With virtually no shutter release time-lag, almost anyone can capture the "decisive moment" without haphazard guesswork in RS mode. You will know immediately whether you got the shot you wanted. In addition to One Shot AF when the camera is set in its RS mode, you can also opt for manual focusing on the moving subject in Real-time. Except for the new Canon EOS-1v, manual focusing on moving subjects with the EOS-1N RS will give you a higher percentage of sharper pictures as compared to other 35mm SLR cameras. This series of photos below, of a maverick performance organized by Malaysia's national car manufacturer, Proton, was photographed using manual focusing with the EOS-1N RS in its Real-time shooting mode via Single frame advance. All but the third shot in the series were in focus. However, depending on the resolution of your Windows PC or Macintosh monitor, the difference may not be that apparent. First Second     Third - Slightly blurred Fourth     Fifth Sixth     Seventh Eighth     Ninth Tenth Yes, I could have just set the camera to its normal non-RS shooting mode and resorted to using AI Servo AF for the above series of continuous shooting but that would not have been any fun at all. Naturally, the series of photos presented in this page happened to be the best out of the three rolls of 36-exposure film, as I couldn't get a sequence of more than four continuous shots in focus for the rest of them. The rejected shots looked like the following: Either the first two shots were in focus, the next three not so, and sharp again for three more frames, or all blurred in the opening four, okay for the subsequent five and acceptably good for the remainder. This is one of the advantages in using the Canon EOS-1N RS, and this experience allows me to verify if I still have what it takes to be able to follow focus manually on moving subjects, after all those years of relying on the ultra-fast autofocusing system of the EOS System. Plus, I like the extra crispy sound that the double curtain blades of the EOS-1N RS make each time I click the shutter button to record the moment on film during RS mode. Yes, the EOS-1N RS uses a double-shielded shutter curtain blades as opposed to the single-shielded type found on the standard EOS-1N model. This gave the blades an extra protection to the film from the risk of being exposed to light leaks due to the semi-transparent pellicle mirror used. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 .
