Canon may be expensive but...

[EYEONE]

WWOOOOOWWWWWWW!
Did you guys see the MTF chart on the Nikon???

Nikon without TC:

Nikon with TC

Borderline perfection!!


Here's the Canon to compare:

You can't compare Canon MTFs to Nikon MTFs. It's not a valid comparision.

you can not come with assumption like that with out explaining what you meant

we dont know if this is estimated MTF, Canon and Nikon has a predilection to exhibit estimated MTF results to impress

Yes I can.

Ok , tell me

Hey man, I really don't give a crap. I actually meant that I can come with an "assumption" if I want to.

The way I understand MTFs is that they are not comparable between brands because the the info is not gathered the same way. There are no standards.

If you want links, I have zero desire to find them for you. But I doubt you need them as you seem to be way-super-smart.

1. well... do i trust given information from nikon? not really. why? because of this: they claim this image is taken with nikon d5200, but take a look into metadata

sample image 3: http://chsvimg.nikon.com/lineup/dslr/d5200/img/sample01/img_03_l.jpg

update note: recently download the image to ensure the same image that i downloaded before. check metadata and it is now d5200, not d800e anymore, not sure if it is the same image since i do not remember, but it should be the same scene. ONE THING THAT I MIGHT HAVE A GUT TO SAY THAT "NIKON MARKETING TEAM IS ON CANONRUMORS CHANEL "

LOL

2. it is so bummer when comparing old design and old technology to new one. use your brain please

In Sweden the Nikon 600/4 is almost 5000USD cheaper than Canons 600mm
Why on earth do you think the street price will be higher on the Nikon 800mm than the Canons?

New design with new technology always much more expensive and this has been proven from time to time right I guess next Canon 800mm will be about the same price, depending US dollars... will probably not be cheaper than nikon though

#not impressed. :\

OK


Are you buying pro gears and traveling a lot I can recommend Profoto from Sweden, used them since first Pro1

Profoto is top-notch equipment but Its not what I'll be needing. Love the Modifiers for them.

4x PCB Einsteins are my current plan.

I don't know, if Canon can update the 17-40 f/4, and possibly add IS ... it would be wider on the wide end, longer on the long end, a fixed max aperture, and have IS. then they could definitely justify pricing it above this quirky Nikon UW zoom.

Right, my point is more than the cheapest wide-zoom available isnt going to go below $750. Some people, in the wake of the new 24-70 f/4L IS release were saying Canon could make a $4-500 lens, and clearly neither Canon or Nikon are super interested in that.

I also hope Canon wouldn't put IS in a 17-40 lens just to boost the price. For a lens whose primary use is on a tripod, that would be silly

I hear you there. but their current trend of releases tends to suggest that, if they do update the 17-40, it will most likely have IS built in.

that being said, I'd dispute the fact that the majority of its buyers use it on a tripod. I know lots of people that use the 17-40 specifically as a wide-angle walk-around (or hike-around, rather), and would love to not have to bring their tripod along.

You will see more of there 800 mm lenses sold I think than the 600 now. That MTF is unreal. Much better than Canon now. But it is rumored that Canon will announce the 800 II soon. I bet that bad boy will be lighter and just as sharp.

MTF tests from Nikon, Canon, Leitz, Zeiss , Hasselblad are real MTF tests and of the lens only

Actually, most of those published MTF curves are not real MTF tests, i.e. the manufacturers are not actually measuring the resolution of a real lens. Canon's and Nikon's published MTF curves are theoretical MTFs (as are Sigma's, Tamron's, etc.) - they are calculated curves, generated by a computer algorithm based on the optical design of the lens. AFAIK, Zeiss is the only lens manufacturer that published MTF curves that are empirically measured on a real production lens (not sure about Hasselblad).

Since neither Canon nor Nikon make public their algorithms for generation of theoretical MTF curves from the lens design, it's not really valid to compare them to one another, nor to Zeiss' real measurements. Comparing within a brand is fine.

Less MTF... more time shooting!

 

[sandymandy]

I think people with a normal income dont even think about getting the highend tele lenses anyway I just like Canon no matter what Nikon does. Im fine with my gear and so should u!

 

[Loswr]

I have already answer that, go back to page 2, BUT Canon, Leitz , Hasselblad Nikon etc has real MTF equipments and measuring of the lenses , not to be mixed by Photozone and others "MTF" tests .
There is no problem to measure a Canon lens at Hasselblad MTF lab in Gothenburg and compare that to others

I do not see an answer. Are you saying that the MTF curves published on Canon's (and Nikon's) websites represent real, empirically measured data?

I wrote

Which means estimating, calculating
And please, if you are going deliberately misunderstand me, keep going.

Ahhh...but we do know. Canon's published MTF curves are calculated/theoretical, not empirically measured.

You have two possibly conflicting statements above - "Canon, Leitz , Hasselblad Nikon etc has real MTF equipments and measuring of the lenses," vs. "Canon and Nikon has a predilection to exhibit estimated MTF." Certainly it's possible that Canon has the instrumentation to empirically measure lens MTF (as Zeiss does, for example), and yet chooses to not show those data for their lenses. What is your evidence that Canon has such instrumentation?

Here we go again. I have no idea, but Neuro sounds more plausible, as usual. :

 

[yogi]

Meant to say also: good luck Neuro ;D

Good night everyone. Sleep well and dream of L lenses

I can tell you people that I have got stringent regulations about my use of
language from CR, but sometimes I wonder if it not is better to tell some people here at CR that they have to large costumes and shall not discuss things they not have any knowledge/clue about.
Time 0318 so there will not be any popcorn for me
good night

Only a bombastic, arrogant narcissist would say this in a discussion with neuro. Good luck with your charts.

 

[Loswr]

This smells head -room over all, you didn't know how a sensor works, no cameras)

Actually, you were the one in error in the thread to which you're referring, and ultimately, you admitted it. We actually agreed on most points in that thread, though - so if I do not understand how a sensor works, then neither do you.

Regardless, the point about MTF measurement really isn't worth arguing over. Sleep well...

Plausible?
meet me with facts

Here is a fact. I had a bad day at work, and had to work overtime. Think I will quit for the night. Sleep tight and dont let the bedbugs bite.

Agreed. I've been on this forum less than a month, and I can already see that you don't argue with neuro. I'm glad he spends his time around here...

I feel bad for starting this thread. It really was only a piece of info! :-[
