MF. Dan

DA* 50-135mm 2.8
using either af/mf switch to mf though will allow you to shoot even when out of focus.

DA* 50-135mm 2.8
Yes, but I would have thought that the "instant" switch to MF refered to was the one I mentioned. And, as long as the camera has 'focused', and you've kept the shutter release half-pressed, I believe it will fire even if you then unfocus it (assuming you want to spend £500 on a lens with ...

DA* 50-135mm 2.8
The lens AF/MF switch works just the same as the body AF/MF switch, having the switch on the lens lets you toggle between AF/MF without having to let go of the lens zoom ring, the lens setting overrides the body setting.[> Total bollocks :oops: having spent the morning rechecking what I wrote a...

DA* 50-135mm 2.8
Hi Dan I agree with your statement, I just didn't write it very well. What I was alluding to this morning was that I thought that if the body was set to MF and the lens set to AF the lens would still AF when you half pressed the shutter button or use the dedicated AF button, this is of course ...

The quick shift wouldn't be any use in this respect, as the AF has to lock on first, This is only true if you have the focus with half press set to ON, I have this set to OFF and use the dedicated AF button set to ENABLE, you can then release the shutter without having to be in focus.

A closer look at Shake Reduction on the K10D
You may remember that I threatened to do a bit more of a careful investigation into the allegation that shake reduction on the K10D causes shake when the camera is still. Well I have, and the results are in. For those that just want the bottom line: - If you want to eliminate shake on a tri...

A closer look at Shake Reduction on the K10D
my method of polling a larger sample will produce more accurate results than your method of using a tripod, to find out if a steady handed shooter without tripod is getting adverse results. Well, this is true if whatever you do, also excludes other reasons someone might get better results without ...

A closer look at Shake Reduction on the K10D
My original post was in fact a question based on an observation that I wanted to verify. Not a proclimation of scientific discovery. But thank you for your time and effort! I do appreciate it. until I hear others ring in with thier input, I'm done with this. You did an amazing job with the testi...

A closer look at Shake Reduction on the K10D
if it doesn't provide a clear advantage, where I reach my limits, then I lose nothing by turning it off. Yep, no argument there. ps ChrisA said: [quote:8060fef1ca]You absolutely, definitely, will not cause any damage to the camera by leaving SR on. (advice against manufacturers warning) ...

Cleaning behind the focus screen.
Like an idiot I purchased a split focus screen for my K10D to aid manual focus macro stuff and it was basically a load of rubbish so I put back the original. I now have half a ton of dust behind the screen and a ruddy great fingerprint on the screen itself (sigh). So anyway, I am going to buy my...

Cleaning behind the focus screen.
The Arctic Butterfly is designed for sensors, but is actually good for the focusing screen and prism as well. An ordinary camera brush might be enough, though. Katzeye make excellent screens for manual focusing.

Cleaning behind the focus screen.
Hi, Cleaning behind the focus screen is realy easy... (although when I had dirt behind the focus screen of my DS it took some time for me to suss how to do it) You already know how to take the screen out so just pop it out and blow with our blower. While its outs out use some sensor cleaning s...

Cleaning behind the focus screen.
I sent an email to Pentax UK and they quoted me a price of £25 plus return postage and VAT to clean it. I thought that was quite reasonable actually.

Cleaning behind the focus screen.
Hi I don't agree - I think £25 + postage is a lot for what is likely to take you just a few minutes given that you know how to remove and replace the focus screen, you already have a rocket blower, and you have a brush on the way AND you aleady intend to buy a new screen what can you lose by ...

Cleaning behind the focus screen.
It may be reasonable for Pentax to charge £25, but I agree with Mr Bob that it's not worth it when you can DIY. Total postage would cost over a tenner, and you'll be without the camera for a while.

Cleaning behind the focus screen.
you really have no idea how bad the dust really is do you, when I say bad, I mean BAD as in dust and little black hairs right in all corners of the viewfinder where I have pushed it while trying to clean. I will wait for my brush to arrive first though, just to see if it can do a reasonable job.
