I am getting into event photography and want to also expand with portraits, seniors and weddings. My budget is limited at the moment and have a few questions in regards to lenses.
This summer I shot a number of tennis tournaments with my ef 28-135 IS lens, which served well. However, I am considering eventually selling that one and getting the 24-105 f4.0 L lens. That is a quality lens which could be used for other venues, obviously.
General question is this. Will the quality of the L lens allow me to crop aggressively and to what degree? Will such cropping be more than adequate in making up the difference in focal lengths of the two lenses? Is the 4.0 a fixed aperture and what difference can I expect versus the 3.5-5.6? I can moderately crop with the 28-135 lens and still get good 16 x 20 and yes even 20 x 30 prints. This was very surprising as articles suggest that IQ not possible, much less at the low and medium pixel setting on my 30d, as shot.
Also, why can't Canon make an 18-200 2.8 L lens???? Your left debating between the 18-300 L and 70-200 2.8 L. Just venting on that one as my desired lens would serve better with the sports I wish to shoot, without having to change lenses.
