Balancing it All Out
Thursday, January 31st, 2008
Seems like there is a theme developing this week. Me taking pics with my 300mm lens. Well I grabbed my camera and went off for my walk today. I still don’t feel too comfortable using this lens, so I decided to keep using it. Hopefully I’ll get better with it before too long.No sooner did I get out of my complex, did I see this iguana. It was hanging out on a hedge. I’m not sure how I noticed out of the corner of my eye as I was walking. It was green and blended in with the greenery of the hedge. But there it was.I just assumed it would run away as soon as it saw me looking at, but it didn’t. It just sat there sunning itself. I knew he was looking at me, because I could see it’s eye following me. So I started to slowly move in closer. I didn’t seem mind too much. He still just sat there happily in the sun. I moved in closer and closer, but the thing just sat there. So I started to take some pics of it.Ok…so I remembered what I learned yesterday about using this lens. Try to hold it steady, and to keep a high shutter speed. That way the shutter opens and closes quickly, giving me less time to shake the camera and lens. So I did set my shutter speed higher. But the price for that(again….nothing is free), is that I have to open the lens aperture up. When the shutter stays open for less time, you need to compensate with a bigger opening in the lens so the exposure is correct. When you use a bigger opening, you get less of the pic in focus.So now I had to balance those things out. Trying to get the steadiness that I needed, with the quick shutter speed, with the amount of pic that I wanted to be in focus. Anyway, the result of my attempt is the pic above. How did I do?


The longer the barrel the better the aim. Ever hear of that old saying? I’m not exactly sure I know what that was supposed to mean, but today I discovered it might not be so true in photography.For past few mons I’ve been shooting with my 35-70mm lens. Of the 3 lenses I have for my camera, this is the best of the lot. So I’ve been using it the most. Well today I decided to change things up a bit. I took the 35-70mm off, and put my 70-300mm on. At 300mm this lens gives me almost 3 times the reach of the 35-70. Meaning that this lens will magnify the image 3 times bigger than the 35-70 lens could.The first thing I noticed when I put the 70-300 on, is that the set up is much lighter. The 70-300 is a much lighter lens. Off the camera and in their neutral positions, both lenses look about the same size, but the 35-70 is much heavier. It’s a better quality lens, and you can tell when you pick it up. So when you carry the camera with the 70-300 it feels like it’s lighter and easier to handle.Well after shooting a few pics, I notice that the 70-300 extends as you zoom in. So as you zoom towards the 300mm end, the lens extends and gets longer. Which brings up another old saying……can it ever be too long? Well I’m not sure what they had in mind when they made this saying up either, but I’m here to tell you that yes……… yes it can be too long, when it comes to photography. The longer the lens got, the more unstable the camera lens set up became.Despite the fact that the set up was lighter, the length of the lens changed the center of gravity of the camera and lens. I had much more camera shake with this longer lens. Another thing is that the 70-300 lens magnifies the image 3 times larger. BUT when it does that it also magnifies your camera shake, so the shake appears to be at least 3 times larger as well.Oh well I guess nothing is free. For a larger image you pay for it with more shake. I’ll have to go out and practice with this lens more. But in the mean time, at least I was able to disprove two old sayings.
