Hi There
Like Bill, I have a Nikon system and an Olympus system.
I can't really disagree with much that he's said - although I do find the focusing on the Olympus much more predictable than for the Nikon, especially with small objects reasonably close up.
The D200 (and the D2x) are much faster altogether - especially with respect to reviewing images. But I do have a few other points.
1. Build quality - the E1 has it in every respect (except for the nice rubber wheels on the D200), I wouldn't trust the weather sealing on the D200 (or the D2x) to anything like the extent of the E1.
2. Lenses - here I do disagree - as Bill said, there is a much greater range available for Nikon, and they're probably 25% cheaper for an equivalent lens. But I much prefer the mid range Olympus lenses, they seem to have an excellent price/performance ratio, but more importantly they have little or no distortion, and you can shoot them wide open with no issues. For ultra wides - I agree, the sigma 10-20 is a lovely lens, small, cheap and good quality - and I would think it's likely to be available for the Olympus at some point. With some exceptions I'm not a great fan of the cheaper 35mm lenses, and if you're going to pay for the pro lenses . . .
3. VR - I used to think it was a must, but the quiter (much much much qieter) shutter on the E1 seems to allow me to shoot at much slower shutter speeds than the Nikon, without worries about edge quality which VR causes, and (IMHO) unpredictable focusing results at normal shutter speeds if you've left VR on. If you're planning to use a tripod, maybe the Nikon is better, but if you're planning on hand holding, I'd go for the Olympus every time.
4. The future: Well, I don't think there is much doubt that there will be a new professional level Olympus during the next 12 months (even if it isn't announced at photokina). The professional quality lenses are there if you want (and can afford them).
5. The intangible: The E1 is wonderful to use, despite being slow and old fashioned and with limited resolution, it's just a joy to work with, and the results just make me say 'yes' the colours are always 'right'. I use it more than the Nikon gear, because I just like using it. . . . . and as a result, I take better pictures with it too.
6. resolution: Well, 10 is better than 5, no question IMHO 12-16 is about the 'right' resolution with good lenses. However, although it matters for landscapes, I don't think it's nearly as important for most other shooting (certainly the Olympus shines for close up and macro shots where the extra depth of field is a real bonus).
7. sensor cleaning. I never found it a problem, and anyway, the D200 doesn't seem to be very susceptible to dust - I've taken 10,000 with mine, and never done more than give it a puff with a blower brush. Mind you, it IS irritating having to remove a dust spec from 50 shots!
So, in a nutshell, If what you shoot needs speed, then the E1 probably isn't the answer, but if you want a compact system with incredible build quality and 'lovability' factor, the E1 has a lot going for it.
If you do decide to go for the E1, use some of the money you save to get the 14-54 rather than the (excellent but not weathersealed) 14-45. The 14-54 also has less distortion at the wide end, and focuses so close it almost doubles as a macro lens!
Bottom line - if someone said to me:
You HAVE to decide NOW is it to be Olympus or Nikon . . . . . . . I'd go for the Olympus.
Kind Regards
