در مورد 30d با تمام تعاریفی که ازش شده این اشکالات هم گفته شده:
این مطلب تو سایت dpreview.com هست :
It wasn't surprising to see a certain level of disappointment among existing Canon owners in the evolution that is the EOS 30D, I'm sure some were at least expecting a nominal megapixel upgrade as well as the changes included. I happen to agree with many who suggested that the EOS 30D should really have been named the 'EOS 20D Mark II'

The 40D features a pretty big jump in speed and performance over the 30D.
This brings us to an interesting question: how many people out there would blaze through 75 rapid-succession photos at 6.5 photos per second?
The real point here is that the Canon 40D will ALWAYS be ready to take the next shot, regardless of how many photos you've just taken.
There are three common features emerging on all digital SLR cameras - what I like to call the "digital SLR trifecta": dust control, image stabilization and a live view LCD.
The Canon 30D has none of these extra features - although with Canon cameras, image stabilization comes with the lenses not the camera - so you can get stabilization for the Canon 30D if you buy the right lens.
By comparison, the Canon 40D includes Canon's new dust control system (Canon EOS Integrated Cleaning System), and it has a live view LCD screen - a feature that was previously only available on the high-end (and extremely expensive) Canon EOS 1D Mark III
Another nice D40 feature is the ISO display in the viewfinder. The ability to change ISO on the fly is one of the most powerful features of any digital SLR camera

The EOS 40D is much more than a minor upgrade of the EOS 30D. It's basically a new camera with a new CMOS sensor, a new 14-bit processing engine, a new AF system and new features such as Live View, Highlight Priority and High ISO noise reduction as well as improved ergonomics with the enhanced 3" LCD. Though it looks much like the 20D/30D it has a more "professional" feel - though I'm not sure why. Perhaps it's the quieter and faster shutter operation that simply makes it sound better!
In just about every respect the EOS 40D technically outperforms the EOS 30D and so I think it is a worthwhile upgrade for those who can afford to switch and who can use the new features. I didn't feel that way about the 30D, which was a good camera but for me didn't offer enough new features to persuade me to trade in my 20D and upgrade.
The EOS 40D is the best yet of Canon's prosumer line of DSLRs (D30, D60, D10, D20 and D30). Each has offered more features than the last, and done it at a lower price. The EOS 40D ($1299) clearly follows in this tradition. It's a very good camera and I can recommend it. I didn't just review the 40D, I bought one myself, so that should tell you something!
راستش نظر خودمم رو 40d هست مخصوصا بعد از ویدیوهایی که تو youtubeدیدم دیگه هرشب خوابشو میبینم
تو forum کسی گفته بود که 40d رو 920.000 با گارانتی ایده آل خریده ،برای Sandisk Ex III CF 8 GB 133x هم که 75.000:::: با 500.000 چه لنزی مناسبه ؟
