In that scenario and when even just moderately moving subjects (someone shifting rather than walking) speed and accuracy go to the Fuji 16, Sigma 18-35, Fuji 35 in that order with the gap between the the Sigma and the Fuji 35 being larger than the Fuji 16 and the Sigma which are almost identical.įor photos utilizing 3x3 zone focusing and CAF with the subject being my two year old running towards me, things get a little more interesting. I will follow up when I get my XT4 in my hands in a couple hours but until then, here are my feelings with it on the XH1 comparing the zoom set to its prime counter part, or as close as possible (18 vs 16).įor photos utilizing single point all three lenses are just fine for mostly static subjects. I shoot things and people, not brick walls. Reason being, that's not how I use these lenses for 90% of my shooting. I'm only testing in this manner for the same reason I didn't test shots stepped down further than f2.8. I have loved my Fuji "mighty 16" but unlike the 35mm, I'm now considering parting with it as I don't require the extra FOV and the Sigma is so close.īefore anyone has to point it out, YES, I'm really only measuring center of the frame sharpness and not out to the corners. Light intake seems to give the Sigma a light advantage at 1.8 as well. I'd say the same for stopped down to 2.8. Even up against the excellently sharp Fuji 16mm 1.4 the Sigma is darn close if not equal at wide open at 1.8. At 18mm things become a bit of a different story. No shock since the primes should have the edge in all respects. The Sigma handles the job but both light intake and sharpness are superior to the Fuji 35mm 1.4. Comparing it to the primes, I'm not in any rush to sell my 35mm after this test. I don't have the Fuji 16-55 2.8 to test it against but I'd venture a guess that even at its softest 35mm end, stopped down to 2.8 it easily goes toe to toe with the more expensive Fuji. I will say that even at its softest end this lens is no slouch. 18mm looks great and only slightly improves by 23mm while holding that sharpness all the way up to 30mm before falling off a bit at 35mm. The soft end of this lens is certainly at the 35mm side. That said, the Sigma accepts the disadvantage and takes it in stride. Nor is comparing a lens wide open to one even slightly stopped down. All photos are raw images imported into lightroom with no settings changed, however with lens correction profiles left on.Ĭomparing a zoom to a prime is usually never a fair fight.

ISO and shutter were static for the shots to compare light intake.įuji 16mm 1.4 18mm 16mm 1.4 35mm 35mm 1.4 35mm 35mm 1.4 fairy certain I have those labeled correctly but there should be exif attached. Camera sitting on the table, stationary and supported so no hand held shots or changing subject matter. Most zooms offer their lowest image quality at the extreme ends of the zoom so rather than weigh results in a best case scenario, I like to measure them at their "worst". The 16mm 1.4 and the 35mm 1.4 are two of the most highly praised lenses for the Fuji X system. Lets start with the thing most important to most people on here: This is a revolutionary lens that overturns preconceptions while expanding the range of photographic expression.Had a quick minute to jump in front of the computer so here is my quick and dirty one week review of the 18-35. These outstanding performance characteristics are especially apparent in an APS-C format camera, since it has a slightly greater depth of focus than a full-frame camera. Taking on the challenge of creating the world’s first wide-aperture lens to offer an aperture of F1.8 throughout the zoom range, SIGMA has succeeded in creating a zoom lens that offers the same high optical performance of a fixed focal length lens. To solve this decades-long dilemma, SIGMA proudly introduces the 18-35mm F1.8 DC HSM next-generation large-aperture APS-C format standard zoom lens for digital SLR cameras. On the other hand, photographers often need to change the angle of view to properly capture the scene that presents itself. The definitive large-aperture APS-C format standard zoom lens.Ī large-aperture fixed focal length lens is great for achieving expressive bokeh effects and enjoying ultra-high optical performance. Image quality until now found only in a fixed focal length lens.
