Can't decide which route to take. Like to hear from people with experience with these lenses. Currently have E-M5 + Pana 20, O45 and O75 Here is my thoughts and reason for confusion. Pana 7-14: ---------- I am a huge fan of the ultra wide angle view.So, on 7-14, I will most likely be using it as a 7mm prime.Having the ability to zoom is a bonus though.Plus the image quality is great.I love the images here with this lens. But, really worried about the purple blob/coloring.It will be really disappointing if that happens (from online reading, it seems that it happens for most E-M5's) considering the high price tag. Samyang 7.5 FE: ---------------- Not interested in fisheye view, the only reason considering this lens is the good image quality and ability to de-fish and the relatively low cost.It is much smaller in size too. But, not sure if image quality is affected much in the de-fish process and if all images can be de-fished to look normal.Also not sure whether composing can get tougher as you have to imagine on what it will look like after de-fish.If these are not a major issue, I like to get this lens as the price is much lower and the image quality is good. Pana 14: -------- If I get the fish eye, I need to fill in the gap between 7.5 mm and 20 mm, and hence considering 14mm. Overall, I like Samyang 7.5 + Pan 14 option, but really like to hear from people using these lenses.If you have Panasonic 7-14 and Samyang 7.5, I would like to hear which one you will cosider, if you have to get it again. Not considering O 9-18.Nothing against it, but, that 9mm view does not give that 7mm wow, at least to my eyes. Thanks for reading and appreciate your thoughts.
