Summary: Size: HUGE Weight: HEAVY Solution: Work out and make some space for this lens! I have 3 DSLR systems and more than 10 different lenses, and this is one of my top two choices for everyday shooting. Being a prime lens, it isn't as versatile as a zoom lens, but being a macro at a wider 28mm, there aren't many shots you'll be missing. The milk and honey of this lens is in the picture quality.
Summary: It is an amazing lens, absolutely perfect videography. I use it on an AG-AF100 by panasonic (which is a micro 4/3 sensor video camera) and the depth of field it provides along with the light availability is amazing. If I didn't lose the ability to auto focus due to the adapter, it would be perfect.
