I presume this is equally good on the K5IIs?

Time is not really the issue here. I find it difficult to accurately focus manual lenses on the K20D because the focusing screen is not good for it (although I have actually now installed an LL-60 screen from an old *ist, which is reputedly better for metering with these older lenses, and that may have benefits for focusing as well, but haven't stepped out of the house with it yet). I'm looking for things which will make the focus easier to get right, and that will be a priority for me in choosing a new camera.

I know I have a rudimentary form of Live View on my GX-20, but I've never explored it, as my understanding was that it's not well implemented and not especially useful. Maybe I'll have a play with it anyway.

My main interest is landscape photography and I have a bunch of old manual focus primes I want to use for this purpose. I currently use a Samsung GX-20 (aka K20D) but may be tempted in the not too distant future to go for something more up to date, capable of higher image quality. One thing which interests me is the possibility of using focus peaking to help with the manual focusing, and I note that the K-30 has this whereas the K5 series doesn't. From those who have used focus peaking, how helpful do you think it would be for my requirements? I'm a bit concerned that the benefits might be somewhat outweighed by the requirement to hold the camera at arm's length and peer at the screen with my reading glasses on, and that the visibility might be poor in daylight.

I'm sure you're right. It's just an interesting point for me, though, as most of the time I'm taking landscape photos, typically at f8-f11, and most often with my 28mm M prime lens. I have made the assumption that IQ is better with my primes, but I really need to do a side-by-side comparison with my 18-55mm kit lens, as this would be bang in the middle of its range.

Am I right in thinking that, although the better older primes are more consistent in their image quality than the new zooms, the differences are likely to be much less marked when you're away from the edges of the range, both in terms of zoom and aperture? For example, a 55mm prime (does one exist?) would be markedly better than the 18-55mm kit lens at 55mm, but the difference between a 35mm prime and the 18-55mm used at 35mm would be rather less, perhaps not really noticeable if you're shooting at f8-f11? Put another way, if you're using the 18-55mm kit lens, you'll get pretty good quality as long as you stick from say 22mm to 50mm, and between f5.6/f8 and f16?

This is a question, by the way, it's not based on observations I myself have made, although the reviews I've seen of the kit lens tend to lead me to this conclusion.

Interesting discussion. I've just got my first print back from DSCL and it's much better quality than any of my attempts from my Canon MP630 (admittedly not a specialist photo printer but nonetheless very well reviewed when it came out). There's an immense amount of faffing about to get things right when printing at home, to do with matching paper, printer, inks, etc., etc. I'm going to persevere for a while until I am sure I can't get things any better and at that point make a decision about home vs lab. Certainly the cost savings are not compelling (at least not if I cost my own time at anything above slave labour rates).

kh1234567890, interested to see from one of your images on Flickr ('Simon Bridge') that you're doing stitching. That's something I'm planning to explore myself, with a view to enabling larger prints. Have you had any really high resolution images printed by DSCL,and if so, with what results?

Thanks! I see DSCL offer 3 different paper types, Lustre, Gloss and Pearl. Which have you tended to go for?

I take predominantly landscape photos with my SLRs, and although I usually just view them on screen, I've had a few recently which I think would work well as decent sized (A3 or thereabouts) prints. Has anyone got any recommendations for online printing services for this kind of work? There are thousands of places out there which offer such a service, but I don't know which ones are any good.
