Chuck Westfall comments on 5D camera banding issues Thursday, February 23rd, 2006 in Canon Camera | Hi, Folks: All of us here in the Camera Division at Canon USA are getting ready to spend the next 10 days in Florida working hard at the PMA show, so time for web monitoring has been somewhat scarce lately. In any event, as promised, Canon Inc. in Japan has indeed been actively investigating the claims of banding under certain conditions with the EOS 5D since the first reports surfaced shortly after the camera was delivered to the market. Here is what we have been told so far: “There may be cases where random noise or pattern noise [banding] stands out in images taken at high ISO settings. This is because the noise component is also amplified at high ISO settings. Various measures are taken to reduce noise, but the fact is that it cannot be entirely eliminated technologically. We are continuing to work on reducing noise even further.” “The following shooting techniques can reduce or prevent the occurrence of noise.” * Whenever possible, use low ISO settings (ISO 800 or lower) * For subjects that do not move, use One-Shot AF mode “Horizontal line noise may be somewhat more noticeable for the following six lenses when compared to other lenses, but horizontal line noise with these lenses can be reduced by replacing parts.” EF85mm F1.8 USM — Part No. YG2-0199-000 EF16-35mm F2.8L USM — Part No. YG2-2011-129 EF17-40mm F4L USM — Part No. YG2-2081-009 EF20-35mm F3.5-4.5 USM — Part No. YG2-0268-009 EF24-85mm F3.5-4.5 USM — Part No. YG2-0299-009 EF28-200mm F3.5-5.6 USM — Part No. YG9-2059-170 or YG9-2059-179 “Going forward, we will continue to work on even further noise reduction in the development of both cameras and lenses from now on. It would be difficult to completely eliminate noise, but we will continue to make efforts to reduce it.” That is all the information we have at present. If there is anything else, we will pass it along. Best Regards, Chuck Westfall Director/Media & Customer Relationship Camera Marketing Group/Canon U.S.A., Inc.

z Paul Says: February 23rd, 2006 at 8:30 am What about the 50 1.4 it clearly exhibits banding in ai-servo operation z Roger Says: February 23rd, 2006 at 11:03 am If you read carefully, he says those lens have “more noticeable” horizontal lines, it doesn’t mean other lens like the 50 1.4 does not exhibits banding…may be “less noticeable”… z Andy's Blog Says: February 23rd, 2006 at 8:58 pm Canon 30D… I’ve been a Canon 10D owner for quite some time now. In fact, when I found out that my wife and I were having a baby, I knew I needed to bite the bullet and upgrade from my point-and-shoot Casio 3000EX. Roughly $2500 later (camera plus lense…… z Digital Camera Information » Banding problem with Canon 5D Says: February 25th, 2006 at 4:20 am […] Source […] z Bill Says: February 25th, 2006 at 12:23 pm Concering this banding issue, I am furious with Canon. I bought the 5D in large part because I need a good low-light camera and it is kind of like false-adversting. On the one hand, Canon has given me a high ISO camera and on the other, any high ISO image that I shoot with that camera is likely to be ruined due to this horrid, horrid, banding - which goes way beyond noise. Also, the more I have used the 5D, the more I have discovered that banding can happen any time, with any lens, and with the AF at any setting. I traded my first body in for a second, but there is no difference. The one hopeful sign that I am seeing now is that Canon is at least finally admitting a problem. When this first happened to me, I spent quite a bit of time communicating with the Canon support people and in those communications I pointed them to online forums where other 5D users were reporting the same problem, and still they pretended as though no evidence for such a widespread problem existed. In addition to the banding, high ISO shots also yield a huge number of dead or hot pixels, spread throughout the image. If the image is reproduced at a small size, these are not too obvious, but as the enlargment increases they eventually become intolerable. z benjenq Says: March 3rd, 2006 at 10:40 am The following picture is a testing result from my own Canon 5D. 50mm F1.4,AI SERVO http://pic.twbbs.org/content.php?id=benjenq&album=D0AB94F2&photo=69E0DC66E0.jpg z Randy Vellacott Says: March 10th, 2006 at 11:41 am Forget the 5D ……..I have horizontal banding issues on my powershot G5. Images taken at ISO 50!! z randyv Says: March 10th, 2006 at 12:05 pm Oh and ditto to Bill and his experience with Canon Support. I have been a devoted Canon user for 30 years. No more, after my encounters with Canon Service in trying to discuss the banding problem. z Bob Says: March 26th, 2006 at 11:22 pm This is a fault of Canon’s CMOS sensor system and not of the 5D in particular. 20D users were howling about this 18 months ago. It is very pronounced in JPGs from the camera and in RAW images converted with Adobe Camera Raw. Raw Shooter Premium displays much less of an issue with the banding. To the poster with the dead pixels: this is also a common feature of Canon’s CMOS sensors If you want a really revealing http://www.dslrphoto.com/2006/02/23/chuck-westfall-comments-on-5d-camera-banding-issues/ 28/11/2006
