Wow, this is an excellent shot. How lucky were you? Photographically, it is also superb: it's extremely clear, and the colors are very good.
I've noticed that you have used the new 100 mm macro, which I just didn't get on with for macro. I have absolutely no idea why. It takes superb photographs, but my close-up shots were dreadful, so I stick to my 90 mm for my macros. Maybe I got a slightly dodgy model, although I think their quality control is probably well above excellent.
Thank you. I like the 100 mm macro and still have the 90 mm too. I'm slowly adapting to this macro stuff and the biggest mistake I make and still do, is trying to get too close, thus narrowing the D.o.F.
It's an on-going mental approach thing, which I mostly counter but the urge to get right in there is strong. I took a few nice shots of this spider, the colours make a major difference.
I have also used the 1.4 Sony teleconverter, which seems to work well but it's an occasional use item.
I'll add a few more items later, thank you again.
