Fujifilm recently launched a handy online tool for people ready to shop for Fujinon lenses. The site is called fujifilmxmount. You can test the whole range of lenses and see how different lenses and aperture values affect the image. Here is how it works:
1. Choose a lens
2. Choose aperture value (and zoom if available)
3. Click the “Take Photo” button

This is a nice tool that Fuji made. I like how they approached it.
Good job Fuji. Marketing hard at work. Awesome way to learn how your customers are using your product.
Very nice. See? thats one of the small reasons why I chose FUJI 🙂
Huh, didn’t expect this. Focusing inconsistent?
Cool little tool. Like it.
I like this too. But I don’t trust these results blindly. I compared the XC50-230 to the XF50-140 at f5.6 and 50mm and I was shocked to see that the cheap XC lens seems to be sharper than the new XF lens. Probably that’s the photographer fault. Can’t see why this would be the case.
Hmm. One lense is 50-140 at 2.8 with weather sealing. And compression at .12 vice .2. And 23 lenses on the 50-140 compared to only 13 on the 50-230. The XF has better build quality. A lot better build quality. And it focuses a whole lot faster. Considerably faster. Unless the condition is perfect, the 50-230 stays at home. Doesn’t get much use.
While the exemple below was not so clear, here we are definitely dealing with a big difference in focus. The 50-140 seem to be front focused by as much as half a meter! No wounder the golden crown being outside the DOF looks unsharp!
Looking at what is actually sharp on the railing the 50-140 seem be a very sharp lens. It is however no good publicity for Fujifilm when their own exemples show how inconsistent AF-S is on their lenses at close distance.
I think it is very possible the photographer didn’t use the optimal AF settings, hence the inconsistent AF. Different light can also affect AF. Contrasty light is more helpful for the AF than flat light
Can you adjust lens + or- on fuji x camera
like Nikon DSLR
Cool tool. Has been around for a while though.
I think it was a waste of time with light conditions so different in each photo
Interesting find. The golden crown is obviously the focal point of the photographs. But in these exemples the 10-24 may be a tiny bit back focused while the 23 is a tiny bit front focused.
It should however be noted that light is more contrasty in the 10-24 photo with the 23 taken in more flat sunlight. At a quick glance the 10-24 may therefore appear be sharper. However if one look more closely it is the 23 that resolves more detail and is the sharper lens, as expected, though only by a tiny margin.
Even more striking is the difference in Depth Of Field. But can all of it be explained by a possible small difference in focal point? I would rather think this is a prime exemple of how different DOF can be between two lenses with same focal length at same aperture. If anything we would expect a 24mm lens have thinner DOF than a 23mm lens, right? So don’t trust those DOF tables and calculation programs too much. Different lens constructions behave differently also when it comes to DOF.
Cool concept, poor implementation.
It’s a platitude that applies across the X board.
It seems this online tool could be more useful for XC lens users thinking about switching to XF lenses, or those who shoot in Auto Mode and JPEG mode only. Because it gives you the general idea and I salute this initiative, but you can’t rely on it’s precision.
Indeed. Wish it was more accurate.
It should not be needed on mirrorless cameras as focus is done straight on the sensor. DSLRs are different as AF metering is done on the light reaching the surface of the mirror and then transferred to the lens.
Metering can still be wrong on mirrorless cameras for a number of reasons depending on how they are set-up.
For exemple if the camera is set at multi then the camera will choose the most contrasty area for focus. As long as the wanted, central area is contrasty that may pose no problem. But if light changes and gets flatter the camera may search for something more contrasty to focus on.
There is also the possibility to manually choose a specific area for focus. But even then error can occur as the choice of the size of the focus point can influence how well it works. Again especially if the choosen area is not contrasty enough because of flat light.
Except stating AF-S was used there are no more details about the exact AF-settings. Therefore I find it likely the bad focus in some photos is a result of user error rather than the lenses being bad at focusing.
