Lenses / Re: Strange Lens Flare (Sigma 35mm + MRC filter)

Here's my snapshot from the other night.

ISO 3200

Like I said previously, I thought the flare my just be caused by my filter. After reading this thread I'm 95% sure it's just the mirror box in the camera now. Not a big deal... I've never had this type of flare before in any image that really counted.

Just want to add that I was shooting with the 5D2 late last night with my 24-70 f/2.8 II and experienced this same sort of flare in one or two of my photos. I put it down to the filter at the time, but after reading this thread regarding the phenomenon occurring with only the 5D2, it makes sense as I've never seen this lens have that flare on my 5D3.

Looks like its nothing to worry about. I'll post my flare picture tomorrow from the 5D2 and 24-70 II.

Another point: don't suddenly swing the lens when the IS is being turned on or off (before you hear the IS park noise), or you can risk damage the IS module.

Interesting point. I have never heard that one before either.

Thank you Takesome1 and Neuro! I appreciate the quick help!

Lenses / Just bought a 70-200 f/2.8L IS II - A Few Questions
« on: December 31, 2013, 03:08:33 PM »
I finally sold my non-IS 70-200 and updated to this amazing piece of glass. So far I am incredibly impressed with the image quality it produces on both my 5D2 and 5D3. I just have a few questions regarding the proper use of some of the switches:

- I have heard in the past that it is not good for a lens to switch from the image stabilization off when the camera is powered on. Does it matter if I switch image stabilization modes from 1 to 2 when the camera is powered up, or should I turn the camera off before I make the switch?

- Another thing I noticed is that there is a slight wiggle, or a bit of movement left and right, when the lens is attached securely to the camera body. Is this normal to expect this slight movement?

Man, I wish I had this lens. Having that sort of subject isolation is incredible. The bokeh is insane!

Beautiful shots everyone! :)

Forgive me for bringing this up again, but after being burned and frustrated by the 24-70 II, let me voice my opinion once more:

Just be careful when you purchase the lens, and make sure that you test it thoroughly to make sure it is working properly. It is my feeling, and I am sure some would back me up on this forum, that Canon is suffering from some serious quality control issues with this particular lens.

I, myself, experienced a severely decentered element on my first copy, clicking sounds from the zoom on my second copy, and another decentered element as well as squeaking on my third copy. It wasn't until my fourth attempt that I finally managed to get an acceptable lens.

I also want to mention that I ended up purchasing the lens twice. My first copy was sent into Canon after less than a month's use (unfortunately I passed the return date for the lens at the store) for the decentered element. Canon kept it for six weeks, twice as long as I had actually had it in my possession, only to return it to me and saying everything was in spec when it clearly was not. I called up Canon's Canada CPS and explained why I was not satisfied with the repair and the lady I spoke with told me Reikan FoCal could not be trusted and that my lens was properly looked at and adjusted by their technician. I told her she was wrong and she replied by telling me (her words) that I could "waste time sending it back in, but chances are the techs wouldn't do anything to it."

At this point I lost my nerve and went up one side of her and down the other about how awful her service and response was, and that this whole ordeal is unacceptable for such an expensive and brand new piece of equipment. Obviously, coming from her previous response, she still did not care and just said "send it in."

Having sold my trusty 24-105mm to pay for this first 24-70 I was kind of at a loss for having a decent walk-around lens. I was also determined to find a good copy of this lens so I went and bought my second copy from another retailer here in town. Thankfully this time I was cognizant of the problems too look for and returned it as many times possible until I was satisfied.

Unfortunately I managed to wrack up quite the nice credit card bill purchasing the lens a second time.  I still own my first copy and am considering selling it at a massive loss, or sending back to Canon for repair and then trying to sell it. Either way, I've never been more frustrated with a product or the customer service of a company before.

As far as my working copy goes: the images are fantastic and incredibly sharp. It runs circles around the 24-105.

From a moral stand-point my own feeling is you acted poorly.

There's at least one other long thread on this.  The consensus was that most (myself included) who bought the 24-70 II subsequently sold their 24-105.

Yeah, but most of the other threads are about people not wanting to sell their 24-105 for the low price it is fetching.  I was hoping for a little more input on IQ.  Are people happy b/c they are getting better images?   Is it noticeably sharper for those who print bigger? IQ discussion anyone?

If you can get a good copy of the lens it's much sharper, and the images will be much more contrasty. I, myself, had to get four copies of the lens to finally be satisfied, and even then this copy I have now is not perfect.

The one thing I will say for the 24–105mm is that it is a robust lens that has been around for a long time and has very few problems.

I do regret selling mine, only because I almost completely stopped taking pictures while my 24-70 mm was in for repair at Canon. Unfortunately I had to use the money from it to pay for the new lens.

It's outrageous, egregious, PREPOSTEROUS!

Mail-in-rebates don't work if you purchase from B&H and have it shipped to Canada, correct?

May you sell with the in depth explanation.

I'm an honest person, I'm not going to deal with someone unfairly. What's the purpose of your post?

I just spoke with CPS on the phone. Basically they told me that my tests were inaccurate, that my lens was within specification, and that if I send it in again there would be a good chance of nothing being done.

I can't believe the poor customer service I received, especially after paying $100 for their damned CPS membership.

I am now going to sell the lens at a loss.

If you are sure it an accurate test, this is not normal for this lens.

I have run the same test on several copies.

Most copies would be at the best around F/4 with almost no drop of at f/2.8.
Some copies would  be sharpest at f/2.8.

The curve should remain almost level after f/4

I am sure it's accurate. It's how I have tested all my other lenses and I have never seen this.

Thanks for the input.

First to call the store I bought it from to chew them out for not giving me another copy and making me go through this, and then a call to Canon to see if I can get this replaced.

For comparisons sake, here is an aperture sharpness test I took with my 100mm Macro L last night at 5.3meters from the target.
