I'm looking at getting one of the lower-priced lens adapters and I'm wondering what anyone can tell me about the comparison.

From their web sites, I definitely think that micro 35 is the more professional operation, and they offer the chance to go with the PL lenses somewhere down the line.

Also, I am shooting on an XL1 now, but that is likely to change in the near future to who-knows-what, so I am interested in portability.

Thanks in advance....

i use the letus35 with my xl1s. very happy with results. the unit is small and light. its like having another lens with you its so small.. you can fit it in an slr lens case

Exactly. Makes the overall camera look nicer too, instead of a bulky box for spinning glass. I love my letus.
