Hi. I'll probably pick up a new camera next year, and am weighing up the pros and cons of APS-C vs FF. I'm curious - why is there so much interest in the 5Diii compared with a 7Dii? A 5Diii with 7D build, AF and speed would seem to be many people's dream come true. I appreciate many of the benefits of FF - shallower depth of field, less noise at higher ISOs etc. But with all of the hype, you start to think that the only benefit of the APS-C sensor is the lower price and 1.6x crop for longer lenses, but for everything else it is an inferior product. If a 5Diii was virtually identical to a 7Dii except it had more megapixels on a larger sensor, would the joys and benefits of using a FF camera really be that noticeable in the real world? Do people who have made the switch from APS-C to FF agree that it is the best decision that they've ever made and wish they had done it sooner? Or after making the change, have you been left wondering what all the fuss is about? Would appreciate your thoughts. Thanks.
Lots of people have their own preferences and reasoning around this. The problem seems to be that from the numbers I've looked into I would think that the 7D didn't sell very well. So there may not be a 7DII in that sense.
And I personally can understand why that is since I came to the same conclusion. The price difference when buying a complete new system is not that big and at that point I figured that I'm much better off with the full frame 5DII since that is what I really wanted to begin with. The 7D in a way is really a specialty camera for wild for instance. There the (supposedly) faster AF and the crop makes sense to some degree while maintaining high enough build quality. For everything else a 5DII type camera is just a bit better. And the folks that are on a budget or not that into the technical details a good Rebel kit is a really good choice.
Just look at the usage data on flickr for instance. It's mostly Rebels, the 5DII and a bunch of older models. The 7D and especially the 60D don't fare very well by that measure.
