Anyone has problems installing Lens Firmware update for the 55-210? My NEX 6 can't be detected during update even when I followed all the instructions. The update program hang. Windows 7 SP1.

TTL yes, HSS also yes! LED video light is surprisingly bright!

But it can't be used as a slave on Nex 6 unless u have another HVL mounted to use as a trigger

I managed to get plenty of keepers with my 55-210 at SAE. DMF is too slow, so turn on face detection and 10 fps and shoot. Half a sec to focus and then fire away! Models were brightly lit on the runway and I can nail the focus even at 210mm. 3 conditions need to be met to turn on face detect and I'm pleased with the results. Phase detect focus is much improved with the new lens firmware! I got better results than my sel35 on first day with DMF on.

Sony Style is giving 20% off on Nex 6. 0% instalments. Good deal!

Sigma 19>SEL20>SEL16

But SEL20 turns your Nex into a stealth cam. Great for street!

Yes, you can use both. SEL35 cannot but SEL30M can as well.
