I do welcome 3rd party lenses where they either provide something better than the original, or do a good enough job for much less cost. But 3rd party compatibility remains a potential concern.
Recently it came to light that various [url="http://www.canonrumors.com/2010/11/tamron-lens-phenomenon-update/"]Tamron lenses wont function fully with the outer cross type AF points on mid range Canon bodies[/url] as it appears they used the same lens ID as ancient Canon lenses which also do the same. And on Sigma, their lenses have [url="http://www.sigma-photo.co.jp/english/news/info_100910.htm"]trouble with the Sony Axx range[/url] unless updated. Credit to Sigma for offering a free update, but you have to worry which lenses are supported, and for how long?
