Nice close-ups. You might want to consider setting your exposure compensation to -1 or -2 for the black-dialed watches, though. A polarizer can also be useful in cutting down some of that glare, assuming your front element doesn't rotate w/focus.
I'm using a cheap Quantaray (Tech 10 Macro 1:2.8 ), definitively not great but gets the job done. I have it since I had my D70, and now with my new D90 I hadn't used it yet. So what better then to do some unpretentious watch shooting (= lying on my belly in the backyard) to test it out ;D .
w70p, that's a good idea about reducing the exposure. I was shooting in dusk, so it didn't occur to me to reduce the exposure. That's the beauty of digital photography: it's so easy to test and experiment!
Nice to see another D90 fan! I think this camera down right ROCKS! You get almost professional features but with a hobby price with the "kit" (body + 70-105 mm lens). Since the camera is really good, it's worth investing in some good lens, and that's basically only two: a 300 m tele (or more, if you have the mula) and a macro (if you want/need to get real close ups). And of course, a flash. The built in one is just ok, good for outdoor stuff, but it really lacks if you want to do some good fill-ins. I'm looking forward to getting a SB400 or maybe even a SB600 if can scrap up the extra 100 bucks.
