I get asked from time-to-time to comment on different cameras. It's not a favorite topic of mine, but these posts are usually popular. People want new cameras and they're searching the web to find any information or advice on what camera to buy.
Most recently I was asked to compare two Sony cameras: the SLT A77 II DSLR (well, sort of a DSLR, anyway) and the A6000 compact interchangeable-lens. Which is better? Which should you buy?
There are some similarities and some differences between the two cameras. The two cameras share the same 24 megapixel APS-C sized sensor, but they look completely different. They have different auto-focus systems, but one is not necessarily better than the other (they're just different).
Image quality is identical between the two cameras. Inside, the two cameras are much more alike than not alike. One cmaera will not give better quality results over the other. They are the same. Both are excellent.
The A6000 is much smaller and weighs less than the A77 II. The A77 II has a slightly better and more versatile back screen. The A77 II is weather sealed while the A6000 is not, and the A77 II has image stabilization while the A6000 does not. Depending on the type of photography you do, those differences could be significant or they could be meaningless.
One area where the two cameras are not similar is price. The A6000 has an MSRP of $650 (body only) while the A77 II has an MSRP of $1,200 (body only). I personally don't think the A77 II is twice as good as the A6000, unless you plan to take it out in the rain.
