Aside from 8MP, what features are in the 20D that you would want/need?
the 20D has eTTL 2(well I would actually if they dont change the body I would prefer eTTL 1 so it will work in my Ikelite eTTL 1 housing), Digic 2, faster to clear Buffer, better ISO performance, better AF. The big ones here for me is the ISO performance and AF
Looking at Canon's track record, I suspect that they won't allow the rebel to match the resolution of the 20D until they increase the rez on the 20D. Canon has consistently maintained resolution in direct proportion to price point and I don't expect them to alter that strategy now. At any point in Canon's history, the more you paid for a camera the more rez and image quality you bought.
As far as I can remember there has never been a relationship between Resolution and price with canon.
Pre August 2003
- 1D 4MP Price more than 10D
10D/D60 6MP Priced less than 1D
The higher resolution 10D and D60 cost less than the 1D
Canon prices between August 2003 and January 2004
10D 6MP 1500
300D 6MP 900
Clearly price is not a function of MP. The 300D has more MP but is costs 1/4 the price of the 1D.
Canon prices between January 2004 and August 2004
10D 6MP 1500
300D 6MP 900
For the past year the 10D and the 300D have shared the same image sensor with the 10D costing about 600 more than the 300D.
August 2004 to Soon(Based on the pattern)
20D 8MP 1500
300D 6MP 900
This Now the 20D and the 1D2 are the same resolution with the 1D2 costing more than twice the 20D.
Based on this track record if a new Rebel is announced soon it will most likely have at 8MP and will cost less than the 20D.
