Zach had a pending flag football night game and the following afternoon a swim meet this weekend and I had been thinking about the possibility of mounting my Canon EF 70-200mm f/4.0 L lens meant for my Canon 5D on my Canon XTi body. Used on my 5D at 200mm, this lens has an acceptable reach, but I’ve been curious about getting a bit “closer”. Thus mounted on my XTi (10 Mpx) with the smaller sensor, I picked up about another 40% in magnification, thus I had an equivalent of a 280mm lens. Seemed reasonable to me.
I had not played with this combination before as a telephoto image was not usually of much interest to me. But after looking at some of my sports images of Zach from last year, I felt it was time to try this combination out. And yes I did not want to purchase a fast 300mm for the 5D just for this occasion. I do crop my photographs and that could lead to potentially a similar image, but I felt it was better to get a higher resolution image before I started cropping. Second, the smaller sensor should be fine as for my personal family mementos, I usually do not print any larger than 8-1/2 x 11″.
So this back-yard landscape, above, was my initial image test with this combination at 200mm (280mm equivalent). The image is also slightly cropped after getting the horizon adjusted, so a good test image. Initially I was satisfied with this landscape when viewed in camera, thus I decided to use this camera/lens combination later that evening at the football game. Now looking at this landscape photograph after some PhotoShop tweaking, it confirms my suspicions that this camera/lens combination works decently together.
I knew going into the evening game that this had some limitations for a night sports event, e.g. the f 4.0 lens is pretty slow for this type of event photography, and the XTi did not have a lot of dynamic range for the sensor (e.g. push the ISO beyond 800 stats getting image distortion). Added to this I would be have to use hand-held exposures since I do not have a viable mono-pod for camera stability and support. Nevertheless, by carefully choosing to photograph at the right moment, this combination could obtain some interesting photographs of the action on the field.
