I'm using Canon Rebel XT, but the first one and the last one are from film and Rebel Ti. Closeups are made with Sigma 70-300 DL and Sigma 28-80 lenses, (were about US$220 both (new) when i bought'em three years ago, the 28-80 is no longer in production, alas)
Moon is more complicated. It was taken through an old Soviet-made (USSR, Soviet Union, communist evil empire, anyone remembers?

)) mirror 1000 (one thousand) millimiter lens. It is 12 cm diameter 1,5 kg monster

there are adapter rings available to stick those old ones to Canons - or, in this case, attach a Canon to it

You can take a look at a bunch on my pics
HERE - they are all made with these cheap Sigmas, including all macros, with some exceptions for Canon 28-135 IS. A good portion, at least 50% of all shots, were made with my old film camera with the same lenses.
