I'm wondering if there's much of a difference in optical quality between the Super Takumars and Super Multi Coated Takumar lenses? I guessing the SMC lenses may have better colours and a little less flare but would there be much difference in contrast and sharpness? I'm planning on using some Takumars on my Panasonic M4/3 cameras but due to budget and time constraints, I may not be able to get a SMC version. Hope I'm not missing out on too much optical goodness?
