Canon 200mm f2.8 L (Original and Mark II)

Ladies and gentlemen, it’s time to raise our hats to a forgotten lens, launched in 1991 and discontinued without remorse in 2013. The original 200mm f2.8 L had a built-in hood and sluggish autofocus; the Mark II that arrived in 1996 was optically identical but quicker, and came with a bigger, detachable hood. It’s the …

Teleconverters v Pixels

A key advantage of smaller sensors like APS-C and Micro FourThirds is that of reach – specifically being able to work at long distances with small lenses. Sports photographers working in large arenas may favour APS-C over 35mm sensors for exactly this reason. Of course, larger sensors offer better low-light performance – specifically lower noise. …

In Praise of the Sigma 14-24mm f2.8 DG Art

Pilgrims of ultrawide excellence down the decades have been conjoined to a certain path. In the 1900s, they sought, coveted or made sacrifices for hallowed primes like the Zeiss 15mm and 21mm Distagons. Some prematurely foreswore mirrors to gain access to Contax Biogons, the shady temptations of Leica and Voigtlander rangefinder glass, and the peerless …

The Stats That Matter

In a recent post I talked about the minor difficulty of making a meaningful comparison between different cameras’ ability to acquire and track focus. This brought to mind a more general problem about hardware comparisons and the mismatch between what photographers need to know, and what metrics they end up discussing. Nerdy photographers (rather than …

Good in Low Light?

A standardised comparison of extreme autofocus capability Many photographic assignments demand effective operation in near-dark conditions. Sometimes it’s in the brief; at others the need arises unexpectedly: nature abhors a vacuum as surely as life hates an exact schedule. Suddenly the photographer finds themselves at the limit of their equipment’s capability: maximum aperture, uncomfortably high …

On Equivalence

Until you know for sure, it’s confusing to know who to believe. Is a 50mm f1.4 lens equivalent to a 75mm f1.8 on APS-C? Are Micro FourThirds sensors two stops noisier than full frame sensors? Can you get the ‘medium format look’ on APS-C by using a two stop faster lens? If you want to …

GFX Quick Test: Tamron SP VC vs Sigma DG Art

Tamron SP 35mm VC f1.8 v Sigma 35mm f1.4 Art DG HSM At maximum aperture, and a focal distance of 10m, the Sigma has distinctly sharper corners, with resolution dropping off rapidly in Zone D, but substantially more vignette. The Tamron has a more gradually tapering performance both in terms of vignette and resolution, but …
