21mm Limited Back Focus Issue
Interesting stuff Ben. Out of interest, have you tried the SMC-FA 50/f1.4 yet? Maybe a little on the long side for your uses, but it's a lens that never disappoints me with beautiful bokeh and stunning sharpness. I'd be most interested in knowing how the new 16-50 compares against both the 16-45 ...

21mm Limited Back Focus Issue
Ben, Thanks for the comments. Unlike you I rarely have strobes set up, and usually shoot with available light :) Out of interest, just how many lights do you use?? Matt

Ben, Thanks for the comments. Unlike you I rarely have strobes set up, and usually shoot with available light :) Out of interest, just how many lights do you use?? Matt Hello Matt; It really depends on the shoot. On average about two to five heads. But that is not important in some of my lig...

21mm Limited Back Focus Issue
Hi Ben, Thanks for that - it makes sense. You've got an amazing control over the light! So... do we get to see the results of the simple setup as well?! Hope so ;) Thanks! Matt

21mm Limited Back Focus Issue
Just got the response from Pentax via their head office in Germany. They confirmed that there is a back focussing problem with the 21mm Limited exclusively. What exactly did they confirm? That there is a BF problem with your lens or with the DA21 in general? I shoot a lot with the DA21/K10 and ...

Wide angle zoom - recommendations
Thanks for the prompt response. I am still a little confused though - you say the Motor is mounted in the body yet the latest lenses from Pentax will have supersonic motors, how will that work? Will this make the focus response quicker I assume. I already have the standard 18-55 lens and surpr...

Wide angle zoom - recommendations
Keith, The new lenses will have internal motors that will work with the K10D only. (For all other bodies these new lenses can be driven by the body motor.) It's supposed to be (a) quicker, (b) quieter. But we'll have to wait and see :P Having said that, the K10D has probably the fastest focu...

Wide angle zoom - recommendations
I sent an email to Sigma UK a couple of weeks ago asking if there were any plans in the works to start making HSM lenses in Pentax mount. They said they hadn't heared anything about it. Since Sigma usually reverse engineer things I imagine we'll have to wait a while after the DA* lenses hit the s...

Pentax low competition Nikon D40x revealed
The problem with cramming a lot of pixels onto a chip is noise. As I understand it you start to get leakage from adjoining pixels, from (I think) quantum effects. Oh and reading all that information off the chip in a timely manner. OK, the 2 problems are..... There was a discussion at DP revie...

Pentax low competition Nikon D40x revealed
John, Agreed, there one bloke at my local "J" who's really hot on all aspects of photography. He suggested I buy a pentax when I got my first SLR back in '96. What I actually meant to imply was that the average first-time purchaser of a DSLR was unlikely to ask too many probing qu...

Split Image Focusing Screen for K10D
My new split image screen has turned up :D Scary moments taking the old one out but the wife's padded craft tweesers did the job :wink: Fiddly but i's now in place and working great - exposures are fine, auto focus is faster and manual focus is much easier and faster :D :D :D Highly re...

Split Image Focusing Screen for K10D
As Mongoose says it shouldn't make any difference to focusing speed but it does! Someone somewhere will probably know why. It cost £18 inc delivery from e-bay :wink: http://cgi.ebay.co.uk/New-Split-Image-Focus-Screen-Pentax-ist-D-DL-K10D_W0QQitemZ320092848996QQcategoryZ50508QQrdZ1QQcmdZViewIte...

Split Image Focusing Screen for K10D
Absolute doddle to fit :D even for my clumsy hands :lol: It looks just like the katz eye as well - but doesn't have the little tag at the bottom. 1. Take the lens off 2. At the top centre front under the penta prism there is a silver coloured latch - hold the camera upright and pull latch t...

Split Image Focusing Screen for K10D
If you're using MF all the time then why not - after all its not like the price of a Katzeye :wink: and you've still got the original should you need it. Can't see me changing back now though :D

Split Image Focusing Screen for K10D
Would this work with a mirror lens? Does it work with Macro? Is it as accurate as the auto-focus? Cheers graham

Split Image Focusing Screen for K10D
Just tried it on a friends 500mm mirror (non AF) and it give far better focus accuracy than the original screen :D Macro is fine Just as accurate as auto focus in my mind as you have total control over the focus point when in manual focus mode. Auto focus often selects the wrong focus spot f...

Split Image Focusing Screen for K10D
"........Is it as accurate as the auto-focus? ..." No!.....it's about a hundred times better!! The fact is that manual focus using a split image rangefinder is THE most accurate method of focussing a SLR type camera. When you are practised at it it is also virtualy as fast as AF an...

Split Image Focusing Screen for K10D
HGi The fact is that manual focus using a split image rangefinder is THE most accurate method of focussing a SLR type camera. When you are practised at it it is also virtualy as fast as AF and frequently faster. My first real camera (ie not a box camera) was a Minolta nearly 45 years ago with a s...
