優點:
If you're in the Canon system and want a new body, go for it. There is no better LCD on any other Canon SLR, and weight and handling are the best Canon's ever offered.
缺點:
If you're looking, the image files from the Rebel T1i looks poor at large magnifications. The common technical issues of noise and resolution and sharpness are fine. The problem is that the noise reduction is so strong, even at low ISOs, that while sharp edges remain sharp, even moderate textures get smoothe⋯⋯d over.To the educated observer, this makes the Rebel T1i images look as if they came from a point-and-shoot, with their need for severe noise reduction even at daylight ISOs.This makes T1i images look slightly weird because the edges are all sharp, but distant bushes will have no texture, similar to cartoons...Don't freak out; this is a subtle effect, but annoying once you learn to recognize it. Dealing with raw files instead of image files (JPG) may let you rectify this later in software; my life is too valuable to waste playing with raw files.
This wouldn't be a problem for Canon if all DSLRs did the same thing, but if you worry about this, Nikons are a world better. Doing a direct comparison at my classified test range, results from a D300 look worlds better at 100%. The D300 looked like a real photo, and the T1i looked like a smudgy point and shoot.Heck, w⋯⋯hen you add in the Canon's potential for autofocus misses, even some comparison shots from a 6MP Nikon D40 with its included free 18-55mm kit lens blown up to 15MP look better technically than the T1i and 18-55mm IS lens.
If you really want to split pixels, you will need very good lenses. Unlike Nikon, Canon cameras cannot and do not automatically correct for corner color fringes. The 15MP setting of the T1i does a great job of letting you see minute limitations in your lenses more than giving you more details.Sadly, the potential for A⋯⋯F system "misses" and Canon's inability to correct lateral color fringes due to lens limitations means that if you like to look at everything at 100%, the T1i looks a lot worse than a Nikon like the D5000, D90 and D300. These Gen II Nikons automatically fix these lens flaws, so the resulting images from Nikon cameras, if you're looking at 100%, are much better unless you're shooting $2,000 tele lenses ($2,000 wide zooms still need these corrections).
Canon cameras can't fix lens limitations. While modern (Gen II) Nikons eliminate color fringes automatically, any defects in your lenses will remain in your photos with the T1i, and if you're looking for them, 15 MP is going to show them on most lenses.
I still prefer Nikon. I still find my Nikon D40 easier to use and carry, and it costs half as much. The results are about the same. I can pull great images out of any of these cameras. If you demand more pixels and count every one, the Nikon D5000 (or equivalent D90 or D300) gives superior technical results from their ⋯⋯lack of noise-reduction induced smudging, ability to correct lens defect color fringes and more reliable AF system. If you look at your photos at 100% on-screen, the Rebel T1i images look more like they came from a compact than an SLR. If you already have Canon DSLRs, the T1i is a winner. I wouldn't buy one, but that's because I already have a 5D Mk II and a Digital Rebel XTi I never use and I prefer Nikon. If someone offered to trade me a T1i for my XTi, I'd do it in a second.
It's a great lens, but has one potentially serious flaw in the AF system for many users. The Canon 18-200 IS has the old AF system that moves the focus ring as the AF works, so you have to keep your hands off of it as it moves.Worse, cannot turn this ring for manual focus unless you first move a switch to disengage the⋯⋯ AF motor.This is a serious shortcoming compared to Nikon's 18-200mm VR, on which you the focus ring never turns unless you move it, and which you may move at any time for instant manual override.On this Canon, the AF mechanism is far more primitive. It's quite a pain to have to stay clear of the focus ring during AF, and have to move a switch to get to manual focus. Poo.
