No, it does not have the electrical contact. Manual focus is not the issue. Setting the right aperture is. This is the case with the prime lens as well as the 18-55mm kit lens of Canon.


If your extension tubes have no electrical contacts, then you went just a little too low ball.  Those would be useful with a fully manual lens.

 

Most AF, Auto Focusing, lenses have electronic aperture control.  Without the electrical contacts, there is no way you will get aperture control with an AF lens.  

 

Macro lenses can also double as very good prime lenses.  In addition, because of their flatter focus plane, they can be useful where standard lenses are not.  For example, I recently too photos of a fairly wide wall mural.  The left and right ends of the mural were falling out of focus due to DOF.  My 100mm Macro was able to capture all of it in focus.

Re: T7i - Beginner macro photography challenges

Thanks for all your valuable suggestions. I think the best way for me to test this is to rent the lens for a day or two and try out if the macro lens works for me.

Re: T7i - Beginner macro photography challenges

Now you'er talking.  Even if you got the cobbled off brand stuff to work the results would likely not be high quality.  So then the question becomes why do it at all.

Another lens choice that has not gotten any mention, probably because of the focal length, is the EF-S 35mm f/2.8 IS STM Macro lens.  It has 1:1 magnification, and an MFD around 5 inches.  It would probably also be a pretty good “normal” lens on an AOS-C sensor body, too.

Re: T7i - Beginner macro photography challenges

I have always felt that that lens has too small a working distance for 1:1.

The EF-S 35mm f/2.8 Macro IS STM is an interesting lens but I would still go for the EF-S 60mm f/2.8 Macro USM instead.

I agree, but ...

 

If you are shooting static subjects, the distance should not be an issue most of the time.  If you need to back up, the camera has enough resolution to where a modest crop should not make much difference.  Also, the shorter focal length should give you more DOF.
