Finally got a Tamron 90mm f2.8. I have only use it manual focus but the variant I have is effectively manual focus so... Camera can produce some really nice photos with it too
.
The main problem I'm having is finding good glass from companies other than Sony to fit the E mount. I can use a converter for A mount lenses. The are often advertised for the Sony/Minolta A mount and may have a screw head for a body mounted focus motor. The Sony adapter for this is over £200.
I had a choice for the above Tamron 90mm: buy the cheaper adaptor without the motor and go for a £350 lens, cost £450: buy the lens I got with the more expensive adapter, again about £450. Either of these would have provided at least some form of autofocus. Or buy the cheaper version of the lens and cheaper adapter - cost about £300.
I can use lenses designed to fit Canon and other mounts via adapters but the camera often takes two or three seconds to focus and in many cases won't provide autofocus at all. That means higher speed photography is difficult or impossible, forget sports unless you can use manual focus old style.
In even moderate weather the back LCD can be almost impossible to use, This may be an issue with me rather than the camera - gotta read manual sometime. The eyepiece is fine even in bright conditions. You are not going to risk eye injury photographing into sun, unlike a DSLR.
Overall I am very positive about this camera, but, unless they manage to get more 3rd party glass available for the E mount then I can't recommend it. The camera is actually good but the range of lenses is limited.
