I would enjoy seeing more of these kinds of comparisons.įor 2 different lenses, it will certainly not be a fair comparison of the lens since newer lens tech will have improvements, instead it would be a test of the sensor, as well as a test to see if the benefit of an optimized lens is worth while. No matter what, any test like this creates more questions and a lot of arm chair quarterbacking, which is fine, but everyone who says "you should have done this" is welcome to do their own tests too. But this also would have its own challenges. To do what you are suggesting I guess the best way would be to take 2 35mm's for example, and then an XT4/XT5, and compare both lenses on the older and then newer sensor side by side. I also wanted to see how much of an improvement the 40 megapixel sensor is practically speaking. This is why I figured it would be interesting to see how each lens performed on the older vs newer sensor. How do you create a fair comparison using two different lenses, which have completely different optical properties? If I used an older 35 vs a newer 35, and conclude that yes, the newer lens is better on the newer camera, the obvious problem is that people would say "of course it is." I thought about this, and to me there's no way to prove that the "optimized" lens is better in this situation, since the newer 35 would perform better even on the older camera. On many cameras, a higher res sensor will capture more detail, even on an older lens, since resolving capability of a lens varies throughout the frame (dropping as you get closer to the edges).Īs an extreme example, the Nikon AF-P 70-300 f/4.5-5.6 (full frame entry level lens), looks better on the Nikon D850 than it does on the D780, though it in no way means that the AF-P 70-300 is a good lens for the D850, as even though it looks better, it is acting as a massive OLPF for the D850 sensor. A comparison using the same body would make it easier to see how much of an improvement the "optimized" lenses offer, as well as spot contradictions, for example, will an "optimized" zoom lens at 35mm offer less fidelity than anon-optimized 35mm prime lens? Will the optimized zoom lens at any focal length out-resolve the non-optimized prime? For example in the video he kept using 2 different cameras, thus making the test a comparison of the X-T4 and the X-T5, when really the test that should have been done, was comparing an "optimized" lens, to one that was not "optimized" using the X-T5 for both lenses. Combined with the marked aperture control rings on many of Fujifilm’s X-system lenses, they give you full control of all exposure settings before you even turn the camera on-a boon to street shooters, photojournalists, and any photographer who likes to pre-set exposure to react swiftly to the scene.The video seems to miss some of what Fujifilm and others have talked about in regards to "optimized" lenses. Its most obvious features are the well-placed dials for shutter speed, ISO, and exposure compensation. Capture is pretty fast, too, with a burst speed of 8 frames per second for up to 83 JPEGs, 33 losslessly compressed Raw files, or 27 uncompressed Raw images.īut what truly boosted the X-Pro2 onto the winner’s podium was its brilliant body design. Factoring in its highly accurate color rendition, we rated overall image quality Excellent up to ISO 400. Resolution at ISO 100 was the highest we’ve seen from an APS-C-sized sensor, and the camera held noise to moderately low up to ISO 800. Of course, the X-Pro2, with its 24.3MP APS-C-format X-Trans CMOS III sensor, delivered terrific results in the Popular Photography Test Lab.
