It's hard to believe there's a sensor problem, but it's not hard to believe there's a marketing problem. With a product line with four
offerings between $800-1800, why compound the problem. If you assume the Rebel line will be the $800 entry point and that the
6D at $2000 beings a new classification - full frame - it would appear that a single offering in the middle at the $1400 price point would
be an adequate answer. Then what do you do, kill the 60D or the 7D replacement? It's not so much a competitive issue, Nikon is weak
in the same price area, Pentax has an offering, and who cares what Sony offers? Basics - metal body for ruggedness, better AF than
current models (or else why change), between 18-22 megapixel image, SD card (single or multiple?), 7-10 frame/second exposure rate,
weather sealing (big plus in this price range), better control software (another impetus for change) with better menus and more intuitive
operation, HDR processing, and while not particularly desirable for me but perhaps required for successful marketing - video capabilities
that are better than Rebel (not much of a hinderance) and maybe even match the 6D since the software would only require a minor
tweak. Then on to a much bigger issue than a high end crop sensor body, but a commitment to a high quality EF-S lens stable. As a
previous posted suggested a higher quality 10-22 would be a good start, a 28 or 35mm f1.4 prime (in the $600 price range a'la the
Fuji X series), a ruggedness improvement to the EFS 55-250 would be a welcome addition, especially if the lens could be a constant
aperature f2.8 (or 3.5) and a prime in the 85-100mm equivalent range at f1.8 or 2.0. Use the new STM motors and you have some
incredible offerings.
