I just picked up this lens, and I am happy with color and contrast. It is sharp! I took a look at the cost of the Canon tripod mount and it runs about $139. There are less expensive mounts that range in price from $13-45 or so.
Are any of the less expensive mounts worth looking into? I would hate to lose a good lens, because I stuck it into an unreliable tripod mount.
There is an inexpensive one by Opteka and a more expensive tripod mount by Fotodiox. Of course, there is the Canon tripod mount.
Does anyone here have experience with mounts, other than Canon?
