Following on from yesterday’s Fujifilm X100F Overview, here is a walk and talk through sample images I shot recently. Please do not expect artistic merit here, however, most of the scenes were deliberately selected to show me something about how the X100F’s 23mm f2 Fujinon lens performs at different apertures and distances. Please note that I will be covering the image quality delivered by the 24MP X-Trans III sensor in separate pieces. Resolution of fine detail and textures compared to a Full Frame 24MP Bayer sensor is here.
Whereas most standardised ‘lab tests’ test a lens at a single focus distance, I feel that this isn’t very helpful. A lens can perform very differently on a 2m lab test than it does in the wild, shooting over much longer distances. Assuming you shoot real scenes with your future Fujifilm X100F (and not test charts in your own lab), knowing how your lens performs at different apertures and distances will help you get the best out of it. Most lenses do suffer reduced flatness of field at long distances (notably zooms), meaning to get the sharpest edges on the horizon, you may need to stop the aperture down more than you would for a flat subject at, say 10m. OK, waffling over and here we go….
Please note that all Fujifilm X100F files are 1500 pixels wide and that crops are at their native resolution. All files will be JPEGs straight out of camera at base ISO (200) unless stated otherwise.
Here is a Fujifilm X100F example at a distance where this lens is really starting to get into its stride. The hedge is actually very flat. f4 is two stops down, but this is a wide angle lens and you’d be forgiven for thinking it would not quite be on top form in the corner.
Now we’re going to move onto an equally fascinating subject that is a little further away again, perhaps something in the region of 3-4m. Here, we will compare wide open f2 with f2.8Fujifilm X100F examples. This is an extremely tough test for any lens. Brickwork is full of fine detail and the wire will show up any softness. First with the whole scenes:
Firstly, you can see vignetting is very well controlled through baked in profiles. Secondly you can see Chromatic Aberration (CA) in the top right, which lessens at f2.8. This scene would have generated CA in most lenses and so I’m not surprised to see it here. Now for the crops.
Now let’s look at a more likely ‘scene’. It isn’t interesting, but at least it is in B&W 😉 These areFujifilm X100F Acros JPEGs straight from camera.
More Acros here – SOOC . This scene should give you an idea of how the camera, lens and Acros renders tones. I’d be surprised if you have not already formed the same conclusion I have: the Fujifilm X100F rocks for B&W and the SOOC Acros JPEGs are either an excellent quick and dirty solution, of plenty good enough for the end result.
With some lenses, you might expect the left edge to have done a bit better than the top right hand corner, with focus on the hut. However, with this lens, the top right is remarkable and the left edge needed a bit more stopping down. This would be consistent with a bit of field curvature, which would be exacerbated by the point of focus falling on an object already closer to the camera than the edge. The same thing actually aids the top right, bottom right and bottom left.
Now for some typical urban medium distance shots from the Fujifilm X100F.
Now back to a few more distant scenes, this time wide open! You’re caught short of light, the shot is a good’un and f2 is your only option. How’s the Fujifilm X100F going to do?
Are you getting bored yet? If not, then I guess this is useful…. so carrying on:
… and finally, if you’re still alive, here is an ISO 12,800 colour file.
I hope this was useful. It may have bored me to tears, but a few hours around town and a few hours on the computer means that I feel I know this lens very well. It is fair to say that I am completely smitten with the Fujifilm X100F. I want to take photos with it and I don’t find myself in any way left down by the results when I finally look at them. This camera needs to go places with me.
P.S. I am not sponsored by Fujifilm, they have not provided me with the test camera and no inducements have been offered of any kind. It is possible to be independent and hugely impressed! As many of you know, I love the 35mm focal length (on full-frame) and B&W. This camera serves up two dollops of wonderfulness on both counts.
