All captured with K20D plus one of the following lenses: Pentax-D FA 100mm F2.8 macro, Sigma 17-70mm F2.8-4.5 DC or Sigma 100-300mm F4 EX DG APO HSM. Just for fun (i.e., no prizes), can you match the lens to the shot without looking at the EXIF data?

Thats a difficult task without knowing the amount of PP (if any) or the amount of cropping, But I'll hazard a guess at 1,2 & 4 been the Pentax.

EDIT: Sorry didnt realise you'd three lenses there, so 1, the 17-70 2&4 the Pentax and 4 the other sigma.

Good point, Alan.

All images were captured in RAW format and then developed in Lightroom 3.41 using the appropriate lens profile. Selective sharpening was applied using layers and the high pass-filter in PSE 9 after converting to 8-bit files. All 4 images have been quite heavily cropped, but I can't be more specific without giving the game away!

I'm not very good at guessing lenses, especially ones I don't have (which includes all of these) , but I really like the picture of the dung fly.

I have the Pentax, but I'm not familiar enough with the Sigmas to decide.

The dung fly is definitely the Pentax.

The moth definitely isn't (not sharp enough).

The bee probably isn't - overall it's a bit soft and therefore difficult to tell.

The hoverfly - not sure, could be the Pentax.

The dung fly is very good indeed.

...and the winner is...DrOrloff

The good doctor deduced correctly that 2 and 4 were shot using the D-FA 100mm macro. As for the rest, the bee was shot using the Sigma 100-300mm f4 EX DG and the cinnibar moth using the Sigma 17-70mm f2.8/4.5.

Contrary to what was stated in the OP, there is a prize: a mint Shepherd XE-99 flash meter. Shoud you wish to claim your prize, DrOrloff, PM me your address and it will be dispatched forthwith.

Many thanks to aliengrove and fatspider for participting

At least I got the Pentax ones right, the DFA Macro does produce some superbly sharp images.
