I recently decided that the lens in the middle, a Nikon 24-70 f2.8 while really useful with its fantastic quality and versatility is a little big for carrying around on the Nikon D850. For this reason I have for some time used the wonderful little Voigtlander 40mm f2 lens sitting next to it. As it is manual focus, it does have limitations. So for some reason, I found myself looking for something that autofocuses and smaller than the big zoom, but not a lens that would be too close to the 40mm (which I love) and I found that I could buy secondhand for not a huge amount of money, this little 28mm f1.8G lens, so before I knew it I had a courier delivering a package to my door!
My initial impression is that I have a really nice little lens, that autofocuses for my Nikon DSLR. So now, I just have got to go out and use it!
