Thanks for the input. Mongoose, Very funny. That's my feeling though, I don't trust the set infinity on any lens and my mirror lens is designed to go past it. I would just like to see the correct focus with my own eyes. Brownargus, I have the fresnal screen in my old Yashica SLR and think it's...

This cross-links with another thread... the MX/LX had a wide variety of screens for different purposes/lenses etc. That is one thing that could be done! There are always good excuses for a second body.... :D :D :D

Need input from manual focus lens users.
I bought a cheap split image with microprism collar from China via ebay and it works very well. At 200mm you have to have your eye very precisely centred. It is worth remembering that when Pentax fitted these screens to cameras we were warned about their usability. I have forgotten the exact para...

Need input from manual focus lens users.
I make my own split screens from ME Super and Yashica FX3 screens. I use the O-ME53 for close work. I use a DK21M 2X eyepiece for astro work. And this is with both my DS and K200D. I was just using a split screen last night with my 1200mm scope. As long as my eye was centered, the split did not ...

Thanks for the input. Thoughton and Brownargus, what's your feeling on the 1.2x magnifier, is it something you can leave on or do you use it for specific shoots. I was thinking of getting a higher magnification flip up type so as to nail the focus in the center area when necessary. I use th...

Heres link to Katzeye Focussing Screens, They Claim that their horizontal Split overcomes the shortcomings of a diagonal split, Though i doubt if it would help in Astrophotography it would almost certaily be of help with a long lens. I`m certainly considering one. Regards - Pete I love my Katz ...

Need input from manual focus lens users.
Any exposure problems using these screens? Does it meter the same as the pentax screen? With any newer lens A;F;FA and onwards, the metering is fine. With the older lenses M and K it suffers from the same problems as the K10/K20. However spot metering is affected with all lenses.

Thanks for the input. Womble, Good point on the screens that were available. I remember the OM cameras had similar selections and I believe that for extra long lenses and astrophotography, they offered a ... plain ground screen. I'll check on the previous Pentax offerings. Gartmore and Greyhou...

I use live view function to help me with manual focus. turn to live view and 8x magnification. It gives the most accurate focusing (when you see a lot of aliasing on the screen). It is much slower than a split screen though but works fine with me. :D

Thanks Lars. When you get out there with the long lenses, you have to get the habit of having your eye centered.

K-x ISO 1600 shots
Perhaps Pentax will move back to Sony sensors for a K7 upgrade? strangely, Sony's full frame cameras get a bad press for sensor noise.

Pentax *ist D S dslr
Unlike the newer dSLRs, the *ist-DS can support regular (older) TTL flashguns as well as the newer P-TTL :D So you can use pretty well any dedicated flash on the *ist-D and *ist-DS ;) Lenses - nearly any manual focus or autofocus lens. Manual focus lenses that have an "A" setting on the apertur...

Hey everyone, im new on here and need some advice on the *ist d s camera, i.e lenses tht will fit and flashes, remote control, and any adapters that i could use. Welcome aboard.

What do you think about this shop?
Got it now. Forgot about the new numbers actually. I have indeed come across some numbers like that, very rare but have definitely seen it. And also I had forgotten 020 8 is greater London, well at least the majority of them anyway. And usually we associate London inner numbers with 020 and then 7,...

How waterproof is a K10/20D?
I was chatting to a friend who also has a K20D and she told me that it can be dunked in a bucket of water and still be fine as long as you have the waterproof sealed lenses on, not that she has tried it yet.! I am interested, as a few weeks back I was photographing some surfing event and really w...

How waterproof is a K10/20D?
My K20 has been in a puddle on it's back the water did not reach the lens mount and it is none the worse for wear, would like to add this was a misshape and not an experiment.

How waterproof is a K10/20D?
My K10 has been through a few storms and withstanded waterfall sprays, but you have to wipe the camera dry asap, mind you, without a weather resistant lense i.e. DA 16-50mm, your front end is comprised. Back to the bucket story though,....come on.......do you really want to duck your poor little cam...
