Pros: small, full of functions "set and forget" also present in the sisters nex ... with very comfortable electronic viewfinder ... although compared to the next a58 it was less contrasted and not led... present the electronic level very important for me that due to two serious interventions to the heart I always have dizziness since then and I make a mistake continuously tilting the photos to the right ..

Cons: the first distinguishes all slt and nex under the a99 .. i.e. the castrated firmware .. many functions blocked from one model to another... the second serious flaw is noise .. indeed the noise reduction unfortunately present ( unfortunately ) even on the raw that can not be turned off .. and tends to make photos above iso 400 of watercolors.. from 1600 iso files are unusable .. long ago I took a picture at sunset and having the automatic iso the sony even with good light tend to raise the iso to 1000 and up .. well.. there was a giant crucifix on a hill in my country.. it was gone haahha.. pretty much the nr had mistaken it for a noise artifact . .boh .. literally disappeared .. only the A700 had the NR settable to off.. after only trouble .. 3 frustrating flaw is the ability to focus .. ranging from decent with sunlight.. to the useless and frustrating already with particular contrasts or in low light .. guys you get to the point that at sunset does not focus on the trees with the sun behind .. or in church begins to go back and forth until you give up and blur everything ..

Opinion: apart from the pros and cons listed, I must say that with the possibility of removing the noise nr would have been an excellent travel companion .. as well as the a77 with the same strengths and weaknesses. I paid her 90 euros new for a defect in the flash .. for me useless ... I would have liked to have the nikon cleaning with the same sensor but with its same functions as the slt and nex menus .. because with an 18-200 I covered everything .. I still use it .. as long as his lens lasts ... Another peculiarity is in the sensor .. despite having the same resolution as sister A55 .. I don't think it was the same sensor.. the a55 and the C3 nex had broadly the sensor of the d7000 and I noticed having had them both .. from the a37 onwards they changed something I think because of the overheating of the sensor itself .. in any case at high iso I noticed obvious differences .. With the 18-55 standard weighs a nothing ... it is one of the few that with the electronic shutter on the first curtain manages to make a decent night photo on the mini stand of the manfrotto without the slightest choppy .. ( the d5300 with the 18-55 afp for example fails and moves everything because of the standard shutter ) .. another peculiarity the ring has preset the program for quick shots (12 ) but unlike the sister a77 that I also own .. they are only at 8 megapixels in jpeg fine .. but I assure you that for photos on the fly to seize the moment is a must.. another note of merit on this and on the slt in general until the a77 mk2 was the stabilizer based on the sensor in motion .. if you suffer from dizziness like me avoid the stabilized sensor that does not intervene when you press the shutter button in half .. because with a tele from 200 mm onwards will vomit .. guaranteed.. the a77 mk2 and the a68 had partly solved although at the expense of some overheating ..
