How sharp is the Fujifilm 23mm f2 lens?

I had read a lot of good things about Fuji's collections of lenses before I made the plunge and bought the X-T2. And I've got to admit I am very impressed by the 23mm f2.  It's small, light, tactile and fantastically sharp.  To be clear though, this is not a complete lens review, only a sharpness test at apertures from f2 to f16

All of the shots were below were taken the Fujinon 23mm f2 lens, with the x-t2 mounted on a tripod.  All I did was adjust the aperture and shutter speed to get an exposure.  The images shown are out of camera JPEG’s using the Classic Chrome film simulation.  No retouching or noise reduction has been applied.

It should be fairly obvious from the test shots above that the 23mm f2 is damn sharp between f2 and f3.2 the edges lack focus but from f4 on the entire frame is gorgeously sharp.  To be honest I could happily use the lens wide open at f2 If was intending to blur the background anyway.

You can download a zip file containing all these JPEG's at 100% size by downloading them here.  You can also see how the x-t2 noise fairs with my ISO test here or see how Fujifilm's different film simulations affect a photographs look here.  Want to see more Fuji blog posts?  Leave a comment below,

Sigma 18-35mm 1.8 DC USM Art Lens review: Sharp, sharp, sharp!

Following on from my initial thoughts of the Sigma 18-35mm 1.8 DC HSM Art lens, have my feelings changed about this lens?  Or has extended use the lens brought us closer together?

I decided to try out this lens during a recent holiday to the Greek island of Santorini.  I do not normally do travel photography and I can honestly say after my time in Santorini I have a greater appreciation of the travel photographers art - how they achieve anything worthwhile whilst working in such blistering heat is beyond me!  Anyway, moving on...

The image quality is fantastic

I normally shoot between f5.6 and f11 and the image quality is excellent within this range.  One thing that was particularly noticeable was the lack of flare on the lens in such harsh sunlight and chromatic aberrations were virtually nil.  All images looked fantastically sharp, even prior to RAW processing in Lightroom – I actually found myself questioning whether I had applied sharpening to the image already and had to double check.

18-35mm reach is fine (for me)

I had no issues shooting with what some would regard as a limited reach.  I prefer to shoot minimal style images so this suits me but I can certainly understand that most travel photographers would find this limiting.  That said, It really is worth considering exactly what type of images you are going to shot before opting for a lens such as this.

It's still too heavy

As a travel lens I think this lens is too heavy - I will stick to my primes from now onThe Sigma weighs in at 1.79lb on its own so add that to a camera, and even a light bag and it can be become a bit bothersome to lug around.  That by being said if you want to take quality images using an Nikon APS-C camera then the extra bit of weight is perhaps worth the bother.

Conclusion:  Is the worth buying?

There is no denying that the Sigma 18-35mm F1.8 DC HSM Lens  is a fantastic lens.  The sharpness you can achieve on a Nikon APS-C camera is fantastic.  As I stated earlier I usually shoot between f5.6-f11 but when I did shoot at f2.8 image quality appeared to be maintained.  Really, the only downside for me is the weight, it is really is noticeable, if you used to using prime lens.  That being said if you want sharp images this is the lens you need.
