fuji x-h2/x-t5 crop mode

Hello,

I'm considering to switch to fuji and wondering if using a lenses in crop mode does the result will be good enough (i guess 20mp from a 2x crop 40mp).

Goal is to travel light with only a prime lenses. Ex: 16mm 2.8.

Suggestions / advise ?

Due to the 40mp sensor of the XT5 I have been using crop modes a lot for street photography, very akin to how people you the Leica Q2.

The quality does downgrade considerably if it was to be used for Wildlife or anything where fine detail is important. But for street where I usually add a little grain It works great. Its defiantly something a lot more possible now then with the 26mp sensor.

Attached an example with the Viltrox 13mm (My Fav lens atm) using 2x crop.

Here's how it works;

4:3 ratio is a 1.125x crop of Horizontal FOV, hfov, so horizontally you can see the effect, you may want to crop it to 3:2 in post but the result in-camera is that a 16mm is now a 18mm (plus 1.5* crop)

5:4 ratio is a 1.2x crop, as above, so 16x1.2 ie 19.2mm

1:1 ratio is a 1.5x crop, as above, 16x 1.5 ie 24mm

〈4:3〉 6864 x 5152 〈3:2〉 7728 x 5152 〈16:9〉 7728 x 4344 〈1:1〉 5152 x 5152 〈5:4〉 6432x5152

In all results if you shoot raw, the full 7728x5152 raw can be recovered, only the jpg is cropped!

Now you also have, sports finder mode, 1.29x crop, so the 16 becomes 21mm, but in this mode you get full view but a white border of the crop is presented. The raw and jpg are both cropped by 1.29, ie you now have 24mp image in 3:2 and raw

You also have 2 further options, 1.4x, this crops the image by 1.4x and also repositions the viewfinder so it fills the frame, completely. Now, we also have the smaller raw and jpg, ie 20.3mp and the 16mm would now be a 22.5(+1.5x crop)

as above the 2x reduces the size to 10mp and the 16mm becomes a 32mm(+1.5x crop) and the raw and jpg will also be 10mp

So, yes, you can make the 16mm work all the way 24mm to 40mm FF equivalent, without much effort and even to 50mm FF if that's what you need.

You can also just use above ratio's and converters to show the effect in-camera and then revert back to the full field of view for the shot.

Thank you this is a super-helpful post so I'm reviving this thread for now. I have ordered an X-T5 and was kind of dubious about 40mp, but I never did consider that it would make crops more useful. I'm actually kind of excited about this now.

So if I have this right the modes behave a little differently. I'll use a sample focal lengths as an example.

18mm lens (28mm FF equiv) prime lens becomes:
  23mm (35mm FF equiv), in sports finder mode = 24mp jpg + full res raw file
  25mm (38mm FF equiv), in 1.4x crop mode, 20mp jpg + 20mp raw
  36mm (54mm FF equiv), in 2x crop mode, 10mp jpg + 10mp raw

23mm = 30, 32, 46., but 32 and 46 are lossy.

I think this is another way of saying, Sports Finder mode draws a box around a 1.29 crop but you still have the full res raw. Tele-convert (crop) modes really crop the raw and jpg in camera.

Of course, you can always crop a full file later if you want. But these modes are useful if you want to "use" another focal length, and compose with it in the camera, without buying a new lens. So the increased resolution really helps.

So, If I have a 23mm lens, do I also need the 33mm lens if Sports Finder mode does a 1.4x crop? I'm considi=ering buying both, but not if I don't need to. I have the X-T5 and a 1.4 crop takes it down to 28mp - which is plenty for printing.

It’s actually a 20mp file. Still plenty for printing of course but just making you aware in case that 8mp makes a difference to you.

No, that's still plenty

Thanks

You're a little off on the conversions, but whether you "need" a 33mm lens depends. If you want to shoot a 33mm and get the full 40mp image, yes you need one.

Sports Finder vs Teleconverter are different modes that do slightly different things. So for a 23mm lens (I have one too), if I understand correctly:

23mm in Sports Finder (1.29x). You get a 30mm @24mp jpeg. You also get a 23mm 40mp raw file, per normal, as though you never used Sports Finder mode.

23mm Teleconverted at (1.4x). You get a 32mm @20mp raw + jpeg.
23mm Teleconverted at (2x). You get a 46mm @ 10mp raw + jpeg.

So a 23mm can be "used as" a FF equivalent 35, 50, or 70mm (roughly) "zoom lens" with these modes, with resulting loss of pixels for the TC modes. In either case you get a compositional aide.

Now, whether using a different focal length changes the physics of the images, I don't know. I'd leave that to smarter people than me.

If I had to guess, I would think that perspective does not change, because you're still standing in the same exact spot no matter which crop you use. But distortion is different between lenses. So if you try to use an ultra wide-angle lens cropped to a normal, the image would probably be different than if you used an entirely different lens.

Thanks Greg, I'll try the teleconverter option when I find it in the menu (I've seen it, but there's so many options, I keep losing stuff )

i still wish when one selects 4:3 on camera the RAW would also be cropped and not just the jpg.

Once this becomes a reality in all cameras (if it does), it will be "game changing" especially if you viewfinder shows the crop well and you have enough MPs to choose whatever you want to do (which, let's face it, will be the case since MPs just keep going up).

I previously thought so, but it looks like the only 20 MP mode available is the 1.4 crop mode ; can anyone confirm ? Kr, P.
