Canon RF 75-300mm f/4-5.6 Coming Shortly

[Canon Rumors]

It looks like Canon has announced an RF 75-300mm f/4-5.6 lens, but it isn't being announced in the USA for the moment. This is obviously a surprise to us, but we don't get a lot of information about entry level lenses ahead of time, and that's cool.

The EF 75-300mm was probably the worst lens that Canon even made for the EF mount, so hopefully the RF version is better. We’re confident that Canon will make a better lens with the RF mount version.

The RF version is the EF Mark III lens with an adapter glued on.

The specs are exactly the same, and it even has the ol' DC micromotor AF. The length of the lens grew by exactly the difference between the EF mount and the RF mount.

Pairing this with like a 17 - 75mm on crop sensor would be far more useful to me than the current situation, which pairs a teeny ultrawide zoom with a big superzoom.

That's awful, what an terrible lens that was.

Truly astounding innovation from Canon. Bold and intrepid. What other major brand has the vision and dedication to glue a mount adapter on a cheap lens that's a quarter-century old and call it new. Ok, in fairness although the lens is from 1999, they did add the super spectra coating that was first seen on the 24/1.4L II in 2008. Yay. So...Canon FTW?

Oops, I was wrong above, although I will blame Google's AI summary, which suggested that super spectra coating (SSC) was first used on the EF 24L II when more digging showed me that Google was confusing it with sub-wavelength coating (SWC). SSC was used on FD lenses. So it really is the same old EF MkIII. Go Canon!

This lens is doomed!

I mean I think this lens will probably sell loads, like the EF 75-300s before it.

DC certainly stands for Direct Current, a very inexpensive type of electric motor. Also used in cheap power tools.

You could certainly be right. Price in Europe is said to be around Euro 300 before the expected discounts...

The EF 75-300 III was about 2/3 the cost of the EF-S 55-250. The RF version of that lens costs more and only goes to 210mm. There's definitely going to be a market for a RFcycled™, cheap 75-300mm. Bonus that it 'works on FF' so buyers see an upgrade path.

Why? RF100-400 is pretty much invincible, and the EF 70-300 USM II is likely to be better than this lens.....

"The EF 75-300mm was probably the worst lens that Canon even made for the EF mount..."

Nah, the EF 28-200 3.5-5.6 was absolutely horribobble. Can't imagine the 75-300 was worse than that one ;-)

RF 100-400 lists for $650 / 670 €. The RF 75-300 will likely be less than half of that. That's why.

I really don‘t know what to think about this Lens.

Reviews and IQ comparisons will tell, if this is something worth thinking about.
Or if it will be like the old EF

First German prices:

RF 75-300mm F4-5.6 326,99 €

Looks like hands off

It is the old EF. Literally the same lens.

 

[AJ]

They should reissue the old 28-80 kit lens

Anyways, there are a gazillion used 75-300s out there on the used market. It'd be cheaper to get one of those and to use a 3rd party EF-RF adapter.
Then again, I bet this lens is going to be packaged with camera bodies. I doubt if they'll sell many after market.

 

[blackcoffee17]

Well, at least it\'s not 7.1...

 

[blackcoffee17]

Because $500-600 is a lot of money in many parts of the world.

At least the RF 400 2.8 and 600 4 were copies of very good important EF lenses.
This one... ^5 (it's called "cautious" emoji, but for me it is totally a "side eye" emoji )

So in the same day we get a fuzzy but exciting rumor, and this pile of
Perfect pair with the R100?

I know it will probably sell a lot of units... but thank you Canon, more savings for me... (technically cost avoidance I know)
