Question about Sigma AF 70-300mm f/4.0-5.6 DL Macro Super Lens for Canon-EOS

Err 01 Communication between Camera & Lens is Faulty

I've just purchased a Sigma 70-300 F4-5.6 lens for a Canon EOS 450D.

When I take a picture I get an error message ERR 01 Communication between Camera & Lens is Faulty Clean the Len Contacts.
To take pictures I have to switch the camera off after taking a photo then on again to view what I have taken a photo of.
Please help as I have very little knowledge of this sort of thing and would appreciate any help greatly.

    Just installed an old canon 28-90 EF lens on a new 450D and received the same problem. Autofocus works, confirmation works. It could took 2 pics for me and showed them. (although they were not sharp at all). On the third time camera reported err 01 and that`s all

Cleaning the contacts did nothing for me. what ended up fixing it was turning the camera to AV mode and setting to the highest f value. (f22) and then taking a picture. after that i was able to change it to what ever and resume as normal. hoping i dont see that error again.

Most of the old Sigmas have problems with the Digital Canons. Sigma didn't buy the EF patent so they tryed to reverse enginer it. The "BUG" is regarding aperture. you can only use then in AV mode (the lowest F in you lens). I use a Sigma 70-210 and a 70-300 APO this way.
Only the new Sigmas (it has DL on the name) are fixed not to return that error.
PS - If the lens is in any other F that it's not the lowest one it will always give the error (even in AV mode). You need to go into a 35mm Canon with EF and set it to the lower F. Then you can use in Digital EOS Canon Cameras.

    K I am not sure I am understanding this well enough. I also have a 70-300mm DL, I can not get it to take sports photos. Low light..Dark. Or long distance as I should be able to. I also ONLY on Sports and Dark shots I am getting a message saying that there is a communication error. between lens and camera.

  • HELMI_07 Feb 04, 2011

    HI.. Thanks for the tip.. I just purchased the 70-300 lens and it didn't work in manual mode...
    I tried it in auto mode and somehow it works fine... I then tried ur tip by lowering the F to the lowest F and it works even in manual mode.. THanks for this....

  • Fongolicious Apr 09, 2012

    I had the same problem as HELMI_07. I have a Canon 60D dSLR with EFS 17-85mm lens. I've used it manually before. But halfway through an outdoor excursion I had the err01 message. If I put it on auto or semi auto it worked fine. When its on full manual I encountered the err01 message. I switched to my 50mm f1.4 prime and it was fine on all modes. So it must be the 17-85mm lens. After reading this post, I just tried reducing my f to the lowest number (widest setting) and did a few test shots and it worked. Thanks.

I had the same prob with the Sigma lens [70-300mm af] and was pulling my hair out. I have a new Canon EOS 40d that would constantly give me the dreaded "err 01". No matter how much I cleaned the contacts or adjusted the aperture, nothing would work. I tried turning the auto focus off and on, pulled the focal length in and out, nothing. I ended up buying an after-market battery grip on ebay [$120.00 and came with two batteries] and had another go at attaching the lens. Straight away, bang, it worked. It seems, at least in my case, the single battery in the camera just doesnt have enough oomph to run the lense. It even works now in maximum burst mode, which is what you really want for shooting fast moving distant events. I'm stoked. [that's happy in aussie slang.] Hope this helps you out.
Regards
Jason

    I have the same problem with my Canon Eos T4I and already own a after market battery grip so I believe I will try this. Great suggestion and hope it works.Just got the lens used and don't care to send in for repair. I am a little mechanically inclined so I would rather take care of the problem myself instead of paying someone else to repair.Thanks for the suggestion. Tim

I have this same problem, with a canon T1i. i did this n it works out:
switch off then switch on ur camera. DONOT FOCUS OR do anything. put camera to AV(aperture priority) and set to lowest F no. 4 in this case, point , focus manually --shoot! works all the time! PS. this is a software bug error not a physical error, so DONT clean the, contacts, dont press down n stuff!
njoi!

    I have the sigma 70-210. It seems to me that the EOS1000D body does not recognise the max f stop is 5.6 and in sopme situations tries to shut it down more than this causingthe crash and err01 message. I have managed to take photos at f5.6 by scrolling the thumbwheel down to f4 in the AV mode, taking a picture and then the camera seems to work in any other mode. Keep an eye on the f setting in the viewfinder before taking the picture to make sure f stop is niot more than 5.6.

