Sony  Alpha Mount Lens Adapter

I wanted to work with mirrorless imaging while preserving my options to add SLT later. If I had bought E-mount lenses, I would have been 'stuck' with mirrorless focusing. I found that mirrorless is good unless it is an action video/photo OR you doing video-zooming. I did eventually get the LA-EA2, but still like the EA1 when there is very little 'action' or zooming. I did have to forsake the in-lens-stabilization in SOME of the E-mount lenses, though.

I keep reading about people experiencing no autofocus capability. Update your NEX firmware to version 3. Update your adapter to version 2 and it will work with: SAM Lenses * DT 18-55mm F3.5-5.6 SAM (SAL1855) * DT 28-75mm F2.8 SAM (SAL2875) * DT 55-200mm F4-5.6 SAM (SAL55200-2) * DT 30mm F2.8 Macro SAM (SAL30M28) * DT 35mm F1.8 SAM (SAL35F18) * DT 50mm F1.8 SAM (SAL50F18) * 85mm F2.8 SAM (SAL85F28) SSM Lenses * Vario-Sonnar T* 16-35mm F2.8 ZA SSM (SAL1635Z) * Vario-Sonnar T* 24-70mm F2.8 ZA SSM (SAL2470Z) * Distagon T* 24mm F2 ZA SSM (SAL24F20G) * 70-200mm F2.8 G (SAL70200G) * 70-300mm F4.5-5.6 G SSM (SAL70300G) * 70-400mm F4-5.6 G SSM (SAL70400G) * 300mm F2.8 G (SAL300F28G) Also, yes it's slow compared to the kit lens, may take up to 5 seconds, never 10 seconds, but you will be using it with lenses that do not have image stabilization nor do you have the continuous auto-focus option. So you're not probably shooting fast moving object, thus it's not exactly a major con. P.S. not sure why the IQ drops so significantly when the uploaded image gets resized by the Sony website.

You need to update the software for the camera. update via USB through sony support.

I bought it used. Tried it on my NEX-3 and "Surprise!". AF works like a charm on my 10-20mm F3.5 EX DC HSM Sigma wide angle zoom. Still too expensive IMHO. That is a definite bonus as I was prepared to use it for manual focus...

Both the AF and Aperture controls work well and quickly, and the A-Mount SAM lenses are cheaper (and more plentiful). However, the A-Mount SAM lenses don't feature image stabilization (since it's included inside the bodies of regular Alpha SLRs) and the are much louder (really only important if you plan on shooting movies). Will work with all A-mount lenses, even the old Minoltas, but the AF will not function. These shortcomings are NOT the fault with the adapter. Do yourself a favor and invest this adapter and start growing your SAM lens collection...

While I was fairly disappointed in the manual focus only limitation. I was glad to finally be able to implement my sony alpha lenses for my NEX. The great news is that at the 2010 Photokina, Sony announced auto focus compatibility for alpha lenses attached to this adapter.

This adapter is not much better than an all mechanical adapter with an aperture ring built in to the adapter - which you can get to mount other brand lenses on the NEX for much less money. Theres barely any advantage to adapting Sony A-mount lenses over any other brand for which you can get 3rd party adapters. I will say that manual focusing on the NEX is really very easy, even in bright sunlight with the LCD screen. I would love to give this adapter 5 stars, but the lack of autofocus is a major oversight.

I just got this today and nowhere on the product website description does it make note that this will not support autofocus. Added to the outside of the box it has a sticker added that it is "For MF (Manual Focus) mode". Inside in the instructions it says AF is not available with the adapter. It also says in the instructions (for the first time - anywhere) that it does not support teleconverters. I mistakenly presumed that when coupled with one of Sony's "compatible" lenses that they would work harmoniously. Not until I recieve the product did I find these material limitations. Mechanically the adpter looks fine - but my expectations were set much higher from the product description and the word "compatible".
