I recently purchased a Canon 6D....

PhotosByNeva — Tue, 20 Oct 2015 23:26:35 GMT

I wanted to upgrade from my Rebel. I have several lenses already and noticed that when I use them on my 6D there is a round black ring around the outside edges. Upon reading it seems that the Rebel has a "cropped frame" and the 6D has a "full frame". Does this mean that I have to get all new lenses to use with my 6D, and make sure they are EF?

Yes. I am surprized you were able to even mount an EF -s lens. Do not do that anymore as they are not meant to go together and in some cases you can damage the camera or the lens by doing so.

You need lenses for full frame Canon cameras. Either Canon EF lenses or 3rd party lenses made for Canon full frame mounts. The different manufacturers (Sigma, Tamron, etc) use different letters to designate FF vs. crop lenses.

I have found a way to cheat and mount an EF-S lens on a full frame body. I used to use an extender and close-up filters on my Rebel as an inexpensive way to explore macro photos. After I purchased a 6D, I noticed that the extender was EF mount, but the bayonet to mount a lens had both a red dot and a white one, just like my Rebel.

Sure enough, with the extender attached, I could mount an EF-S lens without issue. Of course, I could see the entire image circle. But, I thought I was pretty clever just the same.

"I have several lenses already ..."

Are any of these Canon brand lenses? It is possible for the rear of the lens to strike the mirror. It can be cracked if EF-S lenses are "modified" to fit on a 6D. Sigma and Tamron lenses will bolt right up and will cause the black corners.

The "S" in EF-S stands for short focus. That is why they have pin to make mounting impossible.

Do these lenses screw on to the front of existing lenses? Or do they mount directly to the camera body?

The 6D is indeed a full-frame sensor body and it requires Canon EOS "EF" lenses (without the "-S" suffix) It can also use the EOS TS-E and MP-E specialty lenses. You can use third party lenses if they are designed for use for Canon EOS full-frame bodies.

They screw on to the camera body. I didn't do enough research before my upgrade because I have several lenses that fit my older DSLR Rebel and I guess I have to buy all new lenses for my 6D. I just paid over $600 for a new Tamron Piiezo Drive 16-300 mm lens that won't work on my Rebel. I get two shots and it shuts down my camera, same problem with the 20D I had. It works on my 6D just fine except it isn't a full frame lens apparently.

The specs clearly state,

"Tamron Di-II lenses are engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses also include properties to optimize digital imaging performance."

So that is the problem with that lens. Not all third party lenses are compatibile with all Canon cameras. Even the ones that are designed to work on a FF and/or APS-C, may not work correctly. Most newer versions do, however. Sometimes, try before you buy is a good rule. Plus third party lenses do not have the altered mount to prevent you from mounting the wrong lens as you have found out. Without modification of the mount, you can not mount a Canon brand ef-s lens on a 6D.

So what you are saying is even though Tamron, Sigma, or other brands that state that they will specifically fit certain Canon Cameras, they don't?

I had good luck with the Tamron that was on my 20D and the Sigma that I bought for my Rebel, they have been good lenses. I always read plenty of consumer reviews before I buy. I do not always have the option of "trying" before I buy. How would I go about doing that? Renting?

I appreciate your input on this matter. I have sold a few of my pictures and I wanted a better quality, newer camera. Couldn't always afford the Canon lenses, so the less expensive alternative worked, just tried not to go "cheap". I am attending a workshop in the spring with a professional, I am excited and hoping to really get a lot of good experience and learning. I do better with the hands on experience.

Thanks again!

I do have extenders that I bought to experiment with macro. I LOVE them! I have had so much fun exploring the tiny world in BIG pictures. Have you photographed an ants eyes before? lol
Maybe I could try that.
One thing, what is the significance of the red or white dot, because I did notice that one of my lenses has a white dot.

