I am overwhelmed by the strengths and the weaknesses I can live. Other cameras have since perhaps your strengths - but with their infirmities, I may not live.
So - thickest PRO argument (in my view)
Full-frame sensor in such a compact camera? Hello? Where then are there any?
And - at the price?
== Topic - too little lens === selection
Is only partly true. While there is little lenses natively (FE-Mount) fit, but there is a huge amount of adapter
Selection to screw foreign or waste glass off. I have supported myself on the lenses of Voigtländer.
These lenses are built small and still bright. For example Nokton Classic 35mm F1.4. Large heavy
Lenses as I screw on Nikon's or Canon's turn would, at one A7 not look good.
With the VM adapter Voigtländer, I can even halve the close range.
BUT - now comes the BUT. Most adapter solutions do not support all the electronic features of the A7!
So autofocus ADE.
BUT - now comes the second one, however. I'm excited. It makes such a mistaken fun with the small lever itself
keen to ask - madness. That's like driving with clutch and circuit. The A7 supports finding the sharpness through a magnifying glass and edge detection (Fokuspeaking) very well. With Sony lenses, the A7 will automatically detect the rotating the focus ring, and switched to the magnifier. In a manual lens of course does not recognize it. I have put the magnifying glass on a Custum button. So that I can turn on the magnifying glass if needed, in 2 levels of magnification. Of course, not every image is sharp, but which autofocus makes every image is sharp? However, where there are no contrasts, no display. Then it becomes difficult to focus using the, but the AF does then also difficult.
== == Topic Battery
Yes it is not a double-battery charger. Yes you have to buy it separately. When Alpha 7AS but is an extra charger.
Conclusion? The A7 is calculated tough Sony. Who buys a A7R or even A7S, subsidized cross the A7.
Yes, the battery runs out quickly.
This has to do with weight. Clear the battery lasts a Nikon D610 longer, but the part is almost twice as heavy and has (surprise, surprise surprise, surprise) built almost twice as strong battery.
I have a second spare battery while waiting in his pocket and the camera does not consume space and weight.
== == Topic Lightning
Yes, the A7 has no flash. What lightning - but is a full frame camera - needs no flash!
(... It was not meant seriously now)
I got myself the Yongnuo it. The flash can be unleashed by radio. And costs a fraction of the astronomical prices
Sony, for your precious flashes. But even here a BUT. No electronic support from the A7 motorway!
So TTL or something you can abschminken. Since my focus eh makes manually more fun would this lens
and not send a signal to the flash. But what will support - is the choice of shutter curtain. So whether or not to be flashed on the 1st or 2nd curtain. This then can be realized other effects.
Summary - everyone has to define himself what strengths and weaknesses are. And that's the hardest.
