Prime vs. Tele
The only prime I own is my old Canon 1.8, metal mount, 50mm. Is there an advantage or disadvantage to primes? If I used a tele at the exact same focal length of a prime. Would I see a difference in image quality? I imagine if you used a 300mm prime, etc...you would rely on cropping the image to get the composure you wanted? Only having a crappy old 8mp 20d. If I crop very much. The image quality really goes downhill. I"m guessing it is pixel density of the sensor?

I have two. The 85mm 1.8 and the 100mm 2.8 Macro. The 85 is the sharpest lens I own by far. It's incredible. The 100mm macro comes in a close second, and it's good for a lot more than macro work.

The majority of my shooting is outside and involves motion or quick snaps. Do you use a prime at the dog shows? Backyard in the snow pics, etc...? Or just inside studio type pics?

Most, but not all of the back yard dog pics are the 100-400 zoom. Some are with the 100mm macro. The 85mm works really well inside when I set up lights.
I seem to shoot at the 400 end of the 100-400 often, which is why I'm considering dumping it for the 400mm prime. The 100-400 had a learning curve. You just can't slap it on your body and start taking great shots. DOF is limited at the 400 end for one thing. Another issue is it'll throw a bad shot from time to time for no apparent reason when capturing movement. The two snow pics below were with the 100-400. The little guy was standing pretty still. This was the 85mm @ 1.8. Notice the razor thin DOF. Bottom line, I LOVE my primes. LOVE them. I don't think you'll find a zoom half as sharp as a prime. |

I shoot using (9) lenses - (5) Prime and (4) Zooms...and if I know the basic focal length I will be shooting from I always go for the prime lenses first. Alot more flexibility in creativity when you know basically where the subject is going to be and distances from you to them is not going to change drastically. Shooting for example (below) using a fast wide angle lens opened up gives a look that is impossible to achieve by any other means. On the other hand if the object is moving fast or erratic then nothing beats the flexibility of a zoom in that scenario. Also if I'm shooting studio type stuff at around 6.3f-stop and up I almost always use my zooms simply because of the fact that at 6.3 the difference between a Prime and Zoom is almost impossible to differentiate. 24mm @1.6f 100mm @ 2.0f 35mm 2.2f 85mm 1.6f 50mm 1.6f |

At 3 FPS the 5D is extremely weak. Capturing someone walking is one thing. Capturing your dogs running in the yard will require a lot more than 3 FPS.
Maybe look at a 7D. That one does 8 FPS. A friend of mine has the 7D and loves it. |

I agree with Thomas. If you are looking to capture action get a 7D. An upgrade from the xxD line, but still a crop so your EFs lenses will still work. It would be a substantial improvement over the 20d. I also agree the 5D and even to some extent the 5Dii are not the best choices for action.

The new Sigma 24-105 F4 Art series lens is reviewed as good as or better than Canon L glass. Same with the 18-35 1.8.
