Who is disappointed with the Oly 45mm lens?

If it ain't broke I am not trying to fix it.  It has worked even when I shot Nikon and I appreciate your input, but this formula of not mixing body and lens manufactures when possible has worked for me for a good part of 20 years flawlessly for a SLR/DSLR and the like interchangeable system.

Olympus may have great lenses and options, but I see Panasonic doing a great job inside Panasonic today.   I don't feel the need to look elsewhere when Panasonic has it covered as it exists today.
