I bought the Oly 75 with my E-M5 from the Buy & Sell forum for a pretty decent price. I bought it because of it's prestige and light-gathering ability. I have captured some images that I am pretty happy with. I just don't seem to use it that much. It seems to fall in a length that is a little too narrow for what I typically shoot so I just don't find myself picking it up. I understand that it is a favorite of portrait shooters, and I tend not to shoot portraits that much. On the other hand I like to shoot close focus nature shots with my Oly 14-150ii and MCON. I like the versatility of the 14-150 and ability to easily add or remove the MCON. But sometimes feel that I left a little something behind by not have a faster lens. That got me thinking, should I replace the 75 with the 60? The 60 isn't that far off in length, but adds a great deal for close-focusing or macro. It is also weather-sealed so I shouldn't have an issue hiking with it. But, I would be giving up the versatility and adding back lens changes - which is why I went to the 14-150ii in the first place. Thanks for you input!
