Re: Canon 50mm 1.2L HELP!!!

For what it's worth, I have the same lens, utilized primarily on a Canon 5DsR.

The one variable I do not see mentioned, in the background the sky appears overcast, I have experienced the same effect when set to manual mode, even shots seemingly taken close together. 

With a wide aperture, especially f1.2 I noticed it more, right out of the box.

And especially with an overcast sky, did not seem to see it on a sunny day, so my theory, and correct me if I am wrong, with an ISO of 1600 if the light through an overcast sky suddenly increases then the exposure will be affected, so I switched to auto ISO, and never saw it after.

The 50mm 1.2 L, is not what I have found to be the easiest lens I have to use, it's not like the 24-70 which percentage wise just seems to nail 99% acceptable.

Please relay your outcome as if it is defective, so far mine has been outstanding.

The EXIF data is available for both photos. The EXIF data is identical for both photos, and they were taken at the same time. 

That means it doesn't matter what the metering mode was, or what shooting mode the camera was in.  All it means is the lens is defective and it is most likely sticking aperture blades.


My MacPro is showing "Metering Mode = 6".  If you can read it, then please share.  What is it?

Fearing I may be reprimanded again, the lens needs to be tested on a different camera. It has to be confirmed that the lens is at fault first.

Waddizzle is right to query his point.  Just blindly sending the lens back and replacing it with a different lens may not fix the problem.

Re: Canon 50mm 1.2L HELP!!!

The suggestion that the aperture blades are sticking and the cause of the issue is a possibility but it is certainly not a probability. Especially in a brand new lens.  It needs to be tested on a different camera. This is too simply to argue or dispute. Just give it a try on a different camera.  Then if it still exhibits the same condition, I am all in but not until that happens.

 

This is as nice as I can be Mods!

Re: Canon 50mm 1.2L HELP!!!

THANK YOU everyone for your responses!  I am an extremely BUSY mother of 2 young boys and now teacher, due to Covid and e-learning.  I have the early mornings and weekends to do business related work.  

My husband and I have recently had to purchase a new water heater, cooking range, refrigerator, dishwasher, washing machine, and air conditioning unit among other things around our home.

When you spend over $1000 on a brand new product, I really expect that it should be in exceptional working order right out of the box.  Perhaps my expectations are unrealistic, but when I am purchasing a TOP OF THE LINE lens, I don't want to have to worry about it being a LEMON and having to go back and forth with Canon on getting it fixed... or having them presume it's NOT the lens (when all logical testing suggests that it is).

 

For shi*s and giggles, I will test the 50mm on my other camera body today.  I'm rather confident the issues will arise yet again.  

I do appreciate all the feedback and suggestions, but I am 95% certain I will be sending this lens back to Adorama.

THANK YOU ALL and enjoy this beautiful day!

Great!  Smiley Happy   If it exhibts the same issue then you will have confirmed it is the lens at fault. If it does not than a new replacement lens will not help. If you need help at Adorama contact Helen Oster.  She is excellent to work with and will make it right.

 

 

Pretty nice, don't you think, Mods? Smiley Wink
