I use the LED Lenser to aid AF in very dark conditions, such as underground tunnels that are hardly lit. But the exposure is always available light, with a tripod of course.

You could "paint with light" using an LED torch.

Just apply some minus exposure compensation to the K-5 shots and you should be fine. The K10D under-exposes compared to the K-5, or, conversely, the K-5 over-exposes compared to the K10D.

No, of course the logic didn't run like that, OP.

Would there really be any joy in having a situation where Pentax made, for example, a cheap 50mm lens? I mention this because quite often posters ignore that the price of the Pentax FA 50mm is pretty close, sometimes higher sometimes lower, than the better Nikon and Canons that it competes with.

As for the 50mm f/1.8 DA lens, it happens to be one of the best around if any marque.

The 70mm f/2.4 by the way is also a fantastic lens, a very nice replacement for the 100mm f/2.8 M lens I used to enjoy using on film.

The adverts are outside the direct control of Pentax User.

Generally I would say no border, because we want to see the image, not what it's mounted on. For the same reason purple or red mount boards don't help a print much. I've seen both.

Having said that, I've also, very rarely, seen a print on a very light lavender board where the whole was enhanced. The photographer had a rare and special talent for the subtle and for knowing just when to do something a bit unusual.

There are also some instances, usually vintage-style images, where a border is actually needed to complete the whole.

Exceptions often prove the rule.

If there's one with any EXIF that doesn't say August 2013 we'll catch up with it in due course, on our next sweep....

Another removed, please take care that images are shot in August 2013.

Unfortunately a translation for those who do0n't speak German may be needed, or at least a summary of what that thread is about please.

There are different levels of understanding. I know what I like is the first level, after which we can start to wonder why I like what I like, what different things that I like have in common for example. This leads us to drawing up conclusions as compositional "rules" perhaps. So we learn that the centre of a frame is not usually the best place for a subject.

Then there's knowledge about art and this might be the coding in a religious painting. Yes, I know if I like it but do I know and understand how it has been arranged and codified?

I'm sure most of us realise that there's much more to art than just the like it/don't like it response.

Probably different resolutions and if the display resolution is low enough it might not show anything.

As I've said before, I haven't seen any significant moire effects with any non-AA camera. Not so far anyway.

How many MP is the camera - this may also be relevant.
