I am pretty much a rank beginner when it comes to real photography. I've owned and used cameras for many years but they were mostly used to document travels and trips to the woods and streams.
I am a fisherman that always carries a camera, but one who rarely uses it. I'd like to get beyond that point and record some of the things I've seen heading to and from my fishing destinations.
To that end I've outfitted myself with a modest kit consisting of a well used but fully functional EOS20D, as well as a 15-85 IS USM, and a 70-300 IS USM, both purchased new. I also have Corel PSPro4 to help correct things.
I often take breaks while I travel to fish to watch and observe birds and animals I see along the way. With the 70-300 I find that I am often too far away to get the scene I'd like to get. To solve that problem I'd like to add a lens with longer reach.
With that goal in mind I am considering purchasing either a Canon 100-400L IS USM, or a Sigma 150-500 OS. Both lenses are on sale right now with a little over $ 300.00 separating them.
I have no goals or desires with my photography other than to hopefully record an occasional aesthetically pleasing picture to serve as a reminder of where I've been and what I've seen. Might I decide to pursue things further, I don't know? But I do know that I have pictures of nice bucks and bear or two that would look a whole lot nicer if I was shooting from 25 to 40% closer.
Personally, I am leaning towards the Sigma. The extra reach seems attractive to me but I'd like to hear from other folks.