Try to clean the electrical contacts between the camera and the lens with an eraser. Be careful not to let any debris fall into the camera body. If this lens has an aperture ring, set it to the minimum aperture (maximum number available)

Okay so i have a similar problem. On a 40D with the 17-85mm lens.
I haven't found anything useful re permanent fixes. It seems this issue is widespread and apparently due to bad build quality..
TEMP FIX: I leave the aperture at 4 and its fine but when i put it higher i get err 01 then i find if i zoom a little anything past 24-35 range and i can jack the aperture up as much as i desire. Just a little hint so you dont ditch your lens altogether. peace

There is aparrently a similar problem not just with your Tamron lens, but also with Sigma lenses. I have just been given the Sigma 70-300 APO for Christmas for my 450D. I am somewhat disappointed. In full auto mode (idiot mode) only it seems to work fine, but in P mode and TV, in which I mostly work, it returns "comunication between camera and lens is faulty,clean the lens contacts". The contacts are not dirty - just to be safe I cleaned them with a trusted contact cleaner (I'm an electronics engineer and know about contacts). With my daughter's 350D it will not work at all.
These two manufacturers are of course manufacturing lenses in competition with Canon !!! Canon lenses are good, the top of the range are argueably if not possibly the best available today -but at a price only the professional or banker can afford (sadly) I've borrowed a couple of their top lenses in the past - wow!
I am going to try a firmware update, if this does not work then I will contact both Canon and Sigma. Perhaps they will have a solution. I doubt it, the problem has been known for a long time it seems. Look into other Forums for help as well. The problems are varied and sometimes erratic. Hope this helps ... OK, not really !

I have the same problem with my newly purchased 50D and my old Sigma 75-300 that I use with my 650 EOS 35mm. The Sigma is the only lens that I have a problem with and it works fine on my 35mm.

I have found that putting a moderately slight downward pressure on the lens works. The contacts are located in the bottom portion of the lens/camera interface and this seems to increase the contact between the two. I hold the lens at about the halfway point when I do this, with my hand placed on the side to top of the lens, pulling down. So far, it does not appear to interfere with the pop-up flash coverage, although I usually shoot with a Speedlite.

I buying a battery grip because I want the extra battery life, not because of this. But if it helps with this problem, that's o.k., also. I know that putting the slightly moderate pressure down on the lens will not hurt the camera (or the mount), but still, I shouldn't have to do that to operate it with this lens.

I've just purchased a new Canon EOS 60D, and experienced this problem when using my 15 year old Sigma 170-500 EPO lens. The work around, as MarsWalker so helpfully points out, is to use the widest aperture setting on the lens. I found that any other aperture setting other than the widest resulted in this error.

Thanks for all that. I have 450D, too, and sometimes use a Sigma fixed focus 400mm on my EOS10 and Rebel EOS500 with no probs so that's why I bought the Canon camera to replace them - I hoped! But, like others I am getting the message: Err 01
Communication between
The camera and lens is
Faulty.
Clean the lens contacts.

Cleaning didn't work and I used alcohol to clean the contacts. I had a theory about battery poke and maybe that's the real prob. Gonna try the pressure trick and then might see whether there is a way to extend the contact pins a fraction.

I have a Sigma 70-300 mm lens 1:4-5.6 DL. it works on my EOS 450D does it also work on an EOS 500D hoping for a reaction


Hi

Here's Sigma's Webpage. You should call them at 1-800-896-6858 to verify this lens will work, as I can not find a listing for the "DL" lens you have.

My initial response is that if it fits the 450D, it is a Canon mount and should work about the same on the 500D assuming both cameras have the same size sensors.

Again, a free call to the manufacturer is going to provide the best possible information on compatibility issues between this lens and various Canon camera bodies.

Good luck!

According to Sigma, your lens should be fully compatible with your camera although there will be the usual 1.6x crop factor as the lens is designed for a full frame sensor. This would not cause your Err 01 fault though so you should return the lens to your dealer for refund or exchange. Failing that, consider claiming on Sigma's one year international warranty. The warranty is ONLY valid if your lens was supplied with the Sigma Warranty card. All new Sigma lenses supplied through official resellers include the Warranty Card. You can find more details about where to send your lens for a warranty repair by clicking here.

Good luck, and please take a moment to rate my reply.

Canon leads the current world market in lenses with their L-series lenses using fluorite rather than other manufactures use of glass. however, they do not make money when we buy 'other' brands of lenses and have kept a certain amount of their body to lens, coding as propriatary. the problem you stated is a common complaint with all second manufactured lenses and the only real solution is to put a canon lens on a canon body.
