Lenses / Re: Canon EF 50 F1.2L And EF 35 F1.4L Sharpest Settings
« on: September 15, 2012, 01:59:51 AM »
At 1.2 the depth of field on the 50mm L at close distances is about 4 millimeters. If you or the subject moves the slightest bit, it will not be in focus where you intended.

I usually compensate by shooting at F2 or 2.8 and find it very sharp at those f stops.

Ai Servo on the 1d x takes care of that.

Will the 5d miii do the same in Ai servo?

For a portrait with small movement I say they're very similar yes. If you work with the 85 L the difference in response is much better on the 1d x. But with the 1d will also track the eyeball of å running 3 year old at f1.2.

The 50L has focus shift - as you stop down from wide open, if back focuses, but at some point (which is dependent on subject distance) the thicker DoF overcomes the back focus.  So, if plotting the sharpness of the 50/1.2L based on autofocus (assuming it's AFMA'd normally, i.e. at f/1.2), I'd expect it to be sharp at f/1.2, then get progressively softer as you stop down until somewhere in the f/2.2-f/3.5 range, then get progressively sharper again, peaking at f/4 or f/5.6 then dropping again after f/11 when diffraction sets in.

What the heck are you doing lurking on these forums Neuro... you should be teaching a class on optics somewhere ...

It's just that it isn't sharper at 1,2 than 1,8 af'd. I do not notice the shift when stopping to 2,2, but I see that it is softer. But you're right that 5 is sharpest and it completely craps out on the smaller from 8 to 16.

50 L is sharper at 1,8 than 2,2 and the sharpest is f5.

35 L is sharpest at 2,5 (a bit surprising perhaps) and has a pretty even curve all the way.

24 L II is sharpest at 3,5 with more variation.

One should not expect 'mind-blowing' image quality from 1DX. It's an amazing body with an ordinary sensor.
Not that I resent mine but IQ is just not one of its strengths... For everything else, it's fantastic!
I agree. I'm happy but not blown away. Specially when u can get 4 extra MP on a 5D III for $3K less and the same sensor.

I totally disagree. I like the 1d X files much better than the 5d3. It has better DR, better sharpness, better low iso etc.

With very underexposed images like the one in the OP, it will show more noise. Try shooting it over and pull it down instead.

I haven't tried the much acclaimed 1ds3, but the 1d X kicks all other Canon bodies butt....

Lenses / Re: Where is Canon
« on: September 12, 2012, 08:42:45 AM »
I don't think Canon will release anything big here, they will showcase what they released three years ago, and is finally shipping ::)

The M-system will be a huge part of their stand, maybe a lens or two for that system. Maybe a firmware for either of the "new" dslrs.

What I would like to see is a big surprise announcement of the 35 L II now that the 24-70 is shipping. Maybe the new smaller flash. But nothing new body-wise I think. Top's a 70d.

I think they released quite a bit earlier this year so it's not like they haven't done anything for 3 years....

At what aperture settings is the 50L sharpest?
Thanks.

I ran a test through FoCal software, aperture sharpness test, and it shows the following:

50 L: Way sharper at 1,8 than 1,2 (obviously) but it is also quite a bit sharper at 1,8 than at 2,2. The very sharpest aperture is f5.

(Have no idea if this goes for every copy on every body, but this is a 2012 50 L on a 1d X)

It has the "dreaded shiftfocus", but I never worry about it, even up close, properly calibrated I don't notice shift. What a lens this is though, if you shoot test charts you might feel you overpaid, use it like a workhorse in all weather and shoot wide open and 1,8 and the 50 L will make you VERY happy....

epic fail! No lens mount, no zoom = no go.
like Sigma DP1, DP2, Leica X-1 ... dead in the water. 

I will never buy a one-focal-length camera.

This is just awesome, I applaud you sony.

+1 Absolutely. SOny might have some odd "standards" but they showed a long time ago that they are SERIOUS about digital photography, and back in the day I had ALL the dsc-p# cameras from Sony, (P10 my absolute favorite) Sync flash at 1/1000s and of the very best looking cameras around. Plus they were about 50 million times faster than the Ixus's.

Sony, you might not be best at everything, but you have the biggest balls and push everyone  else and always go where no concervative Canon or Nikon man will go. Awesome!!! I've been waiting for FF (digital) compact since, hm, ever?

Wow!  Is there any benefit to buying primes in this range?  Aside from the larger aperture for more light when you need it?
Larger aperture and lighter weight are very important benefits.  So there will always be a benefit to buying primes.  Also:  smaller size & more discrete appearance & less distortion for architectural subjects.  And finally, some photographers sometimes prefer the benefit of not being able to zoom; a prime lens has a single way of seeing and that can be a creative benefit, depending on the situation and the photographer's mindset.

Eh, and DOF... no way one can compare 2,8 to 1,4 at 24mm..or 35, 50 and almost 85..

Worse distortion at 24? :o
Ok, barrel distortion increased from 2.15% to 2.45%.  The 0.3% increase in distortion isn't going to affect my work too badly.  :)

Yeah, the difference isn't much, but the old one wasn't very good in this respect, so worse is quite bad distortion.

Worse distortion at 24? :o

The new Hood design makes it non-working at 70mm, bumps go straight to the barrel when extended.

Strange to me...

Equally strange is that it outresolves the ts24, that makes no sense in a great way!!

I'm very happy for those needing a 24-70 it's by far the best standard zoom ever. For me it must have been made differently to appeal..

Sony must done something right to already have people comparing it directly to the 5d3 ::)

This is a compact camera which the 5d isn't. Never(!) underestimate people's will and funds to get a smaller sized camera. After 15 years of selling this stuff I can safely say that for 90% of people getting a camera size is HUGE reason (no pun intended). And people have been paying insane amount of money to get smaller products since ever.

If this will be a huge seller, I don't think, but for Sony to be the first and for us to see the tech is here is WAY more significant.
