Focusing Screens
The problem is that with an f/1.2 lens you see through the viewfinder the DOF of an f/2.6 (approx) lens, so because you can only focus within the DOF of f/2.6 it might be outside of the DOF of the f/1.2. Some bits that look in focus through the camera won't be in the actual shot :shock: How come...

I think the confusion here may be one of nomenclature, or how it's being described. Clearly we can't see more or less DOF than actually exists, but there is a limit to what the eye can differentiate. Even a 35mm viewfinder is too small to accurately assess DOF in a shot. What looks sharp at 36x24...

Even Nikon don't do a screen for f/1.2 f/1.4 See halfway down this page: http://www.kenrockwell.com/nikon/50mm-f12.htm - And in that article he actually mentions that canon do make a screen for lenses great than 2.8 And that's where the EE-S screen is recommended and of course why the...

Having read all the threads in the other place about focusing screens I was hoping for a further reasoned debate in this house. Some pertinent comments have been raised thus far, as have some others that have indirectly led me towards a greater understanding of my enduring problem. Namely capturing...

I don't have a f/1.2 lens, but I can focus my SMC-A 50mm f/1.7 quite accurately fully open using the KatzEye screen. My main reason for buying a KatzEye was that I was using a 300mm zoom, sometimes fully open at the long end, and had problems focusing manually - plus having grown up with an old ful...

..... having grown up with an old fully manual film SLR I expect to see a split prism when I look through the viewfinder! Has anyone tried a KatzEye screen at f/1.2, and does it work? I cut down an ME split prism for my K100D years ago and loved how useful it was. Only downside apart from meter...

K5 battery
:? sounds pretty good, 7 hours constant monitoring focus points, processing on mini computer, every two minutes, stop down the lens, slap the mirror, write to cache, process, store in cache, write to memory card, run the metering ... anything else? All from a battery less than 2000mAh You get ma...

K5 battery
My second battery which i mainly use in the grip lasts a bit less than the other. But that's because it is transferred from my k7 and is 3years old. Still i am able to take like 1500 pics with two batteries, so no complains :) I rarely do such amounts in one shooting. When both batteries were fresh...

K5 battery
Batteries ,I have a set of Eneloops in my K100 and they work fine maybe 300 shots per charge I have a set of energizers for emergency they are two years old ,they live in the bag and still read fully charged if I stick em in the camera . When I use my longest lens 80 -320 I use manual focus first ...

Which one?
You can make superb photos with a K7, you really really can. I've only felt held back a few times with one (the forced dfs in startrails and underexposure noise). And at £300 that's a bargain for a rock solid piece of kit. But it slightly depends on what sort of photography you do, if high ISO stuff...

K5 sharpness settings
Out-of-camera sharpening techniques aside, this is a fairly poor subject image with which to compare the sharpness levels. It basically has one and only one in-focus contrast transition that sharpening would do anything much with. Hopeless, really. You really need something with a lot more de...

What's your favourite Pentax DSLR?
K10D for me so far :D I have the K10D - I am thinking of an upgrade nearer September (birthday time) - BUT after paying the balance on our holiday, buying the new Liverpool kit for my lad plus new trainers for both of us I decided yesterday having already spent more then a K5 would cost I would p...

What's your favourite Pentax DSLR?
K200D for its ergonomics, K-r for it's ease of use, K5 for performance All great in their own way but - I would have to go with my K100D as it was the camera that got me back in to real photography in a big way having languished in the Canon/ Nikon point and shoot camp for 10 years! Carl

Loved the GX10 for its ergonomics and build quality, but the K5 with its faster auto focus superb ISO capability's and faster frame rate combined with a grip make it superb bit of kit.

What's your favourite Pentax DSLR?
I've only had two, and use the K5 predominantly. However, I am always pleasantly surprised when I occasionally use my K-x. Its a basic dslr. Miles behind the K5 and K-r Hasn't even got focus point verification, etc, etc. Thing is, it takes cracking pictures. If it wasn't so good I would have went ba...

I'm just back from Greece with my new K5 that replaced my KR. The K5 is quite superb and vastly more usable. It is heavier than the KR but barely any difference size wise in your hand. The autofocus, metering and quietness along with the brilliant TAV mode and its tweaks are superb. Very usable ...

What's your favourite Pentax DSLR?
The K5 is the best camera I've ever owned, film or digital, although back in the 1980s I really loved the MX. I also had a superb ME Super and had use of a Nikon FM2 for work purposes. The FM2 had similar spec to the ME Super but I vastly preferred the Pentax because of its superior ergonomics. Bac...
