Nikkor 24 1.4 vs 28 1.4

Merkin

Have you had a look at DOF tables to see how much more isolating a 1.4 aperture is compared to 2.8 at the distances you normally shoot at with a 28mm or 24mm lens? These lenses have so much DOF that it might not make much of a difference even at 1.4 and you can save a load of money to boot.

the difference is considerable, but I don't think it is 1500 to 2000 dollars worth of considerable, sadly.

One chart I looked at said a 28/1.4 on a D700 @ 10 feet has a DOF of 3.4 feet which is considerably smaller than the same lens stopped down to 2.8 with a DOF of 7.36 feet @ 10 feet. For some reason I don't consider a DOF of 3.4 feet close up to be particularly effective for isolating things. Yes, for the very few times it might come in handy it is not worth the extra money for me either.

I was taking a look at the 24mm numbers- at 1.4, at 10 feet, total depth of field of 4.69 feet, and at 2.8, at 10 feet, the total dof was 11.1 feet. The numbers that were particularly noticeable to me were the 20 feet numbers- at 1.4, total dof is 22.4 feet, and at 2.8, 179 feet. You certainly can't isolate anything with either of those depths of field, but a 24mm at 1.4 has an equivalent dof of a 50mm with an aperture between f5.6 and f8, which would be really nice for urban landscape/architecture type shots. It still isn't worth the extra money though.
 
Well, I suffered a severe bout of GAS and picked up a 24mm f1.4 earlier this evening. Damn the thing is sharp at f1.4, and yes it can throw the background out of focus quite easily, but the bokeh seems to be a bit funky in certain situations.

Here's some gear shots!





And a sample photo taken at f1.4 and ISO 1600 just because I could 😀

I think the bokeh is actually pretty decent, certainly so for a high-speed strong wideangle. The Canon and Leica 24s are certainly in the same ballpark.

If anyone is interested I've uploaded about 20 shots taken with this lens to flickr (link). Most of the shots were taken at f/1.4 where this lens deserves to be shot.
