Fuji releases new 250mm f/4 lens, 1.4x teleconverter and two macro tubes for GFX medium format

It’s Fujifilm’s turn to make their new announcements this week, and they’ve got some that GFX medium format shooters are going to enjoy. First up, there’s the new Fujifilm GF 250mm F4 R LM OIS WR lens. It has a field of view equivalent to just under a 200mm lens on a 35mm body. So suitable for both longer distance outdoor portraits, as well as shooting closer wildlife.

But to help with the wildlife side of things, there’s also the new GF 1.4X TC WR teleconverter. Priced at an eye watering $849, it’s not exactly cheap, but if you shoot medium format digital, the word “cheap” probably isn’t in your vocabulary. Fuji haven’t forgotten macro shooters in the new announcement, though, offering both new 18mm and 45mm extension tubes.

Teleconverters are these great nifty little devices that actually add range to your lenses at the expense of losing some light. Depending on how big of a zoom factor you go for, you losie more light as well as focus speed and overall sharpness – a little more on that later. What does that mean in terms of actual numbers?
