What does 35mm crop mode do on a native GFX lens? Say you had the 80mm F/1.7 which works out to be a 63mm F/1.3 in full frame terms. Does that 35mm crop mode turn the lens into a true 80mm F/1.7?
Basically, yes. If you are trying to find the 35mm equivalent focal length of the FUJIFILM 80mm f/1.7 R WR G-Mount Lens when using the 35mm Format Mode setting in the FUJIFILM GFX50S II Medium Format Digital Camera, it would be the equivalent of an *𝟴𝟬𝗺𝗺 𝗳/𝟭.𝟳 𝗹𝗲𝗻𝘀* used on a 35mm camera. So the simple answer is 80mm. As you are already using a 35mm equivalent conversion to see the 80mm lens using the full sensor (which would be the 63mm equivalent used on a 35mm sensor due to the 1.27x crop factor), once you crop the sensor down to a 35mm sensor size, you no longer need a crop factor to figure out the 35mm equivalent; it cancels itself out. To find a G-mount lens' 35mm full-frame equivalent focal length when using the *𝗙𝗨𝗟𝗟 𝗦𝗘𝗡𝗦𝗢𝗥,* you divide the lens focal length by a crop factor of 1.27. As such, an 80mm G-mount lens would be the 35mm equivalent of a 63mm lens as 80 ÷ 1.27 = 62.9. But when you use the *[𝟯𝟱𝗺𝗺 𝗙𝗼𝗿𝗺𝗮𝘁 𝗠𝗼𝗱𝗲]* in the camera's Shooting Menu, you are cropping the full-frame G-mount sensor to the size of a 35mm sensor. Since you are only _seeing_ the 35mm sensor size, you don't need the crop factor to _calculate_ the 35mm sensor size. It cancels out. As such, the 35mm full-frame equivalent of an 80mm G-mount lens used with the camera's 35mm Format Mode is 80mm; just use the lens' focal length instead of calculating and canceling the calculation. It's easier.
This lens , the IBIS & pricing, combined with the coming GF 20-35. (16-28) put this at the top of my list for this switch to mainly mirrorless So many advantages now make it hard to resist, I remember well my GA645 from the film era and see it’s digital cousin in this incarnation .
Thank you so much. This Fuji camera is cool at real. I happened to see some shots of Paris city with its large sensor predecessor, with some manual focus lenses - that's stunning incredible!
Update? What update? Nothing really improved other than the price. Same sensor, no hybrid AF, no DR expansion, no speed, EVF or image quality improvements... on top of it they took the vertical grip option and fit all in that dumb 100s body. Afters years, is this a Mark 2 version? Really? When all other camera manufacturers, SONY, Nikon... They offer everything and better in a more compact and affordable package. That's a marketing blunder. What are they thinking, for heaven's sake?
They are thinking that FF is last yr -so they passed go and went straight to MF 0 no biggy - bigger sensor is better than FF even if smaller sensor has more pxls.
