Nikon Z 100-400 centre vs Nikon 80-400G & Sigma 150-600 C

This is the second post in a series of evaluations of the Nikkor Z 100-400. Please refer to the first post for details about the test equipment & methodology. In this post, I’m going to compare performance in the image centre between these three telephoto lenses at 400mm: Nikkor Z 100-400 (e.g. from Amazon). AF-S … Read more

Nikon Z 100-400 centre performance

Last week my Nikkor Z 100-400 arrived. I’m in principle upgrading from the AF-S 80-400G, which has been my all-time favourite lens (both sentimentally and in terms of the yielding the greatest proportion of my favourite photos).

iMac Pro first impressions

Lightroom “Classic” doesn’t play well with others

So far the new “Classic” Lightroom looks & feels mostly identical to the prior version(s), which isn’t really a compliment, but could be worse.  There’s no apparent performance improvements, that’s for sure, so as expected Adobe’s promises to suddenly learn how to write efficient & performant software, well… at least their marketing department gave it … Read more
