Thanks,the cameras a canon 400d eos with a 100mm 2.8 macro lens.I think the canon 400d has come right down in price now and has been upgraded by a new dslr camera but i like the 400d and cant see a reason to ever replace it with a newer model.
I use a high f number so i have to use a tripod on all the stock pics i take ,when doing the top downs i use a small custom made tripod that sits on a glass shelf in the water also custom made because i still use a f number of f22 so there would be a lot of camera shake without a tripod.
