Be Aware of Nikon 24-70 F 2.8 N Lens.
I heard some rumors regarding Nikon 24-70 N lens that light leaking happens through focus finder n tested it by myself... It was not rumor... it really happened.. I posted my test on youtube. check it out. http://bit.ly/cbK3QN Jul 02 10 11:19 am Link Great video. Let us know what Nikon does for you Jul 02 10 11:26 am Link lovely. *note to self: don't sell 28-70/2.8* it strikes me as particularly dodgy of nikon to suggest gaff tape to fix their problem. ayayay. Jul 02 10 11:44 am Link When I shoot at ISO 1600 at 10sec. I do so because I'm shooting in extremely low light, and when shooting in extremely low light I don't have any bright light filtering in through the focus finder. I've been using this lens for a year now and it has become my favorite lens, I'll keep an eye out for the problem but so far have not seen this problem yet in any of my photos. Jul 02 10 11:54 am Link Damn!!!! Mine just failed the test. Luckily I have gaffers tape. Is that really the solution from Nikon so far? Jul 02 10 12:06 pm Link Mooyo wrote: Well the solution is really easy: just put some gaffer tape over whenever you are going to use it for long exposures at said focal length and done. A mistake from Nikon? sure, Something really dramatic? no... Jul 02 10 12:06 pm Link My favorite lens for the past year. Never had a problem. I imagine there are a few thousand other Nikon shooters around the world who could say the same thing, but people rarely go on forums to report NON-issues with gear.

Jul 02 10 12:29 pm Link Unfortunate issue yes would it stop me from buying a great lens no if set up under similar rarely used scenerios I would imagine a number of lenses could have this issue. How many times are you setting up with the focus screen 5 inches from the center of your softbox with the screen perpendicular to the light coming out? And I would imagine if you were worried about it a regrip of your hand would do the same as the gaff tape solution. Jul 02 10 12:32 pm Link [The problem also occurs when shooting under strobes at ISO400/125. So yeah. I'd consider that something dramatic.] I guess using my 2400w Speedotron lighting system I still never found a need to shoot at 400 ISO Jul 02 10 12:41 pm Link thats it, i'm selling all my nikon bodies and lenses...i'm switching to canon....

Seriously, I love my 24-70 and never have any problems. Jul 02 10 12:51 pm Link William Westerhoff wrote: Just because the OP only tested the issue out down to 400, doesn't mean it has no effect on other iso settings. A light leak on your lens is a light leak on your lens. It's still there no matter what iso you use, it just may not have as dramatic an effect.

I am seeing the same as well, it seems to be a sweet spot just like he said between 50-55. I haven't notice it causing any problems, but it is deffinitely there. Jul 02 10 03:42 pm Link Gaffers tape as a suggested solution? Wow... Jul 02 10 03:45 pm Link I could not make mine do it. I tried: ISO 4000 10 sec f2.8 Cell phone light ISO 4000 1/125 2.8 WL 800 at full 24mm, 55mm or 70mm Wonder if it was a bad batch or a grey market. Jul 02 10 03:53 pm Link Great. I just ordered one this morning. I guess I'll find out next Thursday when I get it. We'll see how good B&H are on returns.

When I am shooting at that high of a ISO, I don't have any backlight to worry about. Jul 02 10 04:27 pm Link Confirmed here. 10s f/2.8 at 200 with an LED mag light pointed directly into the window. I took a light reading on the mag light, and calculated that the phenomena must be about 18 stops below ambient. Jul 02 10 04:30 pm Link for whatever its worth. at iso 3200, 30seconds exposure, f/22, f/11, f/2.8 @~50,53 and 55 mm using a single speedo head on a 2400w/s pack, using a snoot, focused on the little window.... perfectly black frame, nothing on the histogram. only did one test at lower iso, of course, nothing. tried 70mm and 24mm, nothing. Either I was lucky and got a good copy of a great lens, or you folks were unlucky and got a poor copy. Seems like a lame response from Nikon, I would insist on a copy that didnt leak. Jul 02 10 05:52 pm Link well... it's true that light leaking happens at certain circumstances but at the same time, it happens... which is supposed to be not... I personally think it's more of fundamental issue. and I tested it with iso 200 / ss 1/125 sec... so... I am talking with other photographer in Korea and try to collect some pics with same issue. I will let you know when I got more info. Jul 03 10 12:41 am Link Lately, it seems like Nikon is doing their best to boost Canon's sales. Personally, I'm in the midst of a problem with Nikon, but I'm keeping quiet on it until next week to give them a chance to do right by me. Needless to say, I am very displeased with the situation I've encountered with their service department, anyone knowing the facts would probably think I'm being incredibly generous with trying to give them a chance to make up for this. Jul 03 10 12:48 am Link Um, this puzzled me as to why people are thinking there is a problem. If it is a problem with one lens it will be a problem with ALL lenses. The D700 & other upper end bodies have a viewfinder shutter for when the camera is being used without an eye in place. The "problem" of light coming in throught the viewfinder has existed to some degree ever since the first SLR. As with the hysteria that some people whipped up on the internet over the molding marks in the 70-200 GII light baffle, I will not be having any concerns or doubts about the quality of the product inflicted on me by this.

The "problem" of light coming in throught the viewfinder has existed to some degree ever since the first SLR. It sounds like the light leak is coming through the focus "window" on top of the lens -- not through the viewfinder/eyepiece.' Jul 03 10 01:12 am Link This is such a non issue. For the record, I managed to make this happen @ 50mm shooting on a D300 ISO HI 1.0 (6400 Equiv), f2.8, 30s with a lamp hard against the 'leaky' focus screen. I then tried to correctly expose that light at the same focal length. A shot of ISO HI 1.0, f2.8 1/8000 is still over exposed, but that's as fast as I can get and seems plenty to prove the point. Someone want to work out how many stops there are between 30s and 1/8000s? If you have a light falling on your lens that many stops above your scene, then frankly the equipment is not the problem. Jul 03 10 01:15 am Link The Other Place wrote: You are correct, as shown in the video posted above the light is coming in via the lens. Jul 03 10 01:22 am Link Nikon can easily fix this solution. All they have to do is include a complimentary roll of some black tape with the lens.. simple fix.. I wonder why anyone would be upset after spending all that money on the lens ? LOL Eeesh. I'd be sending that lens back with a jar of Vaseline Jul 03 10 01:44 am Link Jon Dawes wrote: The difference is, is that lenses are not supposed to leak light. Viewfinders on the other hand do leak light, and it's common knowledge amongst experienced photographers that they do. There are viewfinders specifically made with internal shutters that will block out light that leaks in through your cameras regular viewfinder when doing long exposures or shooting in conditions where this may be a problem.

Yes there are methods around to combat it, but lets face it, 99.9% of people take no steps whatsoever to combat it because it isn't an issue. This lens leak is about the same in terms of effect on images. Jul 03 10 02:46 am Link I also forgot to mention this thing has been only happened at full-frame body Jul 03 10 03:01 am Link I use the 24-70mm all the time on my D3 and never had any light leak problems.

Jul 03 10 05:21 am Link Major issue or not, extreme conditions or not... the bottom line is: IT DOES LEAK! All other lenses don't do this (anybody tested theirs?) "Eternal vigilance is the price of liberty." Tommy J. Jul 03 10 07:16 am Link I just watched the video. I had no sound earlier today. This is almost silly! I just repeated this same test, with the same methodology on two other Nikon lenses and a Canon 24-105 and they all do the same thing. I think if you try hard enough, you can force any lens to leak light. Jul 03 10 04:38 pm Link |
