Novoflex Automatic Bellows (BAL-FUG) and Automatic Reversing Ring (FUG-RETRO) for Fujifilm GFX


Novoflex recently added an Automatic Bellows (BAL-FUG), as well as an Automatic Reversing Ring (FUG-RETRO) for Fujifilm GFX to their program. Both, the Auto Bellows and the Auto Reversing Ring allow for full electronic passthrough, meaning the camera and lenses are still able to “talk” to each other as if the lens would be connected directly to the camera. Above you can see images of both products.

The Auto Bellows is quite intereting in combination with the GF120mmF4 R LM OIS WR Macro lens. This lens offers a magnification factor of 1:2 when used directly on the camera. Putting the new Auto Bellows inbetween, at full bellows extension you’ll reach a whopping 3x life size magnification at 13cm working distance (front lens element – subject).

Here are some other examples:
Fujifilm GF 50mm f/3.5R LM WR
achievable magnifcation factors: 1.5 – 4.4:1
Fujifilm GF 32-64mm f/4.0 R LM WR
achievable magnifcation factors: 1.2 – 4:1 (in reverse position on the bellows)
Fujifilm GF 45-100mm f/4.0 R LM OIS WR
achievable magnifcation factors: 0.59 – 3.6:1

The Auto Reversing Ring FUG-RETRO has a 77mm filter thread by default and is best used with zoom lenses e.g. Example: with a Fujifilm GF 45-100mm f/4.0 R LM OIS WR in reverse position directly on the camera, a magnification factor of 1.1:1 at 100mm focal length up to 1.9:1 at 45mm focal length can be achieved. Lenses having filter threads other than 77mm can be used with stepping rings. 

As is usual with NOVOFLEX-parts, the Auto Reversing can be attached to the other universal bellows BALPRO T/S with Tilt/Shift movements, as well as the CASTBAL-PRO Bellows attachment to form full-fledged Auto Bellows again.
