K5d or D300s
I've been comparing the two Dslr Dpreview in and saw that the D300s, has no great advantage in the K5 To be honest I wouldn't believe anything written in a DP review, even if it said the K5 was better than the D300, my Son called round today with his recently acquired compact (a Fuji EXR600) the DP ...

K5d or D300s
As for focus reliability I have sat amongst both Canon and Nikon users in bird hides and heard their curses as their lenses fail to lock on to the subject and they miss the shot, and they've heard mine when the K5 fails to lock on. Knowing both your subject and your equipment and also how to use i...

K5d or D300s
Have you tried shooting in Shutter priority mode rather than Focus priority mode when birding ? The focus lock will still beep when you hit focus, however if you have to take the shot before confirmation you will still get some sort of shot and it may well be in-focus I might give it a try, but will...

K5d or D300s
I only use centre point on the K5 as it is, 51 would be just another 50 chances for the camera to select the one I don't want:lol: I don't think we should rule out other systems being more reliable in terms of selecting the correct focus point :smile: Although I must admit it's a moot issue for me, ...

K5d or D300s
It is not good and lenses are so slooowww ;). There are specific situations where tools in use really must be up to the challenge/work. Just try to imagine someone with current Pentax DSLR and DA*60-250mm i.e at Mach Loop, trying to catch something in focus, some Mach Loop examples: http://www.ai...

K5d or D300s
I've found that all the AF bodies I've tried from all manufacturers lock on and focus fast enough. Ironically, the slowest was the Nikon D300S, but maybe it was the lens itself that didn't help.

K5d or D300s
It was a serious question. How do they help? How do you use the system correctly? It's a good question. If I was doing a thought experiment, I might imagine that the camera was clever enough to notice the subject tracking across the AF points, as its distance from the camera changes. Then it...

GX 20 problem
I took a few pictures tonight on my GX20 and noticed a thin black line running from left to right halfway up the image. Is this a faulty sensor? Has anyone else experienced this. I've half a mind to send it back to Samsung as I would expect a camera to last more than 2.5 years with only about 7000 c...

Focusing Screen for K-r. Any recommendations?
My K-r is great but I find that I'm missing the large bright viewfinder of my SLR, and most especially the split focussing ring in the centre. Yes, the autofocus is a handy feature that I do use a lot now, but it occasionally struggles so I do like to check and I do make fine adjustments with the q...

Focusing Screen for K-r. Any recommendations?
There hasn't been a split image focusing screen since AF arrived. It upsets AF so what would be the point? Admittedly it will depend very much on individuals' eyesight, but I can easily focus using the ground glass screens. In fact, I always did, even when microprisms and split images were availa...

Focusing Screen for K-r. Any recommendations?
I've had split screens fitted in both my K10D and my K20D without any impact on the AF whatsoever. I managed to get a katzeye split screen second hand and have never looked back. Best thing I ever bought to go with the camera. Much more useful than, say, the grip which I never use. K.

Focusing Screen for K-r. Any recommendations?
Hi, I have A Kr too and it's the cheap Pentamirror that gives less light than a prism as well as the smaller sensor format. I've had screen out for cleaning on a KX and now my KR when dust gets above the screen. Don't know why they classify them as not changeable as they clearly are, albeit wi...

Focusing Screen for K-r. Any recommendations?
I'm not getting this John. I thought the Af system resided in the base of the body and not in line with the focus screen or prism. Am I wrong?

Focusing Screen for K-r. Any recommendations?
Figure 3. A phase detection AF system uses a series of mirrors, a small sensor at the bottom of the camera and a processor to calculate precise focus. AF system Photographers are used to trusting auto-focus — even on action shots where the shooter is following a moving subject. When a DSLR's...

Focusing Screen for K-r. Any recommendations?
Johnha - according to the Katzeye blurb I read yesterday on their site the blackout problem we all remember from SLR days does not occur with their DSLR screens. Something to do with the different focussing arrangement. I'll have to go back and find the exact info on that.

Focusing Screen for K-r. Any recommendations?
Spaceman - I think you can minimise it, but only by reducing the accuracy of the split-image. If I remember correctly pro SLRs used to offer different screens for different light levels but with reduced focus accuracy (unless I'm mistaking the micro-prism ring around the split-image)?

Focusing Screen for K-r. Any recommendations?
These are recut canon ee-s screens. is the one I have. I can't really vouch for the other screens but metering seems to remain fairly accurate with this screen at wide and not so wide apertures. There was talk of failed center spot focus with split screens earlier. I think this was a confus...

Focusing Screen for K-r. Any recommendations?
There was talk of failed center spot focus with split screens earlier. I think this was a confusion, split screens tend to totally mess up spot metering, not focusing. If you like the FSL then maybe the K3 would suit you. It's not 45° though. I have had a K3 model for my K20D and I have been very...

A bit of a resurrection required here folks on this thread ... I need to know what a "Dual 45 degrees split image focus screen" will give me in the viewfinder.

Focusing Screen for K-r. Any recommendations?
I've got one of those cheap Chinese split screens for my K100D Super.Easy to fit and works great - and the auto focus bleep confirms when things are in focus with the split screen focus - helps focus the manual 50mm 1.7 and 135mm 3.5 lens that I have. The microprism ring helps too! Auto focus still ...
