The last time I was researching a DSLR, I stopped at looking at a Canon EOS 60D versus a secondhand 50D. So I can't give you any specific models, or updated information; so I'll be limited to giving general advice at what to look for.
1- The ability to take real close up macro work. And i mean real close up not some shit it can read text on a page.
2- The ability to make the back ground blend with the foreground crisp and clear
3- Shit hot night time shooting with the ability to show of UV light in a dark room
4- The ability to take Hi Def films
PC's and liquids for web site use
Show PCs
1- Extreme close up shots of PCB's
1- 90% of work will be done on tripod and light ten
5- Any suggestions guys and all so the lenses must be cheap as well as the battery's
6- Will save up about £500 to spend (next month)
1: Indoors, tripod, still life subject; good. You more or less only need to worry about lighting and lenses. Maybe for a extreme close-ups, a lens-mounted ring light would be an excellent idea; nothing overly fancy as long as you set the white balance first. Shoot everything at low ISO, shutter speeds, and utilise the shutter release timer as your remote shutter release to take your photo after all the button pressing related vibrations have passed. Low ISO and shutter speeds lets you let in more light over a long time; the lighting just soothes out better, and as a bonus you get less noise dirting up the photo.
2: For a blurred background or foreground, you'll need to set the aperture (f-stop) on the lens to the minimal. Having a low f-stop shortens the depth of field of what's in focus, it also widens the aperture hole inside the lens to let in more light, thus enabling even slower shutter speeds. Since you're on a budget, you probably willn't have much choice in the quality of bokeh (Blurriness. Yes, people paid extra money for more blurriness) you can achieve with your lens.
3: Combining the first to responses; use a very low ISO, wide open aperture (low f-stop number) and set as slow a shutter speed as you need in the dark. One second, ten seconds, half a minute exposure? why not, whatever is needed. You can use a flashlight with a diffuser (eg. tissue paper) to add some creative fill light during the exposure. But if you're trying to capture your fluids with particulate without motion blur, then you'll have to play around with a flash or speedlight and faster shutter speeds.
4:
I dunno. It's very camera dependant if they have 1080p video function, but the more recent cameras usually can do Full HD video.
5: If you're shooting indoors in a studio like environment, maybe you can look into a AC adapter to power the camera instead of running off the batteries.
6: That's quite a tight budget, but workable. Definitely looking at secondhand gear to save. I see that Sony Alpha cameras are doing good things in the entry price range. Spend your money on the lens(es).
