@ Mawz - In my book, the combo NEX+SB isn't the best platform for bulky f/1.4 glass ( and quite expensive too ). We don't agree, sorry. Also, a 35/2 lens +SB = 25/1.4. Which other options do you see with a 'empty' adapter on the NEX, apart from a Summilux 24 ? I don't care for APS-C lenses like the Zeiss ZA 24/1.8. In the eventuality of a FF mirrorless in the future it wouldn't be of any use. Of course, in that case, the SB will be redundant too.
What about some M42 : Flektogons, Takumars, etc, - Any supporters of the old screw mount ?
Note there are compact f1.4 lenses, the Nikkor 35/1.4 AI-S comes to mind, in fact most of the MF f1.4's are reasonably compact (with the exception of the new ZF/ZE 35/1.4 and the Samyangs). The advantages of the Speedbooster for me are to preserve the DoF effects of fast lenses or to provide focal length/DoF options lacking natively or via regular adapters.
A 35/2 may well be a 25/1.4 on a Speedbooster, but you won't see a 35/2 that can match the ZA 24/1.8 in optical performance for the same budget (counting the speedbooster cost) without being significantly larger (ie the ZF/ZE/ZK/ZS). That said, if you really want to avoid APS-C lenses there are some decent options. The Flektogon 35/2.4 has a well-deserved reputation for excellence. The OM 35/2 is mediocre, their 35/2.8 is much better. Nikon's 35/2 is good but its reputation exceeds its performance (a good lens, but not a great one), the Series E 35/2.5 is every bit as good aside from flare performance in my experience, and much smaller & cheaper. The SMC Takumar 35/2 isn't bad, but performs much like the equivalent Nikkor.
At 85 my choice is the Nikkor 85/1.8 K (the one which is usually mis-identified as an AI lens, which it is not, although some came factory-converted to the AI aperture ring but lack the AI mount), otherwise the 85/2 AI-S is good (but like the 35/2, not excellent). And the Tamron 90/2.5 is an excellent option here, I use one regularly as a 135 equivalent.
