Since tamron and sigma doesnt have the fastand reliable AF like the L lenses I wont buy them only for MTF charts. BEcause ı manly shot on the streets and I need very fast AF to catch the moment. Color, contrast and characteristic look of the images mean much more to me than the MTF charts.
May be that's not the case so much any more. Tamron and Sigma have both made huge advances in the last couple years. Not only in image quality but in focus speed and accuracy as well. I think that the one part of the equation that is missed in general with third party lenses is the perception that they are small companies/manufactures. Don't have any idea how many lenses are sold by lets say Sigma, but based on the fact that you can go to Canon, Nikon, Sony and Sigma forums and read about Sigma lenses and the great new products they are producing would indicate they are producing a boatload of lenses. So, based on what they produce and the volume it would seem that it is only a matter of time before they overtake Canon and Nikon in the lenses arena. Their profits all go back into lenses R&D, not so much into trying to develop a new body, sensor, shutter etc. for multiple lines of bodies every year.
I think the general perception is that Canon and Nikon are the big guns and everyone else builds their products in a basement in Shanghai. I believe that there have been several shots across the bow of the "big guys" lately and that the tides of change in the lenses industry are changing quickly.
Soon Canon will no longer to able to put a red ring on their lenses and charge a premium over the third party guys. Canon has had the corner on the market for far to long and this change should wake them up to market reality. Me, I am slowly building a great kit less any Canon Ls. May not be able to get to the goal but so far I am more than happy with the results from the Sigma, Tamron and Canon non Ls.
More importantly, the budget and wife are happy..
