I wouldn't mind seeing non OIS lenses in the future, now, but they are pushing the industry and leaving many in the dust to play catch up. I was quite impressed with the 1080P output of the camera, and the 50Mbps XAVC S codec makes for a reasonable sized file that will survive all the way to broadcast, if necessary. is more about “I can more easily justify this purchase” than it is about actually going around using mount-adapted lenses all the time. if you *want* a narrow aperture and the camera doesn't feel it has enough light it will open up the aperture further.
I can see how a CDAF FF camera with such shallow DOF capability has enough difficulty to work with that the live view display settings are less than optimal (but perhaps CDAF on a FF sensor is already less than optimal). If you own a Leica m240 and can stand to use a camera body that’s relatively uninspired, go for the a7s.The negatives of the A7s are low priorities to me so I readily trade them out including lower resolution and slightly lower dynamic range at ISO 100. When I first purchased the a7s’s older brother the a7r months ago I had no idea what I would use it for… other than a cheaper alternative for my Leica lenses. Given the larger than average size of 7S pixels and its relatively new technology, it is logical to assume that the 7S Baseline ISO has to be higher than the average ISO100 sensor which features smaller pixels.
That’s because if you all remember from my Sony a7R II review I mentioned I wasn’t a fan of the larger bodied cameras and favor the 1st generation ones, so that’s why I got the 7S for this wedding. Our wedge shots verify the camera has less dynamic range at ISO 3200 than at ISO 100, which is absolutely expected, as base ISO maps a full pixel well to white in the digital Raw file. While the a7S is a capable still shooter, Sony has emphasized that its real focus (no pun intended) is videography.Also, you say 'if the camera doesn't feel it has enough light it will open up the aperture further' - that's exactly where the problem lies, b/c the camera's algorithm for determining if it 'feels it has enough light' needs to be more conservative. The camera is full of professional-level functionality whilst also being completely usable for the experienced freelance video content creator. It certainly serves a unique purpose and does so well (actually two purposes: excellent low light work, plus strong video capability).
In other words, the ISO that has the highest conversion gain, expressed as electrons per digital number). In low light, the area over which light is collected becomes important (more is better), and the A7s has a lot of additional area compared to the other two cameras. I thought you were interested in the aperture staying wide open, but you're more interested in a usable preview even when your exposure is set such that sans flash, you'd get a dark exposure. For as still photographer it is really hard to justify to shell out this kind of money on a very limited still camera with limited lens selection. There is nothing wrong with a camera that is a specialist, whether it is high-end, high megapixel stills camera like Phase One or Hasselblad medium formats, or a video-oriented cameras like the Sony a7S and the Panasonic GH4.The bigger question is: where are folks getting the notion that ISO 100 to ISO 1600 are 'extended' settings on the a7S? And I love AF, MF is tedious, focus-peaking is rubbish and lens adapters work but make AF so slow it is ridiculous. To get at the other question you're asking - pushes of other ISOs, our ISO-invariance test is actually a good proxy as it shows you the ISO beyond which there's no more benefit to performing the gain by increasing ISO in-camera. I fail to see how looking at the comparison of ISO 6400 as the target ISO is very useful given that noise is always more likely there in low light.

Canon has subsequently upped its game with the EOS 5D Mark III and the lessons it's learning from the development of its Cinema EOS line, but in general video is promoted much better than it's supported. I tend to believe the proper ISO Baseline for the 7S is 400 which makes sense given its larger pixels.Film industry accessory manufacturer Cinoflex was recently tasked with rigging up a new Sony a7S mirrorless camera for use on a Chevrolet commercial. We think we've worked out how you'd conclude that ISO 3200 is the native ISO (though we don't believe this to be the case). It’s tricky because color is such a subjective thing, but after a few days shooting with it I can say that the tones have a softer feel to them.
Great Deal
