Old 50mm Macro

Anyone used one of the 50mm manual macros on the Q? If so what were the results?

Here are a couple of shots. Not the/an old macro, though: this is with a SMC Pentax-FA 50mm F2.8 Macro with a touch of fungus inside, and the genuine Pentax Adapter Q for K-Mount Lens. I doubt which lens makes much difference.

These are the full Q7 frame images (4000x3000, reduced to 1280 wide in Photoshop Elements to fit Forum rules - and probably reduced further for actual posting).

Here are 1 mm marks on a ruler, so the total frame width at maximum macro is a bit more than 7 mm wide



And here's a zoom in on a really small bolt (seems too grandiose a term for something so small, but technically, I wouldn't call this a screw!) that is about 3mm long and about 1.5mm in diameter (total width across the threads)



These are at f 5.6, so diffraction is starting to hurt the resolution. Smaller aperture would help depth of field, but at a trade-off against diffraction.

Of course, you should use a tripod for this. Attaching one to a Q can be a bit tricky though - my tripod plate is too big for the bottom of the Q when the K adapter is attached - the adapter and the plate want the same space. Fortunately, the adapter can be fitted with the same tripod foot that the DA* 300mm F4 uses. Even more fortunately, I have a DA* 300 from which to borrow the foot!

I shot some tiny things with SMC-Pentax M 50mm F4 Macro, genuine K-Q adapter and Q7.

Any cropping involved in those shots at all?
