Canon RF 70-200mm f4 v f2.8


So, you like me have bought your RP, R, R6 or if you are very rich the R5 Canon body and are now scratching around for your RF lenses.

If you have the R5 then you probably already have bought most of the current RF lens line and this post is probably not for you 🙂

For the rest of us what is the real difference between the Canon RF 70-200mm f4 and the f2.8?

Well the obvious is one stop of light between f2.8 and f4 but is that it for a f2.8 lens that costs nearly £1000 more than the f4?

Here is who they compare side by side.

77mm filter threads, 9 blade apertures, Minimum apertures of f32 which is brilliant for both, 5 stops of Image stabilization.

The f4 is lighter at 695g compared to 1070g

The f4 is shorter at 1193mm compared to 1460mm

The f4 can shoot 10cm closer to your subject at 60cm rather than the f2.8 at 70cm.

the f2.8 has 1 more element at 17 compared to 16 and 2 extra groups (13) compared to the f4’s 11.

They both also have Canon’s Dual Nano USM for smooth, fast and near silent continuous focusing

Both are dust and water resistant

Both have the awesome Canon RF lens control ring

So which one should you buy?

Well, as I joked in the beginning about R5 owners, if you own an R5 you probably already bought the Canon RF 70-200mm F2.8L IS USM.

But if you are a mere mortal like me then if 1 stop of light, an extra lens element and 2 groups means a lot to you then spend the extra £1000.

For me the Canon RF 70-200mm F4L IS USM will do all I perceive I will need it to and if it is like its RF 24-105mm f4 cousin I bought recently, then I already know you and I will not be disappointed with the Canon RF 70-200mm F4L IS USM and we can put the £1000 towards the RF 85mm f2 lens lol.

Note: I am not affiated with Canon or any other company and my opinion expressed here is my own.
