Can't get a manual exposure
I agree on all the above, great advice there . How much of the frame is taken up with the lamp? If it is very small, surrounded by lots of black space, then you are probably taking too long an exposure anyway, and will just end up with a blown-out white spot. Can you zoom in and fill a good bit ...

Print sizes
The image produced assuming no cropping is 4928 x 3624... purists reckon at 300pixels per inch you would get top quality print at 16 x 12 inches which is roughly A3. However depending on viewing distance you could go larger... If you print at 150 pixels you would get 32 x 24 which is A1 and but to g...

Practical Photography KS2 Review
I agree, I tend to make choices on whether I just like something; it's a better system than endlessly poring over reviews because there will always be a new model which on paper is better at this or that and so far this system hasn't let me down. I used to think I would like a Nikon until I picked o...

Practical Photography KS2 Review
I subscribe to this mag and sent a really long mail to the editor about why I would not be renewing and lo and behold they then review a Pentax camera 2 issues later.. And boy have they slated it. Having used the camera for some time it was like reading a review of a different camera! Can't sa...

Very interesting article for those who are Pentax and believe in Pentax
Interesting to some degree in that the astrotracing ability has been there for a very long time now, IF you purchased the dongle, which is the same issue they knock Nikon for charging extra for, which is what Pentax had done for a long time too. The only big change here is it's now built in, which ...

Edit: I think the 4.5 stops in body stabilisation is a pretty killer feature Brings us back on a par with the Sony A7ii ability, oh and Olympus em5 mkii also.

Very interesting article for those who are Pentax and believe in Pentax
The Pentax focus thing is interesting. I suppose it depends on what you're photographing but I went to Derbyshire and Staffordshire at the weekend and took an embarrassingly large number of pictures, most in dim light, some of which featured moving objects and people. None were out of focus. Non...

Very interesting article for those who are Pentax and believe in Pentax
There's often this gap in experience Andrew; I totally agree with you, I never have a focusing problem either. But then I don't use tracking focusing for moving subjects - I still use centre point only and if I think it will be difficult I go back to manual focus, so for motor sports for example...

Good point John. Having said that though, even with any camera/ lens focus is very subjective. I know many photographers that will sit there any study I photo and argue whether it's in focus or not

Very interesting article for those who are Pentax and believe in Pentax
The K-5ii cameras onwards are demons at focussing in dim light, without the need for a focus assist lamp. Like John, I don't use focus tracking and I stick to centre point, but unlike John I have had focus issues, more so with certain lenses, such as the DA 17-70 and surprisingly the DA*50-135, whi...

K5 AF issue resolved
The crazy thing is I have been blaming my lenses and doubting myself over the last few years. I really thought that my photography was going down hill and have started to loose the passion. It just shows you how God damn important neat focus is

Ricoh AF Patent
I had a look at the picture in the original link and think I understand what is being proposed. In a traditional autofocus system, the light enters, and some passes through the primary mirror, is reflected of the secondary mirror and down into the autofocus assembly. I believe the secondary mirro...
