What brand of adapter is everyone running for the NEX mount? Anyone using the Phottix? Considering picking up an A7r to play with my 31mm LTD and I don't see anyone talking much about the quality of the lens adapters. Is the Voigt worth the money? Fotodiox?

Beautiful Rose-Crowned Fruit-Dove Christine, and lots of nice detail and colour.

Was that in Canberra?

Thanks

That was actually taken at Taronga Zoo, using the A100 macro.

Here is a picture taken at the National Botanic Gardens at Canberra. This brazen little thing wasn't a bit afraid of me

The adapters vary in quality.
I use fotodiox in the beginning. They made good adapters, but some what more expensive than ebay sellers.
For the expensive lenses, I use the 'more quality' adapters, but I also have to return a few expensive adapters (100usd-200usd) due to quality failure.

When buying from ebay, you can look for:
- Seller's feed back. I always buy from known sellers.
- Number of sold item of that adapter. The best adapter sold a lot.
- Look for the number of screws on the adapter. Usually 3 screws for cheap adapters, upto 7 screws for the more durable.
- Look for the bayonet springs. They help to fit the lens more sturdy.
- Cheapest is not always the best choice.

Would you trust an adapter with 3 tiny screws to hold your 2-3000usd lenses?

I always double check the screws, the bayonet flags/springs, before I use them,
just unscrew and check. 3 screws might be ok if they are a bit larger in size and longer/screwed in deeper.

Hope that helps

I spent 3 hours with an A7 yesterday. I don't think I will be picking one up. Too small for me to use for an extended period. My hand started to cramp up after about an hour.

Some trivia for you. It only takes 3 threads worth of engagement to develop the full tensile strength of the fastener.

We always allowed four threads minimum due to thread lead-in (relief) variations, and more if threaded into low-strength materials like aluminum - where the soft threads would pull-out before the screw would break. However, with cheap adapters it is more the combined strength of the 3 small screws. Pentax used 6 larger screws on the body flange even on the MX.

Designing without using a safety factor is daft anyway.
