NEX and a Zeiss Jena Flektogon

One of the features of mirror-less cameras is the small distance between the lens mount flange and the sensor. That small flange to sensor distance opens up the possibility to use adaptors to mount older manual lens on the camera. If you can afford them, you can mount Leica M-mount lenses on a NEX, these lenses have the advantage of being designed for a mirror-less film camera which itself had a short mount to film distance. I don't have that kind of money to spend at the moment!

Why no depth of field preview button?

When I first received my NEX-6 I thought that one of the things I was going to have to live without was depth of field preview. On a DSLR DOF preview is accessed by a button which causes the lens to stop down. After experimenting with manual focus I realised that on the NEX the lens is normally stopped down which means that the camera is normally showing DOF preview. Even better, because of the electronic view finder the image is always bright.

The NEX-6 Shutter

The first thing I noticed about my NEX-6 was the fast speed of response of the shutter, the delay is very short indeed, After dong a bit of research I found that the shutter is 'opened' electronically and closed mechanically. The 'Front curtain shutter' entry in the settings menu controls this behaviour.

I have sold my Canon DSLR

I faced a big decision, my EOS-400D was getting old and its poor performance above 100 ISO prevented me from making a lot of images. It had to go, but what to replace it with? I could buy another Canon DSLR, and to get the functionality I wanted but that would mean something like a Canon 7D. If I bought a 7D I would no longer be happy with the performance of my lenses, so that would mean major expense on the camera and the lenses.
