I always was curius WHY Variable Primes wasn't succesfull in the market ..
1. They have the quality of a fixed lens
2. They are extremely time-saving ... No changing lenses for finding the right focal length .. or changing lenses with different focal length
3. They also can be used as a PARAFOCAL MINI-ZOOM (ok very short zoom .. but still zoom)
-Many accuse them for their weight .. But if you compare (for example) Master Primes it's not a big deal ...
The VP1 16-30 weights 4.4 kg and the Master Prime 21mm weights 2.4 kg !!! Also in NOWADAYS with the digital cameras weight isn't a problem (even for steadys)
-Also isn't a shame that the OLDEREST Standards Primes 2.1 are in almost in every rental house and VP's are so rare ??
