It's possible, but the point I've made elsewhere is that you still end up needing a camera bag because the lenses are quite long, especially lenses for K mount. The result is a camera almost as bulky, but with a thin, fiddly body.

Functionally, I don't see the point, except that people like new bright shiny cameras. And manufacturers need to sell new concepts to keep expanding.

Excellent abstract!

I've disguised you e-mail, but not a great idea to put your mobile number in a public forum. If you want it removed, please let me know.

Trap a wire, crease a seal and you've created more problems that you had to start with.

I wouldn't dream of doing this, back to JPS for my cameras if there's a problem.

I think it would ruin a perfectly good street camera by making it bulky.

It's not the width, it's the depth of the lenses that cause the problem.

It's all very well, but what we end up with is a small fiddly camera body with a huge lens on front that makes the overall volumetric bulk pretty much the same. That is, too big for a pocket, so we still need a camera bag. I don't see any advantages and all the disadvantages.

The K-01 was ideal if you wanted a full quality interchangeable lens camera but not optical viewfinder. Great for small product photography and still life macro and anything else you would use one of the smaller cameras for.

I have handled a K-01 and it works rather well. The small CSCs are a different beast, the only sensible one for me being the Q series.

I think sometimes many of the arguments we see on the web stem from a failure to define the terms we are using. Even, as you say, "easier to use" needs to be defined so we are all thinking about the same thing. We've already thrashed out that "best" can mean many things.

In the context of the quote I was meaning best in terms of quality of manufacture, precision etc. So, for example, the best ruler is the one that's straighter and has more precise markings. It might be metal instead of plastic, it might have finer engraving for superior accuracy. Thus easier to use in that it will be easier to draw a more precise straight line of a given precision.

In this sense, I find the DSLR tends to win for me. It's easier to produce a quality result from a wider range of subject matter. It's not easier to carry than a compact or camera phone, which require much more care to maximise the quality they are capable of.

Good idea, if that's the only difference in what you are doing it might somehow be the culprit.

Thanks, I was wondering if you were talking about vibration from mirror slap, which is something else entirely.

Have you activated the aperture ring in the menus? "Using aperture ring" needs to be set to "permitted". Then the next thing is making sure all electronic contacts are clean, using a soft cloth. Obviously not on a T2 mount, but if it's a metal mount is it shorting out a contact perhaps?

Hope something along these lines might help.