I do have some Canon lenses. I just took the 35-50mm Canon lens that was on my original Rebel (actual 35mm film camera) and put it on my 6D. I took a couple pictures with it and it seems to be doing fine, no black edges.
Sigma DC 18-250 mm Macro HSM
Bower 35-500mm Fixed Focus Lens with Canon Adapter (I haven't tried this lens out yet on either camera)
Zeikos AF Macro Extension Tube Set (3 pc): I have used this but not with AF as they seem to work best with manual focus.

I should have said mounts to the camera body.

What does that Tamron quote mean in "English"? Why does it shut down my older DSLR Rebel?
This lens is a new model, is what the repair shop said, so my older camera basically isn't "new" enough to work with it. Because they don't service Tamron, they told me to contact the manufacturer to see if it can be modified. (I haven't done this yet).

Wow, OK let's give this a go.

First even though a third party lens maker says their lens work with Canon cameras does not mean it will work with all Canon cameras. Some of them can be re-chipped to work some can't. Some can even have their mount changed to a different brand camera. Some can't.

The red and white dots indicate where the lens mounts because of the different mounts of the lens. You need to be sure you learn the jargon of the lens makers. EF is for Canon full frame cameras like your 6D. EF-S is designed for crop cameras like you old 20D. All lenses will fit your 20D but not all will fit the 6D. Sigma uses DC for FF and DG for crop. Tamron is not so clear so you must read the specs.

You really need to get your optics sorted so you know exactly what you have. At this point I would stop, immediately, using the lens that shuts down the 6D. You can do permanent damage to the camera.

Can you provide a list of your lenses to me? The exact name that is on the lens, I mean? Maybe I can help you decide what works and what don't.

Remember it is always, at least usually, best to stick with Canon brand lenses or any accessory for that matter. Otherwise you need to do your research.

I currently have 40 or 50 lenses in my old darkroom and probably had 150+ over the years. I have some experience with lenses and how well they do or poorly. I can't guarantee I can get you an answer but I might. I usually don't buy or use any of the lesser off-brand third party lenses. They are generally not worth the plastic they are made from.

But even in them there are a few gems.

Like most people I have my favorites but they tend to be quite expensive. There is a fact most people don't realize. A better camera does not equate a better photo. A lot of cameras even share the same sensor for instance. However, a better lens will always improve the photo. Glass is where it's at.

It works on my 6D with black edges. It shuts down the Rebel AND the 6D.
I love the lens, it takes awesome pics. Going to contact Sigma and see if the can do something to help it work on my Rebel. I literally just got this lens a couple months ago, just before getting my new 6D. Because it wouldn't work with my Rebel is why I bought the 6D but I didn't realize the 6D was a full fra

Also shutdown the 20D NOT the 6D

Re: I recently purchased a Canon 6D....

ebiggs1 — Thu, 22 Oct 2015 16:45:03 GMT

Why would Sigma be able to help? Didn't you say it was a Tamron Piiezo Drive 16-300 mm lens?

Whatever, if it were me I would not use it. Shutting down the camera is not a good thing. Something is wrong.

Re: I recently purchased a Canon 6D....

PhotosByNeva — Thu, 22 Oct 2015 23:37:58 GMT

I meant to say Tamron, they may be able to give me more information or modify the lens for me.

If they can, they will want the lens and the camera. And it will take some time before you get it back.

Please buy and use only compatible lenses on your cameras.

Compatibility is important. If you are not sure, use only Canon EF lenses on your 6D. (in the case of your 20D, use both EF and EF-S lenses)

Don't just buy any lenses if you are not sure. Don't buy third part lenses if you are not sure.

Do some researches and start from the very basic. Kit lenses are something not bad. e.g. EF24 105 and EF 24 70 F4. Buy a cheap 17 40 F4 and you have covered from UWA to short tele.

Good luck.

New Tamron and Sigma lenses are very good too but they are not cheap. Some have AF consistency problem and may not be as stable as Canon lenses.
