V3 is very nice. Labeled with “cheap construction”, something I never understood… until I opened it up. And indeed, the departure from the Rigid V2 is huge: the V3 internal construction is cinsiderably cheapened vs the V2. Basically lotsa aluminum and less brass. But no plastic as with the canadian V4.
The V3 has a very loooong focus throw while the V4’ is very short.
The V4 optics are arguably a big step above the V3, all incremental improvements but very present throughout.
All in all, the V4 is a real upgrade to the V3: a thing proven by its now 50 years strong design.
The V5 corrects the V4’s somewhat cheap construction while keeping the same optical tamed perfection.
In conclusion, as has been said many times: any Summicron is a perfect Summicron.
