Need some help with regards to shooting wide open
I'd love to have a camera that could focus on the rear of the eye. I don't think Pentax or anyone else has made one yet that can do it without being attached to a very good macro lens, if not a microscope,

A camera will focus whatever it is pointing at just because it's an eye makes no difference. I have just measured my eye brow and it's approx 8mm in front of my eye ball. Well withn the depth of field of a 50mm 1.4 lens to get the eye in focus on a regular basis.

I think what was being said here was not that it was the photographer who was specifically focussing on the rear of the eye 'assembly' - but rather that when the photographer tries to focus on the front surface of the eye the focus point ends up in fact at the back of the eye (MattyH's Macula & Folv...

Compact System or Compact camera?
I'd also strongly recommend the MX-1. Aside from good results, including surprisingly good at highish ISOs, the flip out LCD can be very useful for discrete street photography, and the camera is also quite speedy including focus speeds (my experience with Canon G9/10 is that the Pentax is much fast...

Compact System or Compact camera?
I finally got into a camera shop to have a look - sadly, no MX-1s or Ricohs to play with! I did have a try of the Canon Powershot, the viewfinder was as bad as Jon had suggested, utterly dreadful. The Fuji X10 was much, much nicer, but there is some concern over image quality of its RAW files (f...

Testing 17-70 lenses - Sigma vs Pentax
Hi Everyone I recently acquired a Sigma 17-70 F2.8-4 HSM OS Macro lens from another Forum Member, with the intention of keeping either this or my Pentax DA17-70 as my default walkabout lens. However, since getting the Sigma I have struggled to get sharp images from it, so today I decided to cali...

Testing 17-70 lenses - Sigma vs Pentax
Thanks for the comparison -- I'm looking for most consistent sharpness for the buck. If you had to choose, which? That's a really difficult question. I've always found the Pentax DA 17-70 to be a reliable performer, except on my first K-5 on which it didn't focus properly, but that was the camera, ...

Smeggypants wrote "it was indeed a Sigma 17-70 that taught me the lesson to ALWAYS Check focus calibration as soon as you get a new lens and to ignore anyone who says otherwise" As a relative newcomer with a new camera + lenses what is the best way to check focus calibration? Not yet shooting ...

Projector Colour Temperature
You can calibrate a projector using a colormunki too. We did at Oldham CC a month or so back - improved it no end. Andrew

Digital Projector Resolution
We (Oldham CC) used DiCentra for the first time a couple of weeks back. All images were 1400x1050 - but the projector resolution is 1024x768. It worked fine. Andrew

Book recomendation for a skin flint DSLR enthusiast
Why buy a book? Well, for me, I still do buy instructional books because I find I only really absorb and digest the information in that format, and I still enjoy the physicality and 'presence' of a nicely printed book. Its just a better way for me read and see information than on a screen. The l...

Book recomendation for a skin flint DSLR enthusiast
Try your local charity shop. Some seem only to get cooking and gardening books but I've found some good photography books sometimes. Usually I find the local charities, rather than the national ones, seem to get the best selections although Oxfam have special book shops in some towns but they ten...

Lightroom 4 purchase - advice please
I currently use PaintShopPro X4 and Picasa for my (very minimal) processing. PSP has a lot to offer but to be honest I'm not getting on with it that well so tend to not use it very often and fall back to the very simple Picasa package. Many of you trumpet the pros of LightRoom, so having spotted ...

where to view and print the images matching the quality of the K3
I have recently purchased the K3 its a wow! But I do not have the standard of printing equipment or monitor to transpose whats in the camera to either whilst preserving the quality. Is there a studio in London or a shared resource in London that Pentax users go to? Most local print shops are at 8 bi...
