Sony a9: The Sony a9 is Not ISO Invariant and MC-11 Canon Glass Performance

Jason Lanier released the first video demonstrating how well the Sony a9 works with the Sigma MC-11 with Canon glass and it shouldn’t disappoint anyone that plans to rely on it initially. The demonstrated performance in the above video is very impressive for adapted glass or even native glass under the shooting conditions.

Below Greg Thurtle gets gives his first thoughts on the Sony a9 and they are very muted. I shared this video because he talks a little about how the Sony a9 uses FTP to share files and I haven’t seen anyone else talk about this feature yet.

Then there is the recent article by DPReview “Sony a9: more speed, less dynamic range“, which is DPReviews second controversy piece on a groundbreaking camera this year; The first was about the Fujifilm GFX. It is my opinion that DPReview improperly titled this article because the simple true is that the sensor is simply not ISO invariant and while this fact does dimish your ability to artificially add dynamic range, it does not limit standard dynamic range one bit. The majority of users that this camera is designed for won’t miss the ability to push and pull to the extreme, but DPReview is going to get a lot of traffic from this non-issue.
