Sticking to Pentax DSLRs, as you might expect on Pentax User, there's no need as such to upgrade a K-x, unless you feel there is some feature that is now available that would be useful to you. This is quite different to fancying something new, which we all suffer from, from time to time.

The K-x is still capable of producing fine images. Plenty of people still use the K10D or K20D or even older Pentax DSLRs.

Possibly new lenses might be more useful, possibly you just want a new DSLR. If the latter, probably the best you could go for would be a K-5 as it dosappears from the market. Low price, superb quality and adding weather resistance, more MP, and many other features.

Thanks for looking. This shot was ISO 400.

JohnX is right IMHO, problems are exagerrated and the happy majority say very little because they are quite happy.

This is not to say that problems do not exist, but it applies equally to all marques and all price levels.

That's interesting Don, on my monitor I can see detail throughout her face. Perhaps someone else could comment - what do you see?

Do please add EXIF data to those images that do not have it.

Also, another image removed as it was not shot during September, nor was it a Pentax camera. Samsung cameras are also allowed in, but only those that were variations of the Pentax DSLR range.

Hope that helps!

Just look in Classified Ads in this forum and you will find a new I-10 at a price that should suit.

A lens has a coverage that fades gradually as you move from the centre axis, so you get vignetting rather than a sharp cut off.

Depending on how quickly the lens vignettes will dictate what format it is suitable for with adequate coverage. Some high quality lenses will hold their quality enough to use on full frame even if not designed for it, but only if the manufacturer has generously only used part of the available image circle and not cut it off as well with the lens body construction.

Mike's suggestion seems sound. You could add reasonably priced primes such as the 35mm f2.4 and 50mm f1.8 and maybe the D-FA 100mm Macro if budget allowed.

There are really quite a few suitable Pentax lenses, so pretty much anything from the current catalogue will serve very well.

The crop factor is 2x as opposed to 1.5x so images will be noisier and the K-5 beats the E-5 hand down IMHO. Having said that, i do like the E-5 with its 12-60mm lens, but I wouldn't buy one. You can look at my EPZ reviews of both these cameras.

You just need Pentax lenses and you'll be fine. Even the kit lenses will not discredit pentax in comparision to the Olympus lenses you mention, but if you do want a higher grade of lens then look to the more expensive Pentax zooms and the Pentax primes.

You will not be disappointed, and I suspect you will be pleasantly surprised at how much better the colour and white balance are with Pentax. There is a reason I've stuck with Pentax over the years, and it's certainly not a financial one, it's all about image quality.

In that case, I'd switch off SR. In any event, say using a 100mm lens (550mm 35mm-equiv) at these sort of focal lengths I would be looking for some sort of camera support.

Usually I use a tripod with the head loeft loosish so it can be freely turned whilst retaining some measure of support.

I'll look forward to trying out an adapter so I can have a play with various techniques.
