Don't forget PU's sister site www.photodo.com which has thousands of lens reviews.

Requirements can be very different and if you are looking for a simple way to store web sized images, then the tools are there in Photobucket, Flikr and so on to resize. This is not the way to optimum quality for print, but if it's all you want then you could set a smaller file size in the camera and shoot at a reduced MP count.

It becomes very different if the best quality images are involved, because then we want the largest file size and perhaps the best way to store a bulk of these is to use external hard drives. Always keep more than one copy to cover for hardware failures.

Professional standard resizing for a specific purpose is best done is programs such as Photoshop.

I thought it was interesting and it was the first time I'd noticed it.

It's also interesting that a while ago there was sufficient interest and confidence in the Q for someone to produce such a lens. It seems it may have been a short production run, but I hope they did well and sold them all. Probably in Japan?

I'd like to try this for myself yet, because I don't know how the K-5 II image with suitable Photoshop sharpening will compare against the K-5 IIs with also whatever the appropriate sharpening (if any) is needed.

As with using different speeds of film though, it's not so much that any extra details are extracted from the subject (on a normal visual level rather than under a microscope) but that the same detail is recorded with crisper outline and higher contrast.

The behaviour of the human eye is such that the actual effect on the images overall has yet to be properly explored.

He probably thought you meant K-5, which has of course been replaced by the new models.

Often, it's an excellent discipline to do this with various lenses. It makes us really see things and work at it.

Try it with all lenses, even a fisheye or a long telephoto.

WR lenses are weather esistant, so away we go in the rain. Some lenses have SP coating as well, which repels water and is even better in the rain.

As regards clewaning, as little as possible is best. A microfibre cloth will do the job and lens cleaning fluid is rarely needed. When it is used, it should be sparingly applied to the cloth, not the lens.

Older manual focus lenses will only support limited features, so centre point focua is, I think, normal.

There are many features in cameras these days that help beginners, but actually to use will slow us down if we know what we are doing already. I find the idea of wasting time selecting a focus point a bit bizarre when we can focus, reframe and shoot far faster.

Although it's not the professional way to do food photography, at least the pictures produced with authentically show exactly what is on offer.

It's not a great idea to put an e-mail address in a forum, so I've modified it at least, so you don't get spammed.
