has a microphone input. Sony A7C. Sony Alpha 7R II. A microphone port allows connecting external high-end or specialized microphones. has a socket for a 3.5 mm audio jack. Sony A7C. Sony Alpha 7R II. With a standard mini jack socket, you can use the device with most headphones. has a stereo microphone. Sony A7 III, A7R III, A9 Astro Settings: Self-Timer or Remote. To avoid any micro movements on the camera when pressing the shutter release button, make sure to set the Self Timer mode to 2s or preferably 5s. You can do this by pressing the left button on the rear control wheel. Alternatively, you can use a remote. Since the a7iii at least gives 1 stop better performance for AF, I know I won't need to worry and it should work like the a9 or a7riii. So for me, even just that difference pushes the a7iii into a whole different category vs the a7ii. However, this is only worth considering if you anticipate using $3000+ lenses + teleconverters etc. The Sony a7III supports a maximum continuous drive speed of 10 frames per second in Hi+ drive mode with both the mechanical and the electronic shutter. But this speed is only achievable when shooting compressed RAW or JPEG. The a6700 supports a maximum frame rate of 11 fps when shooting in Hi+ drive mode. With a standard mini jack socket, you can use the device with most headphones. has a stereo microphone. Nikon Z6. Sony A7 II.

Here is a quick specs and size comparison for the Sony a7SII, Sony a7S and Sony a7RII. You can take a look at the key differences between the three Sony full frame E-mount mirrorless cameras. Sony a7SII ($2,999): Revolving around a full-frame 12.2MP Exmor CMOS sensor, the a7SII is capable of internal UHD 4K recording. If you get an A7ii, you'll want Sony FE (full-frame) lenses for it and a lot of them have four-figure pricetags. There are only four sub-$500 lenses only one of which is a zoom lens. The E (crop) lenses won't cover the entire sensor and you'll either have to crop or get vignetting. Full frame glass tends to mean you need a $2k-$3k budget for a7ii does NOT have continuous eye tracking focus, it can only find eye using af-s (DMF afs type..). a7iii or a9/a7r3 is what you should have bought. also a7r2 can do eye af-c , but not as reliable/fast as third generation bodies. ah sorry, typo. i meant to say I know it only works on AF-S.
