I cant decide which lens to keep. I was planning on selling either my Panasonic 20mm or 25mm. I would like to be able to put the money towards the next lens i want to get, which is either going to be the 12mm samyang or a fisheye (probably the 8mm) I haven't used the Panasonic 25mm in a while and i first thought about selling that. I enjoy the results the 20mm give me, and I have heard that it is slightly sharper than the 25mm. However i still cant decide which one to sell and which to keep. In a perfect world i would keep both but because the focal length is so close it dosen't seem worth it to keep both. I think i could get around 450 for the 25mm, and probably 300 max for the 20mm, since i bought it used (maybe less, I would have to check) So i am asking, if you could only have the 20mm or 25mm which one would you take?
