Lenses / Re: Do all of canons 50 mm lens suck?

I would happily pay $1000 for a new 50mm f1.4L similar size to the exisiting and L build same as the 100 f2.8L macro with similar sharpness etc circular apperture baldes etc engineering plastics to keep is small and light
which is one of the benefits of the fiddy.

Thanks guys, yeah i'm not getting anything remotely that sharp :'(

I'm a little confused that you can make that assessment from a 640x427 jpeg.. If you really can tell from an image that small, you're doing something wrong or your camera or lens is incredibly broken.

I'm also a little confused by the wording of this thread's subject. Aren't all lenses "wide open" during autofocus? The aperture is only adjusted when the shutter is activated (or the depth-of-field preview is activated).
true I was just feeling sorry for myself yesterday so i spend most of last night doing detailed testing i posted all the raws this morning

with it all being so new i wish people would only post images or raws straight out of camera.
posting post processed images is fine for showcasing but none of this is about that its about what the camera can do at a base level. I think everyone know that a little PP can dramatically change an image from its raw state to present it in a completely different light.
leave the processed images for the image gallery at the moment htis is all about the gear and what it can and cant do.
I am concerned this new AF system may be a dud  :'(

EOS Bodies / 5D2 vs 5D3 ISO100 around 50 test raws
« on: March 27, 2012, 07:03:59 PM »
So I spent about 8 hours doing this last night
3 tests, all ISO 100

test 1 - the AF micro adjust method using the canon utility
test 2 - shooting a test chart off a tripod
test 3 - handholding a shot to confirm

all tests using center point only
I also turned off the in camera lens correction stuff
anyway all the exif data is there

test 1 and 2 lit by 4 5500K constant lights & shoot through umbrellas
test 3 ambient tungsten light at night

lenses tested
16-35 f2.8 II
50mm 1.4
Sigma 85mm 1.4
100 f2.8L IS Macro
70-200 f2.8L IS II
300 f4L (i had to bump iso on test 3 up to 800 for these being hand held)

I didnt test the 24-105 because my wife was out and had the lens but i will do it and add it in

during this i discovered to my horror that the kenko DGX teleplus 1.4 teleconverter does not work on the 5Dmk3
nice of canon to kill that for me :(  :'(

Overall I feel the images are sharper however I think the 5Dmk2 still beats the 5Dmk3
I have not done any detailed manual focusing tests yet and havent done any more AI servo tests using the 70-200 yet either... maybe tonight.

Anyway happy downloading and comparing.

So I have a the new 5dmk3 and a 50mm 1.2L.  I have been trying to get the micro adjustment on the lens just right, but but I figured out why it had been a bit confusing up to this point.  If I use the center point (or any AF point within the metering ring) I get spot on tack sharp AF on like 90% of the shots with 0 MFA.  BUT, if I use one of the outer AF spots I get pretty bad back focusing (like +15).  I thought maybe it was the body I had, so I just went back to the camera store and exchanged it for another body hoping that I would at least be able to figure out if that was the variable.  Turns out this body is exactly the same.  This makes me think it is either difficult for the AF to get a good lock due to the aberrations of the glass the closer you get to the edge, or something wrong with the lens itself (it is brand new and date code is uz0909).  I'm also just wondering if this is the price you pay with AF on really fast glass.  That is where you come in.  If you have fast glass (1.2) try checking the AF accuracy on center point and a more lateral point and lets see if we can come to a consensus.  I'm especially interested in 50mm 1.2 as thats what I'm working with.  I tested my 70-200 2.8 and it's pretty spot on with no MFA, on both center and lateral AF points.  I'll post a few test shots of my 50 when I get home later.
this could explain my wildly varied results too although i was deliberately stopping down to f2 or f2.8 to give it a bit of a chance also images are sharper there.

How is the back-button focus any different than pressing the shutter button halfway on subject, composing your shot with, then depressing fully??
Ok here goes

Situation 1 - shooting in a studio narrow aperture your distance to the subject not changing much you can focus onece then just shoot without having to keep refocusing if you are not moving, if you change position or distance you can focus again then shoot off a few shots.

Situation 2 - Shooting in AI servo you just hold that button down the whole time to make sure it holds tracking and press the trigger when you want (its much much better than the half pressing).

Situation 3 - Landscape on a tripod, frame the shot focus using the back button recompose to suit and now you can shoot at will without it trying to refocus on something

Situation 4 - use AF to aquire the target then MF to refine in this case hitting the shutter button doesnt try to refocus.

There are probably more but those are a few handy situations.

i have 4 580 exii and dont have any problems with them
i have heard they have an issue with the pocket wizard or the hotshoe becoming loose or something? i cant remember exactly, i know there's a DYI fix for that but i am not particularly handy with fixing/altering electronics, especially expensive ones

I use odins
2 odin transmitters and 4 recievers
piles of eneloops
4 yongnuo external battery packs (these are brilliant for $40 /each hold 8 extra batteries and your flashes go all day with faster recycle times)
580 ex ii are only $450 from digital rev

does anyone here own/used the 600ex speedlite yet? i know obviously if you live in the US its not out yet. however its currentlyu available in my country for almost $800. that is such a rip off IMO. i have considered buying the 580EXii but have heard numerous bad things about it.

i dont own a speedlite so my knowledge is pretty limited in this area

i have 4 580 exii and dont have any problems with them

if you buy a sigma buy it from a bricks and mortar store you can take it back to and let them send it in to have it recalibrated if it needs it, i love my 85mm now it's all sorted out

Seems to me to have been over sharpened

That, or the detail is simply overpowering. Probably a combination of both rendering a disgusting photo of a beautiful woman.

A few more pictures like that showing the D800 capabilities and the 5DIII will be the best seller :)

May be that will be 5D3's marketing line: we render soft images, so your models' faces will appear silky smooth!

yeah i think mine came with portrait professional built in... :( :'(

Look at her lower lips area at 100%  :o  :'( This camera is not meant for taking portraits of women.  :-X


ROFL that is sharp!

An interesting development tonight.  I have been working at +6 all day on  my 50 1.2 and been pretty happy, thought I might see a bit of front focus this evening, set back to 0 and everything is totally spot on.  Will check tomorrow once the sun comes up if it is the lighting or if it just needed a bit of working in as the lens and body are brand new (makes no sense, I know).
yes its wierd but this is my feeling that the AF is all over the place i had some lenses at -15 to plus 10 and back to 0
on my other cameras i performa astandard MF adjust once and thats it its bang on all the time
