What the Sony SLT A57 may have the other described well in front of me. I will hereby assign my points because I've never had a digital SLR, my last was Minolta Dynax 600i, since I tested a whole series compact cameras, with much disappointment. The more technology, the less useful they were. I just had enough and found the SLT A57, bought the Tamron 18-270 with equal thereto. Fortunately, because the Sony SAL 1855 is a toy for beginners. So I'm doing now at last photos, which can be seen - even in low light conditions (here is a lot on the lens and not the camera!) In my living room almost dark in the middle of the night. I do believe that it could still be better, then I would certainly get 2 thousand out of his pocket. So I have my real fun for only 1200. Conclusion: Those who speak ill of the Sony SLT A57, does something wrong or has unrealizable desires. I would nevertheless a: a better battery (when traveling, I can not invite every day, after all, I want to spend their holidays), or makes the Pentax, battery / battery in alternating operation, depending on the option. Strong buy recommendation from me with 5 stars.
