Hi everyone !
Photozone juste released their review of the FE90, and it is quite impressive. You can check the review on this link : http://www.photozone.de/sonyalphaff/974-sony90f28macro
And here is another review I've found of the 85f1.4 G Master : http://eh-photo.de/blog/80 Quite interestingly, the reviewer finds it to be sharper than the FE90, which is again highly impressive
With the FE55 and these lenses, Sony really has some legendary lenses in its line-up
