Looking For a Good Starter Kit?

So, we at Roberts know how hard it can be when you’re just getting going in DSLRs. You need a camera, and a bag, and an extra battery, and the kit lens usually isn’t enough, it all adds up quickly.

So, we’ve put together a special kit to help you out. We started out with the Canon EOS Rebel T2i, an 18 megapixel shooter with an impressive ISO range, high-rez LCD screen, and 1080p HD video recording. Instead of the usual Canon 18-55mm IS, we’ve paired it with a Sigma 18-250mm f3.5 – 5.6 DC OS HSM, which has over four times the reach of the kit lens and has built-in optical stabilization and hypersonic focus motors. Then, we’re throwing in a bag, extra battery, UV filter, and HDMI cable. Just add your own memory card (SD/SDHC, not included) and you’re ready to get shooting.

And there’s a video:

Zoomity-Zoom

Zoom is the stuff. At least as far as convenience goes. When I hired in, it was Nikon’s 18-200mm VR. We just could not keep that sucker in stock. That’s an 11x zoom (welllllll…. 11.111111 yadda yadda, rounding is our friend here.) Last year Canon jumped onto that game itself with the EF-S 18-200. 11x, that’s not too darn shabby there. The average point-and-shoot for years has been 3x.

We should really stop to talk about how unuseful “zoom” is as a measurement. The x zoom of a lens is found by dividing the longest length by the shortest. So, it tells you how much there is, but now where it exists between. Is the widest point 36mm, or 28mm? How long is that telephoto? 100mm? 200mm? Who knows? Zoom is a handy quick measurement, but it’s useless if you don’t also check to see where the limits are at.
