I recently purchased a Sony SLT-A35 and I've been very pleased with it thus far. I only the supplied kit lens and I'm interested in purchasing a telephoto zoom lens for it. Right now I'm looking at the tamron 75-300 mm lens due to the low price and the good reviews. There's also the Sony version of the tamron which is more expensive. Finally there is also the Minolta "beercan" lens that can be purchased used at a reasonable price although I believe that one is a 70-210 mm lens. Which of those is the best option? Feel free to offer more suggestions but keep in mind that I can't really afford anything more than the Sony which is $250.


Answer
Unless you absolutely positively need the extra "reach" of 300mm (the Tamron 75-300mm) I strongly suggest the Minolta Maxxum AF 70-210mm f4 simply because its a constant aperture zoom. Also, I own and use the older manual focus 70-210mm f4 "Beercan" and the optics of the AF version are identical to mine. Its one sharp lens.

New Camera Advice Needed?

I currently have a Sony DSLR A200 and I'm looking to upgrade. I want something with even more clarity, possibly more features, quicker speed, and ability to switch from manual to auto (I know all cameras do this but not all have full capabilities in both modes). Any advice? Ideas? Etc?


Answer
Since you didn't bother to tell us what lens or lenses you have with your A200 I'll just guess that all you have is the 18-70mm zoom that came with the camera. From reviews I've read it isn't the best lens in the Sony lineup - which is probably why it was discontinued. If I'm wrong and you have several lenses then there is no doubt you'd best stay with Sony unless you want to buy all new lenses.

The A200 is a fairly old model (by DSLR standards) so wanting to upgrade is probably a good idea. I suggest looking at the two newest from Sony - the SLT A65 and SLT A77. These are next generation DSLRs using Sony's Translucent Mirror Technology (TMT) first introduced in the SLT A33/A35 and A55.

These Sony SLT cameras are the only cameras currently on the market that allow you to have full-time continuous auto focus whether you're shooting still images or 1080 HD video. Another plus for TMT is that you can actually see the scene even as the exposure is being made. The viewfinder never goes dark. TMT also gives you the fastest shooting rate - 12fps (frames per second) with the SLT A77.

Although some models from Canon and Nikon allow for auto focus when shooting video its the slower, choppy contrast-detect method whereas the Sony cameras use the faster and smoother phase-detect auto focus.

Any lenses you currently have for your A200 are fully compatible with the SLT DSLR cameras.

In the future the movable mirror found in today's DSLRs may be an obsolete technology. Look at the success of the mirror-less cameras from Sony (NEX-3, NEX-5) and the models from Olympus and Panasonic. Nikon has announced plans for a mirror-less camera and Canon probably won't be far behind. My knock on the Sony NEX cameras is their new "E" lens mount. Lenses for them are few and pricey.

So read what's being said about the SLT A65 and A77.
