So You Want To Shoot With A Fast Lens….

Tutorials

Cabin fever is about ready to set in so I tried to do something constructive photographically to ease the pain. I wondered just how much leeway one might have when trying to focus with my Canon 50mm F/1.8 set wide open. Yes, I know quite boring right? Well I needed something to do as the snow came down yesterday. I know the depth of field is quite narrow at such wide open setting but I thought a photo might help….

So I present to you this totally unscientific tutorial using nothing but a clicker and my Canon 5D Mark II and my Nifty Fifty, Canon 50mm 1.8. Let me start with the exif data for this shot…

1. ISO 160

2.50mm

3. F/2.0

4. 1/60 sec.

I set the camera on my countertop approximately 18 inches away from the tv clicker (propped up with a salt shaker) I told you it was totally unscientific:) I’ve uploaded the shot at almost full resolution so if you click on it you’ll get a better idea of the cold hard truth.

_MG_9273I did my best to focus on the blue dvr button (you can see it if you enlarge the photo) and after measuring the distance from my focal point to a point of out of focusness (is that a word?) it was less than 1/2 an inch. Not a large margin of error even at f2.0.

So if you are thinking that a fast lens such as the 50mm 1.8 will solve all of your low-light problems, it will but it may also present you with a few focus issues (such as shallow depth of field). The learning curve is still there but once mastered, these lens produce some fantastic results. Hope this little tutorial helped.

  1. Not only will it produce some fantastic results, at ~$100, it’s a killer little lens. I put mine away, forget about it, then pull it back out and fall in love with it again. I love dropping to that 1.8. Yes, it’s not perfect, but for the price, and for what you get, it’s worth it to have it in the bag.

  2. I love my 50 1.8! I fall in love with it again every time I pull it out of the bag to play with. Admittedly it doesn’t end up on my camera often but when it does I am always reminded how amazing that super shallow dof can be…
