Would you bother with the 12mm F2, 17mm f1.8 or 45mm f1.8 if you had the 12-40 f2.8 Pro?

Sad but true, buying a new lens tends to get me motivated to go out and take more photographs!

I have the 12-40 f2.8 pro that stays on my camera pretty much full time. I have the 9-18 that I use occasionally. I also have the cheap Panasonic 25 f1.7 that I bought for $99, I'm not too fussed about this one so it might go but there are loads on the online markets so not worth much. I have the cheap 40-150 that gets occasional use. My last lens is the 75-300 which is rarely used and seems like a bit of a white elephant for me. I am tempted to sell the 75-300 to get either the 12, 17 or 45 but not convinced I will use it!

My last thought is that I should ditch the 9-18, 25, 40-150 and 75-300 and get the 40-150 f2.8 pro plus the teleconverter that is fore sale reasonably on an online trade site!

Would you put all your eggs in the two 'Pro' zoom basket?

I own the 12-40 PRO, and recently purchased the 45mm f/1.8.  I find it to be a valuable addition to my lens arsenal, especially given the discounted price, and my experience thus far with it in low light situations.  And as for the 40-150 PRO and teleconverter, which I also own, well that one produces quite fine images.  With the exception of the 45mm and the 40-150 standard grade lens I just got today with a new in box E-P5 from Adorama for $399, all my eggs are in the PRO line up, including the ones above and the 7-14mm PRO.  That's all I am getting, money does not grow on trees.
