The 70D satisfaction poll had me thinking this would be a more interesting poll and, since someone there suggested it, this should expand on the happy vs unhappy binary with a little more variety of options.
I had a 7D, loved the AF, viewfinder, built-in level, and overall performance of it. However, i sometimes used this camera for landscape type shots because it was what I had with me when the scene presented itself and I was often disappointed with serious shadow banding if I tried doing much with the image in post.
I sold my 7D while it still got a good resale price and have been hoping a new 7D Mark II would arrive this summer with an improved sensor, hopefully providing cleaner low and high ISO performance. If the AF improved over the original, that's an added bonus. Once I got accustomed to the way it worked I was able to get adequate AF hits of birds, and even some bugs, in flight. Sometimes even in low light.
I had a couple 60Ds. I kept one of them because it's a nice light compact camera that makes a good walk-around or travel camera. If I were to buy a 70D it would have to be all that, possibly even back to the body design of the 20/30/40/50D, AND have greatly improved sensor performance. I'd not
buy it if it offered; more video features, WiFi, GPS, a bucket full of firmware features but no sensor improvement.
I have not yet chosen to replace my 7D with a competitor's camera, mostly because of one lens there's no good substitute for, the EF 100-400mm L IS. I could use a competitor's fast 70-200mm with a 2x adapter but that would likely cost me more than a new Canon body so I'm still undecided to pick a solution in this area. There may even be perfectly viable options in the micro/four-thirds range to do this job but I'm in no hurry.
So... Things to think about before voting, or buying.
• If a 70D shows up with a better sensor than the original 7D or 60D, and an improved AF system over the x0D line, maybe even comparable to the original 7D, it would have to be priced competitively with a used, original 7D to be worthwhile to some, depending on what their intentions are for such a camera.
• What level of sensor and AF performance improvements might you want from a 70D or a 7D Mark II to entice you to buy one?
• If the 70D doesn't have sensor performance improvements over the 18MP sensors that Canon has supplied over the past few years, will you still consider buying it if all it provides are some extra features like raw video out, WiFi or GPS?
• If the 7D Mark II gets an AF system comparable to the 5D Mark 3, maybe 10 fps, but does not get much, if any, improvement in sensor performance, will you still buy it?
• What is the minimum set of improvements, over the previous body being replaced, would you say is enough to warrant Canon releasing this as a product with a new badge on it? Would that make you buy it?
• Are you considering cameras from competitors like Sony, Nikon, Pentax, Olympus or others?
• Have you already purchased a camera from one of the competitors because it offers better performance in some way compared to what Canon is currently offering?... or is rumored to supply?
• Or have you had enough of the rumors of future Canon products, looked at available competitor's products, and still decided that it's time you tried a full-frame camera instead? (even though they have different trade-offs compared to crop sensor cameras)
Any other viewpoints you'd like to present, share and discuss are welcome, of course.
And Canon, watch this thread.
