24mm: Focal Length Series

So this is the challenge I have given myself: to head out on a series of Photomissions where I am only allowed to use one focal length per session. I will walk the same route each time; between Waterloo Station and Oxford Circus Underground, and shoot using only one prime lens along the route to see what I can catch, and report back the experience and challenges of shooting with that particular focal length. I'm hoping to cover 24mm, 35mm, 50mm, and 85mm.

This week it's the

24mm f2.8 prime.

NOTE: I am shooting on a full frame camera. If you're shooting on a cropped sensor camera (APS-C sensor) then these comments will apply more to a 15mm prime.

24mm was always going to be the difficult one. Usually when you shoot with this width you have a strong idea of the vista you want to capture, so it's not really suited to run-and-gun street photography. 

That said I did learn some things.

I set off from Waterloo about 7pm again to try and catch some 'golden hour' light. The moment I stepped out of the station I started shooting buildings because of the extra width. The problem I experieced immediately was the distortion I got with the lens. I had to be very careful about framing because, obviously, with a lens this wide I was getting the most distortion closest to the edges of my frame (barrel distortion) so it meant I was going to have to frame my subjects closer to the clean center and ignore the rule of thirds for the day. 

I haven't corrected the distortion in the images below so you can a feel for what I'm talking about.

You do get super wide prime lens which correct for this distortion, like the Canon 14mm rectilinear, but they are very expensive. You can also correct in post, but I find that the more you pull the image around, the more detail you lose.

After sticking to shooting buildings and wide scenes I decided to mix it up a bit so at one point I set myself the challenge of shooting a person with this focal length. To be surreptitious about it I found myself having to shoot from the hip. I almost bumped into the subject to get close enough without simply walking up and sticking the camera right in his face. You'll see below that he was busy dancing so didn't really notice me, but I was less than two paces away from him when I took the shot, so this obviously isn't a great lens for people unless you are looking for something more stylised and you are able to get right in your subjects face. Don't forget they will distort like crazy too so watch the shape, although you can get some pretty cool effects shooting portraits at this focal length, like this one  I shot a while ago.

The 24mm f2.8 I was using is another of the 'cheap plastic' primes from Canon. It performed ok. I'm not sure if I'm being harsh on it because I was grumpy about being stuck with such a wide focal length, but I found there wasn't as much latitude in the light and shade during the edit, and I really had to work at the sharpness of some of the images. It's still worth it as an inexpensive lens, but if you are a fellow pixel-peeper there are annoying little traits that may bug you.

I used to shoot a lot more landscapes than I do currently and I felt myself out-of-practice with this width. Nowadays I shoot mostly in the high rise confines of a city, or up close and personal with portraits and products. My 24mm doesn't come out of the bag much, but this little exercise made me want to get out into open space again and rekindle an old love for wide angle photography. 

Here are some of the shots:
