Future for a Canon T7 and EF lenses?

Tintype_18 — Wed, 22 Oct 2025 12:59:12 GMT

Just a general question here regarding the title. So far, knock on wood, I have had no problems with anything I have in the camera bag or lens bag. I recall someone saying that after a certain date, Canon will no longer offer service on that camera or EF lenses. Not a concern...yet. Your replies are most welcome.

T7 Wasn't listed but I attached a PDF of the EF lenses so you could take a peek.

John,

I'm in the same boat. I have a 90D and EF-S lenses. Only the kit lens I got when I purchased a T7 was purchased new. Other lenses and accessories are refurbished or were purchased used.

I take comfort in the fact that if a lens fails and cannot be repaired, a replacement or upgrade can be purchased used from a reputable re-seller or other source. I also think that there will be a sufficient supply of used EF and EF-S lenses and DSLRs available for the foreseeable future or probably at least as long as I care to use a DSLR and EF/EF-S lenses.

I wouldn't worry about end of service from a financial perspective because you can generally purchase a good used body or lens for less than it costs to repair gear that is near the end of its factory service life.

I have tried to convince myself several times that I need a pair of R1 bodies but every time I try them I realize I prefer the handling of my DSLR bodies. Of course had Canon come out with a 1DX IV that continued to improve sensor low light performance I would have a pair of them now 😂

The time to upgrade/change systems is when your current gear doesn't do what you need for it to do.

EF lenses will have life with an RF converter. I have an EF lens from 1998 that I use on my R8 all the time and it work perfectly. I 85mm EF that is probably 7-8 years old that also is a champ.

I used to be of the "DSLRs are better" then I got a mirrorless and left that "church".

The oldest lens I own is the EF 70-210mm F/4 lens from 1987. Its still working today and fungus free. But it is slow to focus. But when the lens originally came out people weren't worried about the speed. Instead they wanted the camera and lens to focus automatically. When adapted it acquires focus much faster when adapted despite not supporting all of the features. It also gets some IBIS when on a body equipped with it. The lens aperture motor is quite slow. But this is a restriction of Arc Form Drive (AFD) lenses. They cannot carryout AF & aperture control at the same time when the camera is set to Servo AF as newer lenses can. Micro Motor ended up solving all of the problems AFD suffered from. USM lenses never had such restrictions and they date back to 1987. But these lenses weren't the same as newer EF USM with a clutch override for focus. Instead these lenses were Focus-By-Wire like STM and Nano USM lenses. Fun Fact the EF 300mm F/2.8L USM lens was the first Ring Type USM lens released by Canon in November or 1987. This lens was also Focus-By-Wire its a little weird to use focus override because it doesn't work with the camera set to Servo AF. Also lenses released between 1987- August 1991 used Arc Form Drive as the AF motor. Many of these lenses were replaced early on with Ring Type USM or Micro Motor versions. Note some AFD lenses such as the EF 50mm F/2.5 Compact Macro lens would remain in production as late 2022. All AFD lenses were made in 1 factory in Japan and nowhere else. Canon even made 4 L lenses with this AF motor type. Though replacement lenses would feature USM motors instead of AFD due to speed limitations.

Many thanks to all who replied. I have had the T7 for about seven years and added a couple of lenses in addition to the two lenses in the kit. I find it is like my computer, much better than I am capable of doing.

Very old too my friend’s dad still has his copy. The only downside is that there wasn’t IS in 1987. IS would be released in 1995,

Mine is an EF 28-135mm f/3.5-5.6 IS USM and I don't shoot anything that involves action, so it's ok as for focus speed. I love the longevity that is possible with old Canon lenses.

I would adore having an A1 and an F1.

I used to own one of those lenses. It was in production for years before being discontinued. The only documented issue was zoom creep. My dad’s old EOS kit from 1987 still works. It contains an EOS 650 film body, 420EZ speedlite, EF 35-70mm F/3.5-4.5 AFD lens & EF 70-210mm F/4 AFD lens. It all stick works on DSLRs and adapted on Mirrorless. Though there are some limitations on newer cameras. Since the newer features came out later on after the lens was released.
