K5II choice considerations - a new take
There's a logic to what you say about the additional, inherent, extra 'resolving' ability of the 's'. What this testing is telling me though is that you will only get a consistent practical benefit under certain conditions - there are variables of subject type, processing styles and the intended...

K5II choice considerations - a new take
Chris the k-5 is nit being compared here. There us a huge difference in iq between the original mki and the mkii bodies. There is however very little difference between the mkii bodies. this test is excellent and proved what i have thought all along �� Ok, thanks for the reply, that...

K5II choice considerations - a new take
I personally am a gut feeling shooter so wouldn't have the tenacity for such analysis, but I also recognise and respect the passion for objectivity on such matters that you've taken the time to document with such detail. Of course, that's your shooting style, and I would advise anyone to take their...

K5II choice considerations - a new take
Which of my 4 result categories would you put you own style and processing approach into ? .... 1) Definitely not - no jpegs here. 2) Definitely not - no PDCU here either. 3) Sort of - although I don't usually do that large a print size. Nor do I usually sharpen to extremes either. 4) Sort of ...

K5IIS V CANON 6D
Apparently you actually have to own the cameras in question before being qualified to make judgement. Gulp. Not own, but at least try for yourself. There's a very good reason for this, basically you don't know what limitations there were on the shots published. If you do it yourself you do. In ad...

K5IIS V CANON 6D
But you can't argue it both ways, on the one hand saying that reviews are not to br trusted and on the other that they are scrupulously undertaken. The politically correct thing is a total red herring as it doesn't exist. Still, no point in going over the same ground time after time. I now ha...

I want to try Macro
Thanks for the help so far. I was looking at the Raynox DCR250 adaptor as I thought it could be used with my existing lenses. Would it be a good starting point. Thanks Les Possibly, depending on the filter-thread size of your lenses... Actually, the F-35-70 is not a bad idea anyway as it...

I want to try Macro
While not truly "macro", the kit 18-55 focuses surprisingly close and actually gives better magnification than a fair few "macro" zooms. That's a very easy starting point for flowers and bigger things like that. You could couple that with a close-up filter for a very cheap set up to see if macro is ...

K-3 ?
I'm ready to place my bet. It is going to be a K5mkIII, a 24mp sensor being the only difference. I also suspect they won't even release a version with a AA filter this time. I'll also add 'No FF' to the accumulator is pressed.

K5 soft focus, poor colour contrast and detail
Re the colour and contrast, have you tried a different picture setting or adjusted the contrast / colour in the one you are using? It could be that the K5 has a different look in 'Natural'. Have you got highlight/shadow compensation on? Those will reduce contrast. I've applied some curves and ...

K5 2S moire-Just for the record
Incidentally, using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire.

K5 2S moire-Just for the record
Incidentally, using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire. I am a bit astonished to read this. See e.g. http://www.dpreview.com/previews/ricoh-gr/9 - "Ricoh GR - F2.8, 100% center crop" (http://4.static.img-dpreview.com/previews/rico...

K5 2S moire-Just for the record
In what way are you astonished? It might be questionable whether or not color moiré is a problem for most pictures. However, it also might be disputable whether the absence of an AA filter really is desirable (an advantage). But this is not my point. Knowing you as an expert and experienced "test...

K5 2S moire-Just for the record
I suspect that you can find moire in images from many digital cameras even if they do have an AA filter - if you look hard enough. This is a small crop from an image taken by a K200D with a 18-55mm kit lens. Andrew

K5 2S moire-Just for the record
When I did my comparison tests (K5II vs 's') there was one small item that was completely swamped in moire effect on the 's' image, and the 'non-s' version had none of it at all - a clear difference on a small item with a ribbed & repeated texture. This was the effect of the aa filter removal. I...

K5 2S moire-Just for the record
I think it's time this subject was closed. It's well covered on more technical forums and blogs for anyone who is interested. Incidentally the Pentax K100D had a very weak anti-alias filter and suffered badly from moire..... nice example . --

using the GR, which has the same size sensor and also no AA filter, there has been no sign at all of moire I currently test a Ricoh GR from Pentax/Ricoh Germany. As the weather is not really good here, I also have looked at color moiré. Imho, it was quite easy to provoke problems: https://www.pen...

Thoughts on camera for Alaska?
Make sure you have "filters" on all of the lenses and a protector on the LCD. Yes, lenses might be water resistant but a "Protector Filter" will stop splashes on the front drying and leaving salt marks and you can be a little more confident about wiping them off. You will find the LCD screen m...
