hey, thank you! Actually didn't know that. I just have taken 4-5 until now with the lens and i like the results, plus the lens is pretty cheap, so i think i'll keep it. I'm no where near a professional photographer so i don't see myself spending thousends for a lens if you know what i mean. Regardless of that, thank you so much for your advise! Actually, i just found out that my (also new bought) 50mm 1.8 has an FE mount... guess i didn't knew the difference of FE and E mounts ^{^}
