Sigma 150 f2.8 Af Apo Macro EX DG HSM
I tried this lens at a photoshow, and was positvely impressed by the overall equilbrium between size, working distance and ease of use, thus I ordered one at my local dealer.
Here are my first impressions after a couple of days of use: it is a nice stubby lens with reasonably fast and very quiet Af , very good sharpness and surprisingly good colour rendition. The unusual focal length (other long macro are 180-200mm) is compensated by the crop factor of the D70 Aps sensor, so that it result to be a very handy lens to use. From my first tests it seems that this lens works well both for studio and for outdoor macros, so that I traded my 105 sigma EX.
Here are some studio and nature shots:
the fish is 4.2cm long
A 100% crop of the original picture untouched (above) and with a little USM (below),
A=64 R=1.8 T=0
the colour rendition is pleasant
Taken at f 22
A collaborative wasp
A 100% crop of the original image.
Did I find any problem? maybe...
watch out for flare...(deliberately taken nearly counterlight and without the lens hood)
In conclusion, l like this lens a lot, and I think I will like it even more once learnt better how to use it .
