My main camera is now the Nikon d80 (having upgraded from my Canon G3). I've had it only 10 days or so, but so far we're getting along just fine. I've experienced the same problem as many other d80 users - namely that it has a habit of overexposing (apparently it exposes for the blacks in the picture) but a quick adjustment on the exposure meter sorts that out. Other than that, no problems at all.
So far I have one lens - the Sigma 30mm f1.4 - fortunately I love it. I wanted a fast lens for shooting some of the geek events I attend as light levels can be pretty variable.
I also have the Nikon AFS DX VR 18-200mm f/3.5-5.6G ED IF on order.
Once I've got used to these lenses, I'll determine whether I need a more wide angle lens to add to collection.
I have one filter for the Sigma lens (62mm) and that is a UV filter. Over time, when I've worked out which lens I'm using in what circumstances I'll get a polarising, a Neutral Density and maybe some close up filters. I already have a 72mm UV filter ready for when my 18-200mm lens shows up.
So far I have the following:
I've used my non-camera Crumpler bag a lot over the years, and it has just kept on going. So, I thought I'd give the Crumpler Pretty Boy 4000 XL a try. It looks fantastic, and fits everything I need (at the moment) into it without a problem.
