No, I am a reviewer. The CZJ series of zoom lenses made with Minolta, Canon FD, Olympus OM, Nikon F, M42, Exakta and Praktica bayonet mounts were made under contract by Sigma and Cosina. They are not optimised in any way for digital use, and the rear element is not coated to prevent ghosting when used with a digital sensor. In fact, they are not really up to CZJ quality standards at all.

After reading all the responses you've gotten I don't know if my experience will help all that much but here goes: I got the NEX-5n a few months ago for such a good deal that I got the Sony E-mount 55-210 lens also, instead of getting an adapter to use my Canon lenses. My reasoning was simply that I needed to get away from the size and weight of the Canon FD and EF mount lenses and go to something lighter, more portable, more gentle for my old body (!). I've been more than happy with my choices!

You get cheap adapters on eBay for most modern cameras that allow different lenses..
A zoom lens that claims macro capability is not as good as a real macro non-zoom (I tried various).
I had good results photographing flowers using a Nikon macro lens, a Tamron macro lens and a Tamron 200mm (not macro) on adapters to suit a Panasonic micro 4/3 outfit. The 200mm took photos from 9 feet away and the macros worked a whole lot closer with entirely different perspective and less in focus. A tripod and delayed action release are vital.

This IP camera connects to my home wireless network. It is a stand alone device on the network (once setup) and has its own IP address. It (evidently) has its own web server.

The camera does need to be plugged into household electricity. I had outdoor wiring in the general area of the feeder, so just extended it to the camera. The wiring is all underground and then goes up to the feeder inside the pole, so it is never exposed to the elements and critters.

There are lots of different cameras available and you can probably find something that fits your situation.

This is more for the bird folks here rather than the photo folks, but it does involve cameras, so.....

I needed to replace a bird feeder this past fall, so I decided to build a big hopper style feeder that could hold a couple weeks worth of sunflower seeds. When designing it, I included a small "room" that would hold a web/IP camera. The camera can tilt and rotate (but not zoom), so it is set up to look one way to see birds getting sunflower seeds or turn to look out a window and see a peanut feeder. People looking at the feeder over the internet can use controls to position the camera.

I made design errors (of course), the camera resolution sucks and it really needs a zoom, but it is still fun to get a closer look at the birds on our feeder. And I don't have to get off the couch to look out the window when I want to see birds. :lol:

This feeder is in St. Louis, so we see Eurasian Tree Sparrows. Otherwise, its just typical US midwest birds. The camera runs off my home network, so I haven't opened it to public access, but would provide a login to a few people for a short time if anyone is interested.
