I'm thinking about upgrading from my current camera (7D, not 7D II) to a 5D mark IV and would like some feedback and information as to whether my existing lens' will work with the 5D IV. First, I shoot mainly landscape and wildlife, but if the opportunity presents itself and piques my interest I'll shoot most anything. Mostly upgrading because my current camera is a little old and I would like to try a full-frame camera, also the newer technology offered by the newer cameras. I like my 7D and it has served me well, but full-frame and upgrading to 30 megapixels interests me. The lens that I will want to use with the new camera are the Tamron 150-600 mm F5-6.3, Canon EFS 17-55 mm F2.8 and the kit lens purchased at the same time I purchased the camera - Tamron o62- 7-300mm F4 - 5.6, Canon EFS 18 -0 135mm and Canon EFS 10-22 mm f 3.5 - 4.5 Any feedback will be appreciated - thanks

Your EF-S lenses cannot be used with an EF-mount full-frame DSLR like an EOS 5DIV. I went from the old 7D to the 5DIII. The differences are initially subtle, but the MP upgrade and the low-light / high-ISO really begin to distinguish themselves when you get into these situations. I've gone back and re-edited work from the 7D, and my various 'knocks' on that camera have lessened over time, but more so as my editing skills have improved.

To put it bluntly: sell all those lenses along with the 7D. Don't look at the little amount they'll fetch, and don't look back period. To cover what you do have, get the kit with the 24-105 f/4L IS II. From there, let you needs dictate what else you need, such as a 100-400L II (wildlife) and / or 16-35 f/4L IS (wide angle).

If you can't handle the both-feet change to FF, look at the EOS 90D that offers upward compatibility with all your existing equipment and the MP upgrade and the continued fps of a sports / wildlife camera.

The Canon EF-S lenses will not work on the 5D, I don't know about the Tamron lenses.

150-600 - YES
EFS 17-55 NO, EF only, EFS will not mount
27-300 - partly (there will be vignetting darkening corners for the wide settings)
18-135 - NO, EF only, EFS will not mount

Canon brand EFS lenses (crop camera lenses) have a tab that prevents proper mounting on full frame cameras. It can cause damage. Other brands do not but vignetting can be a serious loss of image. Cropping by the 1.6 Canon crop factor loses about 60% of the image or uses less than 40% of the pixels. This happens when a crop lens is used on a full frame body because the crop lens projects an image circle too small for the larger sensor.

I can’t comment on the Tamron lenses but unfortunately all of your Canon EFS lenses are specifically for their smaller sensor DSLR’s (like the 7D series), and cannot be mounted to a “full frame” Canon DSLR (1D, 5D, and 6D series).

All the Canon EF lenses will work on either body sensor type; the EFS range lenses are great value for money lenses, but that’s their one restriction.

When I upgraded to the canon 5D mark IV from my EOS 60D a couple of years ago, I found that my old sigma 17-50mm lens wouldn't work well since it only covered an APS size sensor leaving a large dark vignette circle around the images. Although the lens would work I would have to crop the image down to the same as the APS size sensor which kind of defeated the purpose. The other canon lenses I had were designed to work with a full frame sensor and worked great in either camera. I replaced the sigma lens with a canon 24-70mm which works really well. You will need to look up the specs on the lenses you intend to use and they should indicate if the lenses were designed to work with full frame sensors or not. I do like the resolution of the 5D mark IV and it has been a great camera.

Thanks for the "blunt" reply I'd rather get the blunt information, it is a lot more useful. I assume the Tamaron 150 - 600 will not attach to the 5DIV either? I really like that lens for the reach it offers. Thanks again

I'm sure that the UHH members will flood you with great advice on how to spend your $$$.
All of my best wishes with your quest and photographic journey.

I think the Tamron will work. I don't know of any lenses in that focal length range that are design for APS-C sensor. All of the lenses in that focal length range I know are for FF.

As PHRubin earlier said, the Tamron 150-600 should attach OK.

Put a 1.4x III extender behind the 100-400L and you have almost the same reach in a smaller and lighter lens with better image quality in the 500-600 range. It's easy for me / us to spend your money. You also have the entire AF array available on the EOS 5DIV at f/8, something you don't have on the orig 7D.

Thanks, everyone for the quick feedback. I was afraid that most/all of my lens might not work, good to have the information before I pull the trigger on purchasing the 5DIV - revisit the ol checkbook!

You're going to give up the 'reach' of the 1.6 crop factor. If you haven't handled a FF body yet, consider renting for along weekend / week and make sure this is the better direction than maybe the 90D mentioned earlier.

You haven't said why you want the 5DIV. What do you think it will help with?

The 150-600 is a FF lens and will work fine on a 5DIV. I use the G2 version on my 5DIV sometimes and I used a G1 on a 6D before that. If the little you will get for the 7D isn't important keep it so you can use all your lenses. Or sell/trade those lenses and replace wit FF. The main thing you will need is a wide/ultrawide for landscapes as none of your present lenses is a FF wide/ultra wide. You might also want a faster dim light lens. Mine is a 50 F/1.8. And I have a Samyang 14 f/2.8 that covers ultrawide and works well indoors with lights, like in a museum with dioramas. And getting the 5DIV with a 24-105L will take care of a "walk around" lens. I have gone all day at events with just that lens on a FF camera.

As stated the alternate is get a 90D 32 mp (or 80D, still a good 24 mp camera) so you are upgraded, can use all your lenses and get a FF body later. I use a 5DIV, 80D and 7DII. I used to use a 6D and the 7DII. If you want to go FF and still keep the 7D but save a little money look at the 6DII it is a very good camera. When I traded my 6D and got the 5DIV I started to get the 6DII but then I got a check from VA (seems I had been underpaid on my disability for a while) and could afford the 5DIV so I went for it. I also got another 7DII (I had traded it for the 80D for the f/8 focus points-27 vs 1) I missed all the high end AF stuff on the 7DII and found a guy on Ebay whose family didn't want to be bothered with learning the 7DII's pro level features - I got it for $740 with battery grip and 4 batteries. So now I use three bodies - the 80D and Tamron G2 are on a tripod for shots out the door to the feeders in the yard. My 5DIV is used with the 24-105 or macro lens mostly but sometimes the 100-400 mk2 and my 7DII is used with the 100-400L and a pistol grip for my walk around birds, butterflies etc combo.

If I had to get along with only one camera at present I would pick my 5DIV - all of my lenses are FF lenses. I would miss the reach of the 7DII and 80D, but my choice would be the 5DIV. If something happened to all three bodies and I had to buy one body to replace them I would look seriously at the 90D - unless it happened after the 7DIII or its replacement comes out. Then I would try to stretch the budget for that camera. But so far a 7DIII/Replacement (maybe mirrorless) are not even reliable rumors.
