I once bought a cheap, used Canon EF 24-105 f4 L lens with a scratched front element (2 scratches, ca. 5-10mm long and 1mm wide). Didn't even show at landscape pics with f/8.
I'm currently developing a pair of front mounted wide angle adaptors for use on the FF58 lens (which Is a renovated helios 44).
the first is a 38mm attachment (4 elements)
the second is a 25mm attachment (6 elements)
both are looking like they will be significantly more costly than a helios 44 due to the fact that the optical complexity and that the glass types are about as exotic as they can get. They are designed to impart as little image degradation to the helios and instead simply widen the fov, maintaining the optical character of the helios44. dont expect edge softness, ca or other nasties from these optics!
when released I will also introduce a 'Classic58' version of the Flare Factory 58, which will simply be a renovated helios 44 with uprated mechanical parts and a fresh external finish.
There are simply no wide options that match the helios44 / biotar look unless you go with the old OCT18 lomo lenses - of which none can be used on a standard ef mount, or with speed boosters. they're only adaptable to PL mount
