I have 16mm, ultra wide converter than turns 16mm to 12mm and 18-55 kit lens.

Can you use the ultra wide converter on the 30mm? How about the 19mm?

  • 12mm -> ~18mm equivalency (16mm * 0.75)
  • 14.25mm -> ~22mm equivalency (19mm * 0.75)
  • 16mm -> ~24mm equivalency
  • 19mm -> ~28mm equivalency
  • 22.5mm -> ~35mm equivalency (30mm *0.75)
  • 30mm -> ~45mm equivalency

18mm, 24mm, 35mm, and 45mm, equivalency seems a better range than 18mm, 22mm, 24mm, and 28mm, equivalency.

Thank you


You cannot use the Sony UWA, bayonet-mounted and for the 16SEL2.8, on the Sigmas. But what you CAN do is use the excellent 45 gm. fish-eye or UW from Panasonic G. m43 camera lenses. It fits inside the Sigma 19's hood, 46mm filter threads! I use it often; mine is the fish-eye which works like a UW on the NEX. The quality is excellent.

Can you point us too or do you have any examples with this combination. Sigma 19mm and Panasonic wide and fisheye, ​Is this the lens your are referencing to,
