I would love to do macro pictures on spiders and such and pictures of my german shepherd that will soon be in agility competitions (fast pace). I new to understanding the types of lens and their abilities.

You need fast focus to catch a dog running, but dedicated macro-lenses are slowing focusing.. by nature. 70-200 f/4L would be great, or for prime.. 85 f/1.8. Kel

Sorry if my original post looks goofy.

Ultimately, I would like 3 lens to start off with (other than the stock). One would be for semi distance around 50 meters or so for my dogs agility competition and fast action play. For this lens I would also love to take gorgeous landscape photos, birds, skies, and possibly planes moving in the sky and such, The second lens would be a typical lens for inside (short distance) and backyard distance. The last lens would like to be a micro lens for spiders (and similar sized insects), water droplets, and small fish/ organism in my father marine aquarium. Any help would be For distance look at Canon 100-400, 70-300 or 55-250IS, for macro look at Tamron 90mm 2.8, Canon 100mm 2.8, Canon 60mm, etc. For everything else the "stock" lens 18-55IS is pretty sharp and expect to pay a lot more for better zooms, e.g. Canon 17-55 2.8, Canon 15-85, Tamron 17-50 2.8, Sigma 17-50 2.8, etc.

Thank you for taking the time to reply. I don't have a budget, but I don't like to spend more than 800 bucks on a lens. Now, I have a basis to go do some reviews off your recommendations.

I think I would go for the 70-200 f4 for the reach and AF speed (if it is anything close to the IS version) and a set of 3 extension tubes for macro ($80). Edward Jenner

EF 70-200mm f2.8 IS lens with 25mm macro extension tube. EOS-3 camera, Ektachrome film. Settings unrecorded. Tripod, 550EX fill flash and ambient light. But if you want to get closer, you might want a true macro lens such as the Canon EF100/2.8 USM...  EF 100/2.8 Macro lens at f11. EOS 30D camera at ISO 200, 1/200 shutter speed. 550EX flash. Handheld. Or a Tamron 90mm...  Tamron SP 90mm f2.5 Macro at f11, vintage lens adapted for use on EOS 7D at ISO 400, 1/400 shutter speed. Ambient light, handheld. But macro lenses tend to be relatively slow focusing and the 70-200mm will be a whole lot more versatile for non-macro, action shots....  EF 70-200/2.8L IS at 105mm and f4. EOS 50D at ISO 400, 1/400 shutter speed. Handheld, ambient light. The 70-200 won't have any trouble keeping up with fast moving subjects...  EF 70-200/2.8 IS at 100mm and f16. EOS 50D at ISO 100, 1/50 shutter speed. Handheld, avail. light. Though at times you might want something longer...  EF 300/2.8L IS lens at f3.2. EOS 7D at ISO ISO 1600, 1/2000 shutter speed. Tripod w/gimbal head, available light. Or a even longer...  EF 300/4L IS lens with EF 1.4X II teleconverter, effective 420mm & f5.6. EOS 50D, ISO 200, 1/1600 shutter speed. Monopod, available light. Or you could choose to use some prime lenses, if you prefer...  EF 85/1.8 lens at f5.6. EOS 5D Mark II at ISO 400, 1/400 shutter speed. Handheld, avail. light. With T2i, the 70-200/4 will likely balance better than the f2.8 version. However, an f4 lens is going to be less useful in low light situations and might be less quick focusing than an f2.8 lens. If at all possible, I recommend getting the IS version of 70-200 (or longer)... it's really nice to have stabilization on these longer teles, especially when using them on a crop camera like yours. Previous posts have mentioned some good alternatives, the Canon 100-400 IS for example. You also might want to consider the Sigma 120-400 OS and 150-500 OS, which are $500 or so less expensive than the Canon. All these lenses are f5.6 or slower at their longest focal lengths, so will generally be most useful in good daylight. With your T2i, you will probably want to select the center AF point only, when shooting fast moving subjects. It's a more sensitive and responsive "cross type" sensor. All the other AF points are a less sensitive and slower type. AFAIK, no one makes a single 50mm or 60mm macro extension tube for Canon EOS (I have one in Canon FD mount, tho). And stacking several macro tubes together tends to slow focus for a couple reasons.... One being the additional electronic connections between each tube. But another reason is simply light falloff within the tube, which is unavoidable with more extension (light falls off exponentially). However, with macro often focus speeds isn't an issue. It's often easier to just use manual focusing techniques. More of concern is controlling the aperture electronically. The $80-90 extension tubes are plastic and might flex a bit, causing electronic connectivity problems. The more expensive (about $180 US) Kenko tube set are sturdier metal and a tiny bit longer (12mm, 20mm and 36mm vs 11mm, 21mm and 31mm for the cheaper ones). Canon doesn't offer a set, but their individual tubes are also quite good, though a bit expensive (25mm is $140, 12mm is about $90). Indoors, low light and shorter focal length.... Consider the Canon 28/1.8, Sigma 30/1.4, either Sigma or Canon 50/1.4.... Or if it will only occasionally be needed and used lightly, the inexpensive Canon 50/1.8 (slower and less accurate focus, not quite as nice image quality... but it takes much better photos than it should, considering it's low price).
