It’s nice when you have several choices for a given lens, but it can be really hard to choose the right one.
For example, most wildlife and sports photographers start with a 70-300mm f/4-f/5.6 lens. But, Canon and Nikon each make several different varieties, and third-parties (including Sigma and Tamron) make their versions, too.
While nothing replaces hands-on experience, that would require me to buy/rent/borrow several different lenses and then spend about a full day shooting with them and analyzing the results. In just a few minutes, I can look through DxOMark’s sharpness measurements and at least narrow down the playing field.
First, I browsed DxOMark to identify all the lenses in the 70-300 range for the Nikon platform that they had tested. It’s also a good idea to search at Amazon and B&H to see what else might turn up:
After about 8 months of real-world use, we’re finally publishing a review of our favorite and most hated lens: the Mitakon 50mm f0.95.
It’s a manual focus, full-frame lens that ONLY fits Sony full-frame bodies. You could technically put it on a Sony APS-C body like an a6000, but then it becomes more of a portrait lens (75mm f/1.4 equivalent), and it loses much of its great qualities. Plus, at $900, it costs more than a used Sony a7, so you might as well upgrade the body first.
It can do this:
Check out that crazy background blur and vignetting! It looks like someone overdid it with Instagram filters, but it’s real, genuine, and fun.
But first, this lens has a HUGE flaw, and it’s the same flaw that many of the world’s most loved lenses have, including the world’s sharpest lens, the Zeiss Otus 85mm: It’s manual focus with a shallow depth-of-field.
DxOMark published their objective measurements of our favorite camera in the world, the Canon 5DS-R. As usual, the media has taken the (largely meaningless) “Overall Score” measurement and used that to rank the camera. Here’s a headline from a page I like, SonyAlphaRumors:
