Nikon's 14-30mm was one of the lenses that made me most excited about the Z system. A compact, weather-sealed UWA zoom lens that could take screw-in filters, but was no bigger than my previous UWA zoom lens (a Panasonic Leica 8-16mm f/2.8-4 for Micro 4/3). However, when Gordon Lang published the original review of the 14-30mm, I was quite disappointed in the lens' performance, so much so that I was planning on holding on to my Tamron 17-35mm f/2.8-4 Di OSD. However, Gordon has since received a second copy of the lens and updated the review, which to my eyes puts the lens on-par with the Tamron (which is very good IMO). I received my copy of the lens today, and did what everybody does when they receive a new lens: shoot brick walls! Yes, while this isn't what I'll be shooting with this lens on a regular basis, it gives me a consistent subject to shoot with fine detail, and compare against other lenses. To provide a bit of context around my test and settings used: All images are JPEG (to apply the built-in Nikon lens profiles for correction, since I don't have LR). AF-S, VR off, Electronic Shutter was used, 3s delay in shutter. Aperture priority, ISO 100, no exposure compensation Shot on a carbon fiber tripod (32mm leg diameter) with an RRS BH-40 ball head I've provided all of the images I shot for download if you're interested in taking a look for yourself (download all the images here). However my takeaways are this: My copy of the lens appears to be pretty well centered (phew!) The lens is already pretty dang sharp wide open, but the corners do sharpen up a bit at f/8 The 24-70 is wider than the 14-30 at the shared focal lengths (24mm and 30mm) The 14-30 is a hair sharper than my Tamron 17-35 In summary, I am very pleased with this lens. The lens is sufficiently sharp for my needs, and I appreciate the smaller size for traveling.
