Got a query here. I recently got a 2nd Hand Raynox DCR-250 and use it together with my 50mm f1.8 and seems like the result is ok. However, i am thinking of getting closer. So i was thinking, should i get a +4 Close up filter to optically get closer to my object? Will it help? I am rather concern abt the softness on the side of the lens if i use a close up filter. I tried the Raynox with my 18-135mm kit lens and its really soft on the side. So please advise ok?
Also, if i use a closeup filter itself on my 50mm, how will it affect my focal distance etc? Please advise~~ Thanks in advance~
