I am not excited. It's a long list but most items don't really do much for me - or most other 7D users.
Don't presume you are the supreme exemplar of all 7D users. Personally, as a 7D user, I find many of the new features to be very welcome. They are free, and they give new live to a my camera, rather than requiring that I buy a new 7D II THIS YEAR...something I don't have the funds to do. I believe the majority of 7D users are more like myself than you...welcoming FREE IMPROVEMENTS. The vocality here is a minority.
* Buffer size ... fine. Hardly ever take more than 5-10 shots in fast series anyway. I know, for sports shooters it is different. But I bet, 95%+ of all 7D users are not going to use 23 (25) RAW buffer more often than I do.
A deeper buffer is always a good thing. Its not about the number of continuous unbroken shots...its about how many full-framerate shots you can keep taking, even if they are in short bursts like 3-5 or 7-10 frames, before the camera has to start slowing down. Right now, with my bird photography, even though I usually only take 2-4 shot bursts for perching, wading, or standing birds and up to around 8-10 for BIF, its NOT infrequent that I find the opportunity to take multiple bursts one after the other, before the buffer is empty. A deeper buffer is VERY WELCOME...especially when paired with a higher speed CF card. I already get around 24-25 shots...this firmware update adds 7 more...which would mean I can get around 31-32 now. ABSOLUTELY NOT COMPLAINING ABOUT THAT!!
* Auto-ISO ... upper ISO limit. Good. But still miles away from fully functioning Auto-ISO (as seen in the Nikon D800, D4). This impementation is still a lot inferior to Nikon's D7000
This is also a welcome feature. There are times when I would prefer to shoot at ISO 6400 and expose properly despite the noise, than shoot at ISO 3200 and have to boost in post. Noise is bad either way, however an extra stop is an extra stop, and from a shutter speed standpoint a single stop can be the difference between getting the shot and not. Again, most definitely welcome feature.
As for Nikon's functionality, the only thing the 7D is lacking vs. the D7000 is the minimum shutter speed option. The minimum shutter speed exists in Canon's direct competition to the D800 and D4, the 5D III and 1D X. There are some additional options on those cameras as they have corresponding camera HARDWARE to support them, such. This is just a firmware (software) update to an old camera, its not adding new hardware, so we can't expect additional Auto ISO features that require hardware counterparts. Competitively, Canon is pretty level here, and at least they are offering this enhancement to an existing and increasingly old camera body...FOR FREE.
* faster scrolling in zoomed playback ... fine. No big deal. Why not from the very start?
When your out in the field and you need to chimp quickly, better firmware performance is always a bonus. I like my birds eyes to be sharp, but good shots are always happening around you when birds are flitting about. Spending a lot of time zooming and panning to determine if a shot is a keeper or not is also a valuable thing. Better yet if performance is improved for those short video clips that are necessary to really capture what your subject is doing when a still doesn't do it justice.
Stop complaining. If you want what Nikon has to offer, ditch Canon and move to Nikon. Bitching and moaning about Canon when they DO GIVE YOU FREE S___ ain't going to make them your friend. It won't change the past either. Going forward Canon offers competitive features like in-camera retouching and better bracketing, as well as things like in-camera multiexposure or even things Nikon cameras can't always do...such as continuous shooting at a lower rate once the buffer is full (this is an area where Canon excels, but one where Nikon is hit and miss, miss more often than not). So if you stick with the brand, you won't be disappointed. But I don't think thats going to satisfy you...the only thing that will really satisfy you, based on your comments, is a Nikon camera. SO GO GET ONE ALREADY!
