If you use this lens on the EP5, how would you rate the combination. I love m43 for its size and know that this lens is very small compared to DSLR sized lens, but does it work as a "tripod free" lens with the ibis of the EP5? Does is feel very "wrong" for the EP5 when considering size? Have you done any BIF with larger birds like hawks and eagles? Thanks in advance for your responses.
