p.1 #1 · New Canon wide primes


Maybe overshadowed a bit by the Nikon release and the 24-70 II there are two new slow wide primes from Canon.
A 24 and 28 f/2.8 with IS. While the predecessors were nothing to write home about I thought the inclusion of aspherics in such slow lenses is quite an interesting development. I obviously have no clue at how these will actually perform and if the stabilization is really the culprit for that effort.
But maybe those are the lenses quite a few have been waiting for. A lens for stopped down landscapes sharp into the very corners.
In any case you now have quite a list of lenses to consider if you want to get a 24mm lens for Canon with warranty.

What I can think of right now:
Zeiss:
25/2
25/2.8
Canon:
24/1.4
24/3.5 TS-E
24/2.8 IS
Samyang:
24/1.4

and then there are the more alternative lenses...

The MTF of the new Canon primes is stellar. Of course, the MTF of the new 24-70 is actually even better (and better than the 24L II).

Glad to see Canon release an updated 28mm prime. It's shame it's not f/1.8 (or even f/2) like the EF 28/1.8. Maybe they'll around to coming out with a 28/1.4 That would certainly make me rethink my camera choices.

I thought about adding it but decided to put it into the more alternative bracket. How well does stopping down actually work with the G adapter?

p.1 #6 · New Canon wide primes


I'm excited about the 24mm with IS. Sounds pretty cool to me. I've always liked wide primes, they are my most favorite lenses to shoot with. I just hope it's not too much more than the current 24mm 2.8 (which I believe is a little under $400 new), I can't really justify spending $600+ on a lens like that seeing as I already have a 24-70 2.8... But, this one has IS

Where can we find this MTF?

MTFs from Canon should be taken with a grain of salt, because they're theoretical, so they aren't directly comparable to those from Zeiss, FWIW.

It works fine except that it doesn't stop down to more than about f5.6, as relative to wide open by looking at shutter speed.
I am sure I could make a small change to the adapter so the aperture lever could travel a little longer to stop down further.
But since I have the ze 21 which I use for landscape instead, I usually shoot this lens wide open or stopped down a little.Also, the lens becomes sharp into the corners by 5.6 so It is still good for landscape if I need it. I agree it is pretty alternative.

It's $850 MSRP... sorry.

Takk.

Unfortunately it doesn't say what the curves represent.

from: http://www.luminous-landscape.com/tutorials/understanding-series/understanding-mtf.shtml


The thick lines are measurements taken at 10 LP/mm (low spatial frequency, or low resolution) and the thin lines are at 30 LP/mm, at higher frequency / higher resolution.

The black lines are measurements taken with the lens wide open, and the blue lines are with the lens at f/8.

The solid lines are meridonial while the dotted lines represent sagittal measurements.

Bare hyggelig!

What we know about the charts is that they are theoretical as Douglas said, and they ignore diffraction, and MichaD mentioned the line frequencies and apertures.

Here is what Canon say, in "Optical terminology and MTF characteristics"

http://www.canon.co.uk/For_Work/professional_photography/ef_lens_work_III.aspx

We don't even know if their model uses monochromatic or white light.

Takk igjen.

It is indeed clear that Canon ignores diffraction; some curves are much higher than physically possible. Hence I propose to ignore the Canon MTF.

So you don't believe the 180 Macro with 2x TC at f/16 has about 99% modulation in the center and 30 cycles/mm?

It will be interesting to see how the 28 performs and if it knocks the Alts (Leica R 28/2.8, Contax 28/2.8 MM, possibly others) of their perch.

I'm interested in the 28mm if it is good.

It might replace my 35mm f2 as a walk around lens on my 5D Mk II.

I'm happy about IS.
Not so happy about the speed.

The price seems up there too.

Those two lenses go up there with the 16-35 VR as far as odd releases go.

/shrug.

The new 24-70 looks nice. However, I'm completely content with my lenses. The only thing I'll be adding is an MPE 65 again.

+1 yes a grain of salt because they are theoretical. But comparing them against other Canon lenses gives you a hint
