I was always in to photos. My mom was fortunate enough to get the Canon AE-1 when it first came out. It was like the cat's meow of the day. I loved the photos she took. My parents could tell I loved photography so they bought me a Kodak 110. Then I upgraded to a 35mm pocket camera. I was 16 years old and driving home from my girlfriends when I spotted a monster buck up on the ridge. I got home to find no one around. I grabbed my moms camera (A BIG NO NO) and headed up the mountain. I got to within 30 yards of the deer. I took several photos but it didn't sound right. I had no idea what speed or aperature it was on. I just pulled the trigger. Of course they all were blurred. My parents figured I needed an upgrade I guess so that I wouldn't use their camera so I got a used AE-1 with a kit lens.
I was a diehard and spent a lot of time trying to get close with my 135mm or whatever it was.
Finally I upgraded to a 600mm mirrored lens. I thought I could just snap pics. What they don't tell you is that the sun has to be shining bright to take pics with the thing. I got a few good images but most bucks and bulls are out at what time of day?

I got married and finally convinced the Mrs that I needed something better. I sold the AE-1 and the mirrored lens for what I paid for it. (WISH I had kept the AE-1), and bought an A2-E with a 400mm sigma. This lens was WAY better for light. I took LOTS of photos with this outfit, but ti was film and this was the dawn of the digital. Babies came and I was getting ancy. I talked to Pope and followed the likes of Tony on MM. Was I going to go Nikon now....I had the $1200 sigma lens. Now I just needed a body that took digital. I bought the Canon 40D.
I get home and put my 400mm on it and guess what. Though normally compatable, the chip doesn't work with the 40D. I found out Sigma did refurbish the lens, but the time had run out. Now I had the camera body but no glass....................
Long story short, I've invested in glass. Its taken mea long time to aquire it as it isn't cheap.
Thats my story. I've now been taking pics since I was 5 years old. I think I had a plastic camera before that. Thats 35 years of experience. It didn't just come overnight. The glass didn't either. A great way to try new lens is to rent them. REMEMBER bigger isn't always better when doing wildlife. Its also a matter of honing your skills and getting CLOSE. Even if thats learning and knowing your animal and figuring where they are going to go etc. I learned my lesson with that 600. There are big lens out there that take great photos, but the light they need or the lowest F stop makes them worth THOUSANDS and I mean THOUSANDS of dollars.
