When you get the lens to focus accurately,
you will be amazed at the picture quality it is capable of producing, like the examples
below.
All the pictures shown in this issue were shot with the EOS-1N RS, which lost 2/3-stop of light that reached the film as compared to a standard EOS-1N model at the same ISO film speed and lens used. Generally, the EOS-1N RS, being a pro model, is hardly a camera that will be used with any of the variable aperture EF zoom lenses meant for mostly beginners and amateurs. With other EOS models that do not utilize the semi-transparent pellicle mirror as the EOS-1N RS, it is much easier to shoot available light pictures when using a variable maximum aperture zoom lens. But this 2/3-stop of light loss with the RS model also made it easier for me to test out the EF 70-210mm zoom lens to the limits as I was be able to measure lowest shutter speed usable, handheld before any camera shake became apparent in the pictures. Then again, with a non-moving pellicle mirror, one can argue that the RS will be able to handle slower shutter speeds handheld without risking camera shake than any of the EOS models available to date. That may be true but as can be seen below, these four photos were all shot at 1/30 sec. at f/4.5 with the EF 70-210mm lens set at its longest end. The abstract shot of the Sultan Abdul Samad building, being a stationary subject, was quite easy to shoot. On the other hand, slight movement by the mobile female hawker caused a slight amount of softness in the image but better definition on the table and wares.
As mentioned in the previous page, an "ageing" EF 70-210mm seems to have a slight problem to get the focus right in One Shot AF mode - the final two photos from above are such examples. The first shot, although I did aim the AF sensor (center point was used) at the motorcyclist (in blue helmet) and his pillion, the focus seemed to be set at the rider behind them. In the next try, I managed to get both of them in correct focus. Text and photos by Philip Chong. Copyright 2000 by Canon Marketing (M) Sdn Bhd << Back to Main . 1 . 2 . 3 . |
