For me, as the R8/9 are already fairly big any new lenses should be short .[ I'm not too bothered about the width of the lenses, or within reason, the weight]. A new f/2 or f/2.8 Asph 24mm and an f/4 Asph internal focus 180mm, would do nicely as long as it was the same size as the old 180mm f/4. I found this lens very useful because of its very small size, and was always carried, but the position of the focusing ring turned me off of it.
