I officially declare this saga OVER!
I went to buy my Canon 450D from MS Color at lunchtime today. The lady there (Florence) was very nice and they put the screen protector on for me (I always get fingerprints or dust caught under them). Very good service.
I compared this camera against a number of other options. Most notably, the Canon 500D and the Nikon D90. My main problem with the Canon 500D is that it shares the same flaw as the 50D (they share a similar sensor)...noisier images. Sure, you get an extra 3MP (from 12MP to 15MP), but you sacrifice image quality. I've seen a number of side by side image comparisons between the 450D and 500D at the same ISO levels and the 450D, in my opinion, produces better quality images with less noise.
Of all the new features in the 500D, most of them I'm simply not all that interested in:
- 15MP sensor (more megapixels at the expense of more noise)
- High ISO (again, images are noisier, even compared between 500D and 450D at the same ISO)
- Movie mode (would never use)
- HDMI out (would never use)
- Face detect (it's a DSLR, not a P&S)
- Creative auto mode (as above)
However, there are one or two features which I really would have liked:
- 920,000 dot LCD: I've seen it and it does look amazing. However, battery life is reduced from 500 shots (quoted) on the 450D to 400 shots (quoted) on the 500D.
- Peripheral Illumination Correction: This only applies to JPEGs. I want to primarily shoot in RAW and learn how to do post processing. But it would be nice to have for the times when you want a simple photo and don't want to worry about post processing.
I even compared the 450D to other Canon models like the 40D and 50D. The 40D is a step down to a 10MP sensor and getting a bit heavy. The 50D shares the same issue with the image noise due to the 15MP sensor, and again is a little heavy.
The Nikon D90 was a very real option for me...I considered it many times. It feels lovely to hold, has a big, bright viewfinder, top LCD, more autofocus points, better kit lens, sturdier built etc. It's a little heavy, but not too bad.
The main reason I decided on the 450D over the Nikon D90 is due to the bit depth. The Canon produces 14-bit RAW files, while the Nikon produces 12-bit RAW files. Does this matter? It depends who you ask to some degree, but I personally feel that it is a definite advantage. You see, I want to learn how to do post processing and produce some fantastic looking images. Whenever you do anything done in post processing that results in losing information, it's better to start off with a 14-bit image because you can afford to lose more without degrading the image so much. A Google search will reveal all, but if you're interested, you could have a look at
http://www.earthboundlight.com/phototips/nikon-d300-d3-14-bit-versus-12-bit.html. It's just a single example.
I even looked at the Nikon D5000. It lacks an autofocus motor and the LCD screen is smaller. The grip is very small (my little finger keeps slipping off) and the gentleman at Cathay Photo told me that you cannot purchase a battery grip for this model. I know that the Canon 450D is just as bad to hold but I will buy a battery grip to solve this problem.
Another important factor in my choosing Canon is because I feel that they offer a greater selection of lenses which are suitable for where I want to aspire to (specifically, the L series F4 lenses).
So I've got my body, I'm getting my lens tonight, will get a dry cabinet tomorrow, and will get a battery grip before too long because it makes it so much more comfortable to hold. And at $880 for the body and $120 for a 6 week old mint condition kit lens (as an intitial stepping stone to better lenses), I feel that I've done very well from a value-for-money perspective.
A sincere thank you to everybody who took the time to offer some words of advice. I took it all on board and didn't make this decision lightly. Do I think I bought the best camera in the world? Of course not. But do I firmly believe that this was the best option for me in terms of budget, specifications, lenses and looking forward to future camera models? Absolutely.
P.S. Don't expect any snaps in the next day or two...I still have to redeem my 8GB memory card and bag from Canon before I can use it!
