Unfortunately, it had to be returned....

[girlperson1]

I received the lens yesterday and immediately noticed a defect in or on one of the interior lenses. I had to send it back to Amazon. Replacements are on back order so when I'm due to get a replacement I have no idea. All I do know is that I'm very disappointed. Yes, the "defect" was casting a shadow into my images. It was clearly large enough to see with the naked eye.

Hopefully, once I get a replacement I'll be happy. I've included two images, one original, the other a crop, of the "issue".

I would be surprised if that spec on the lens was casting a shadow in your images. I think the more likely explanation is dust on the sensor.

Put another lens on the camera. Use ISO 100, aperture priority and f/22. Handhold the lens and take a photo of a light colored wall (make sure the camera moves around a bit during the exposure).

If you still see the spot, then you likely have dust on your sensor.

If the problem is dust on the sensor, then replacing the lens won't resolve the issue.

Would you post an image with that shadow?

BTW, if that particle is just below the front element, it would be probably easy to blow it off. Front elements on several Canon lenses I played with can be easily taken off - there are a few screws behind that black ring. You need to be careful when you put the element back not to turn it compared to where it was before (take a picture).

No dust on the sensor.

I don't fiddle about and take anything apart. There's no image of the shadow. I will say the auto-focus is amazingly quiet and FAST. I'm looking forward to receiving the replacement lens.

That is OK. I returned my 70-200/4 IS years ago for a similar particle inside. The replacement is clean.

I cannot escape the feeling that the lens with the particle was sharper... ;-)

Just saying.

Just saying.

They would not know.

 

[Snapper2013]

They always look for tampering when it comes to warranty work.

Sorry to hear that you had an issue with this lens, but I don't think it is appropriate to make a review based on this unlucky experience and rate it 0,5 out of 5. That's not serious and not helping anyone else here neither.

hope you will be happy with the new copy!

No dust on the sensor.

Out of curiosity, how did you determine it was a shadow from the lens, and not dust on the sensor? I am not disputing your findings, but I am curious as to how others diagnose problems.

Would it be possible for you to post an image showing the problem? I am curious to see what sort of shadow is being cast.

Apparently I have the same issue with mine. I just unboxed it last night and still haven't actually taken a picture yet though. It appears to be a particle on the inside of the front element and it actually moves a bit when I move the lens. Behaves like a very light weight particle (like maybe a piece of Styrofoam). Trying to decide whether to return it or not. I am not going to take a brand new lens apart but I am also lazy and hate to go through the return process for a backup lens that won't get used all that much (I have the 100-400/LII for most of the time).

Very hard for me to believe that it will affect an image but irritating to have that in a brand new lens. Implies they aren't assembling these things in an ideal manufacturing environment if these particles are showing up right out of the box.

I thought there was a something on my new 70-300 ii as well, but it turned out to be a reflection from something internal. I would move the lens around, and the spot would move. But in certain positions there was no reflection. My photos so far have been sharp, clear, and as the OP stated, lightning fast focus. I'm am really loving this lens so far.

Yes. That got me doubting what I was seeing because I also saw two small point reflections like you describe. This was definitely a good sized particle though. I decided to return it rather than keep it and be irritated about it. Since it's on back order I'll have to wait to get the replacement.

I received my replacement lens which I ordered from B&H. I'm waiting for Amazon to refund my money on the returned lens. The replacement lens seems fine. Nothing odd floating around inside the lens or sticking to the optics or creating odd reflections. I haven't used the new lens yet but as soon as I do, I'll post my comments.

Unfortunately, I didn't save any image files of the shadow. Usually, you can figure it out by trying more than one lens. Dust and dirt on a sensor will show up in every image, regardless of what lens you use.

I think the new copy will be fine and once I test it out I will change my rating.

The second lens I received seems clean. It's very annoying to be honest.

Did you mean "It's very annoying to be honest" or "It's very annoying, to be honest"?

It's a pity you've skewed the ratings for this lens by awarding it a half out of five all because of a little speck. Perhaps you could review it again after you've used it a bit ...

Ah, I see you've already said you will. ;-)
