Re: Sony 135mm f1.8 or new Sigma 100-400mm + Sony 85mm?

I own all three, but never use the 100-400 for portrait photography.

The real jewel is the GM 135 (on the RIV); however, you mentioned indoor portraits, for which 135mm might be a bit long... which leaves the 85mm.

If you are a pixel peeper (or crop a lot), I have found the Sigma 85mm ART to be noticeably sharper than the several copies of the GM 85mm I owned. The LenRentals MTF graphs verify this.

For convenience in street and travel photography, I use the Sony 85mm f1.8 (they can be had very cheaply on the used market).
