Ok we all know how lovely, fun and addictive legacy glass is.
Now, let's say I want a reasonably size fast zoom for my NEX... There's none. Ok, so what if I want to adapt say, a Tamron or Sigma 17-50/2.8 (or close anyway), how do I do that ? What about aperture selection on modern lenses with no aperture ring ?? What about EF or Nikon F or G, or Minolta lenses or Pentax current lenses ? I know there are two adapters for the Minolta/Sony lenses but what about the other mounts ? I have a cute fastish Sigma zoom in EF mount which AF is broken, but I'd still like to try if on my NEX, how do I go about it ???

You need this to get the electronics of the lens talking to the electronics of the camera. My brother has a 70-200/4 EF lens that I'd really like to try but even I balk at the cost of this adapter (sigh)

There are dumb adapters (no electronics) for lenses that have no aperture ring. I use one with my Pentax DA10-17 fisheye. The issue is that you have limited control of the aperture. There is a slide switch on the adapter that allows 5 different settings from wide open to fully stopped down.

Not such a big deal on the fisheye, I shoot it at f/8 most of the time anyway, but you aren't going to have full aperture control. My Tamron 28-75/2.8 on the other hand has an aperture ring so it's no issue.

Whether or not 5 aperture settings make the lens worth using is up to you. If it isn't you either spend the money for a smart adapter or you do without.

ymmv ;)

Buy the lens in nikon mount, get an adapter (fotodiox has a decent one) that has a ring to let you control the aperture by pushing the lever. You'll have to guess at the aperture size but not a big deal.

I think the price is very high, not bet going with this adapter, I prefer to go with the 55-210mm E-mount for about 350 bucks, or the 18-200 , but its price is about a little over 800 buck, (Tamron is a little cheap ) is very small compared with some lenses of this type, of very good quality for video too and the AF is faster than the 55-210mm.

If you want a Sigma 17-50, then why not just get an a57 + an alpha mount lens? What's the point of giant lenses on tiny bodies to get a normal range zoom???

There is a picture and short review of the Tamron 17-50 f2.8 zoom on a Sony Nex (with manual adapter) here:
Darin McQuoid Photography

Does not mention what adapter it is or how balanced/unbalanced the camera /lens combo is, but it does say:
"Handling: 3/10 - Terrible due to the focusing ring. Will be much improved when/if they make a native E Mount version."
