I have not heard of that lense before, so this one I have to check out and by. The rayxar lens cost up to 2000 dollar when it is in good condition. So if this lens is a cheeper alternativ it would have been great!
Have looked at your blog and liked it so you got your self a new follower :)Thx a lot @Armadilloman.
