Hallo all,

Ever since I got my 16-35GM I found it sitting in my bag rather than on a camera. Whilst the picture quality is fantastic I thought it is taking too much space in my bag for me to take it with me everywhere I go. I normally shoot telephoto, including landscape photography, but occasionally I come across a scene which just begs for wide angle. That was the whole point of me buying into the 1635GM. But the size and weight of it is prohibitive long term, so I thought I would experiment and get the widely praised 20mmf1.8 as a potential replacement

Got it yesterday and took it for a bit of a benchmark test against the 1635GM.

I am happy to discover that to my eyes, it is not softer than the zoom, in fact I find it's corners sharper - even at f1.8!

This is by no means scientific test, but just a casual shoot.

16-35GM

20mm f1.8

As mentioned above I am surprised to see the prime corners much sharper than the GM, yet the center is a tie in my eyes (maybe even slightly sharper on the zoom):

center crop, prime on the left, zoom on the right

corner crop, prime on the left, zoom on the right

Another scene:

16-35GM, this time stepped down to f8

20mm f1.8, f8 as well

Surprisingly, the prime beats the zoom at f8 as well.

zoom on the left, prime on the right

again, zoom on the left, prime on the right.

Last, but not least, here is the comparison of their sunstars.

prime left, zoom on the right, both shot at f22

Please do not take this post as provocative. I merely want to share my experience and decision making process in order to optimise my lens portfolio.

I think I will be selling my GM zoom and keeping the prime. Versatility of the zoom turned out not to be an advantage with my shooting style, but the weight and space savings (never mind the cost) are significant.

Thanks

Dom
