The lens is very well calculated for a macro for Sony, the Tamron 90mm macro that I had at the Canon before, was less comfortable (unbearably slow during AF, the imaging performance was weaker). One should be careful with the manual turning the focusing ring in AF mode, which gets not according to instruction of the lens! In low light, the AF gets out, then you have to set it manually. Color reproduction is superb, enjoyable weight easily with good workmanship and to Made in Japan. Since the objective is to see the reviews of the photography magazines hardly likely to be a secret because of the moderate price. Can I recommend all round.
