Being a Canon fan I like to check upon this forum from time to time.
It strikes me that people just can’t make up their minds.
There’s simply too much choice.
I started photography since 1975 – well lets say just after “Camera Obscura” . First a Canon FTb and later a Canon A1. On july last year I switched to digital, knowing exactly what I wanted. Here it is :
1) Body Canon 350d
2) A battery grip
3) Sigma 18-200mm
4) Canon 300mm f/4 L USM IS
5) Canon Extender 1,4 II
6) Sandisc 2 Gb CF-card (RAW+JPG capturing)
It was eating away 3000 euro (I’m from Belgium) or about 2000 pounds but I can asure you that the results are VERY satisfying, even for a demanding person like myself.
Of course it’s too bad that Canon doesn’t make a 18-200mm like Nikon, Sigma and Tamron does.
Being an all-round (amateur) photographer the Sigma stays on most of the time. On shooting events I have no need to change. The Sigma is very versatile and easy to carry around. Of course according to light conditions you need to crank up the contrast, but as long as Canon doesn’t come up with his version, it’s the second best thing.
When it comes to the other “breathing” things (you know, animals and planes) I immediatly use the combo 300mm+Extender. If anyone preferes the Canon 100-400mm (for the same price) in stead of this combo I will not argue.
Bottom line, you get more then your money’s worth offering a wide range but bear in mind that both lenses need a good technique to shoot crystal sharp. Setting up the correct ISO is a delicate item. For me it is mostly set on 400 but never above. I do keep a very close eye on the given shutterspeed to match the technique. Even with IS on the 300mm you can’t afford being sloppy.
So, I hope my input can help out any struggling member.
