Firm ware updates for lens?

jimmy637 — Sun, 14 Aug 2016 15:26:11 GMT

Here is my situation, long time Canon DSLR user, purchased 7Dii, when using my EF 300mm f4 lens the 7Dii the lens did not recognize the lens for lens aberration correction. I sent the 7Dii in for repair because it was not giving me good focus. it was still under warranty. got it back and still did not have great results with 300mm f4. Sent the EF 300mm f4 in for repairs not under warranty my cost. Now the 7Dii recognizes the EF300mm f4!!!

So here is my question:

When I put other lenses on my camera and check for lens aberration and the lens is not recognized, do I have to send in my lens to have them updated??

Is there something Canon is not telling us?

I ask this because I was ready to sell every thing and switch manufactures because I have had a year of frustration with my 7Dii and was about ready to give up on photography with DSLR camera's and use a cell phone or point and shoot.

You now that there are 1000's of 7D Mk II owners that use the ef 300mm f4L with geart success. I am unclear as to what exactly is your issue. What do you mean, the 7D2 doesn't recognize the 300? Can you post a sample of what is going awry?

I was asked what was going on.

In the menu of your EOS, I have 4Ti and a 7Dii so i will use those for reference.

4Ti , firm ware ver 1.0.4. Menu 1st camera tab, 5th on list "Lens Aberration correction", Set, now look at the information for the attached lens. I have the EF400mm f5.6L and it tells me no data., tried with EF-S 17-55mm f2.8. and tells me correction data available, EF300mm f4, no data.

7Dii ver 1.0.5 same menu selection 1st tab 5th down "lens aberration correction", EF 400mm f5.6 correction data available EF-S, 17-55mm f2.8 tells me data available, EF 300mm f4 tells me data available!

Well looks like it is not the lens, but the camera that does not recognize the lens.

I wonder how I get the camera to recognize a lens?

So before I got the lens and camera repaired (7Dii) the EF300mm f4 was not recognized, not sure about the other lens because I was only interested in the 300mm at that time. Also now that i think about it. I do not remember if the Camera repair updated the data for the lens or the repair of the lens updated the data for the lens. After looking at the two scenarios i would think that the repair of the camera updated the information.

I think I have updated the T4i to the latest firmware and still the T4i does not recognize the all the data for the lenses.

Another thing to ask is if the data is not available does it affect the use of the lens in general?

Oh Wow!!

You can use EOS Utility to add lens data to your camera.

Please explain?

I looked for updates for firmware for my lenses, EF 400mm f5.6 has no firmware, EF-S 17-55 f2.8 only shows up on a Mac and the same for the EF300mm f4 only shows up on the Mac and not on my PC?

Looks like i have to down load firmware on my mac for the 300mm f4 and put it on my T4i?

It is not in the lens. It is in the camera. From my T6S manual:

Sorry, but this does not seem to be so. you can not enable if there is no data to enable?

For my camera, at least, you can use EOS utility to download data for new lenses to store in your camera

Canon cameras get firmware updates, but I'm not aware that there's any such thing as a firmware update for a Canon lens. What there is, is lens aberration correction data, which is lens-specific (not camera-specific) and can be downloaded to the camera via EOS Utility and/or applied to RAW images via Digital Photo Professional. I have the 17-55mm f/2.8, and I've had no trouble installing the lens correction in DPP on a variety of PCs, from Windows XP through Windows 10.

Can you be more succinct and specific about exactly what your problem is?

I get all of that except the last sentence. Are they saying that if a lens has been mounted on a camera that has that lens's correction data installed and enabled, the lens will come away with the correction data permanently applied and can make use thereof if it's subsequently mounted on a different camera? If so, that's certainly news to me.

tried downloading the eos utilities instruction manual on my PC and it got lost in the files?
Please tell me i don't have to be computer expert to get my camera to recognize my lenses?

Since cameras and lenses are now computers, I guess so. You can always go back to film.

I read that too mean that not all lenses have correction data available. For example, for a long while, there was no correction data available for the latest "nifty fifty". Canon finally added it to DPP last fall, which finds its' way into cameras. Also, third party lenses will not have correction data in the cameras, either.

You have to be at least computer literate in order to make sensible use of any digital camera more complex than a cell phone. I'm sorry if I'm the bearer of bad news, but there it is. There are many things in life that one has to learn how to do.

This is not so or my T4i would have see the lens data that was available on the 7Dii?

Re: Firm ware updates for lens?

kvbarkley — Mon, 15 Aug 2016 20:36:24 GMT

I am guessing that having the correction data in the lens is something for the future, but that my T6S has hooks to let it use this new data, much like the flash sending color temperature data to the camera.

I have yet to see it mentioned in a lens data sheet or spec.

Thanks for your input, I think this email chain should be ended.

Update to tread.

Using the the EOS utility for the 1st time user.

From the Canon web site, I am Canadian, http://www.canon.ca/inetCA/en/home, Click on Support and Drivers, top right side. Click on Consumer & Home Office, Click on Drivers Software & Manuals, Enter/find your model number, Eg; EOS Rebel T4i click on GO.

The complete list of down loads appears in a few seconds and provides the down loads by category.

In the Software Applications click on EOS utility zip file, go to the bottom of the new page and agree.

The file will down load.

After down load is complete find the file, I used file explorer, click on file and follow the instructions.

After you complete the quite simple instructions look for the the program,I use the windows start tab and the reference was there or do a search for EOS Lens Registration Tool.

Note that you have to have your Camera connected to your computer for the next step, use the mini usb to usb cable that came with the camera then turn on your camera.

A new window/drop down will appear and this is when you get to use the lens registration to add your lens data to your camera.

It is an easy task, click on the tab for the lens aberrations and a list with all the lens will appear. You can search buy categories, tick off all the lenses you want. go the bottom of the page and click on the OK and the program does the rest.

I may have missed explaining the steps or tabs exactly, i was writing this from memory, but you should be able decifer what is required.

Good luck
