First, would I buy the RF 24-70 f/2.8 IS. Well, that's a tough one. I love my EF 24-70 II. It's a great lens and works well on the R with my control ring adapter. It's not tack sharp at the edges (not just corners) at some focal lengths - somewhere in the 35mm range - which sometimes requires too much sharpening in some larger group photos.
I've owned both at the same time previously. Image quality is hard to distinguish unless you pixel peep. The RF 24-105 is significantly better than the EF version, which made choosing the 24-70 easier betweenthe EF versions. But as others have mentioned, which one you choose depends on your needs.
Watch on When it comes to a walkaround lens, you generally have two options: a 24-70mm f/2.8 or a 24-105mm f/4 (or something similar). So, which is right for you? Both options have

They are both stellar lenses and I honestly have a hard time to tell the difference of their optical performance. According to lenstip.com, the f/2.8 is slightly sharper at the center and APS-C edge, whereas the f/4 version is slightly sharper at the FF edge at the same apertures.

Hi, I would go with the f/2.8 aperture. Shooting a crop sensor in a dim theater I would really like more than f/4 to work with. Compare the 80d and 60d in high ISO on DXO mark. The improvement is not huge. The 24-70 is by all accounts a beautiful and sharp lens. On a budget you might consider
Costing $999, the Tokina 24-70mm f/2.8 isn’t cheap, but if it offers comparable image quality, it could represent great value compared to such own-brand options as the $1749 Canon EF 24-70mm f/2.8L II USM or the $1797 Nikon 24-70mm f/2.8G ED. We ran the Canon EF version of the Tokina 24-70mm f/2.8 though our industry-standard tests to see how
Tamron’s image stabilization (VC) works exceptionally good. The Tamron had serious vignetting issues at 2.8 (along the whole zoom range). At F4 and above vignetting was no longer an issue. In the center of the frame Canon’s lens is always slightly sharper and at 24mm the edges were significantly sharper than the Tamron SP 24-70mm f/2.8 DI Let's test the new Canon RF 24-70mm F2.8 lens against the EF 24-70mm F2.8 Mark II on two sets of different images. We'll look at images produced using the C has a silent focus motor built into the lens. Sony FE 12-24mm f/2.8 GM. Sony FE 12-24mm f/4 G. Lenses with built-in focus motor focus faster and more quietly than lenses without a focus motor which rely on the camera's body focus motor. minimum focus distance. Lens hood is reversible. Sony FE 24-70mm F2.8 GM. Tamron 28-75mm f/2.8 Di III RXD. The lens hood can screw onto the lens in reverse so that you can keep it on your camera at all times, ready to use. filter size. 82mm. 67mm. This measurement is important to take into account when buying filters.

Canon EF 24-70mm f/2.8L II USM (or perhaps a 16-35 f/4 or the new 24-105 is ii) Canon EF 70-200mm f/2.8L IS II USM; Keep the Canon EF 50mm f/1.4 USM due to f/1.4 which is occationally handy; I like this idea! Might be nice to keep the 100-400, but you could also just use a 2X Extender with the 70-200.

Something like the EF 400mm f/5.6 L USM, or EF 500mm f/4 L IS II USM, or maybe the EF 300mm f/2.8 L IS II combined with a Canon EF 1.4x III or EF 2x III Extender. If you use an extender, you will need a wide aperture lens so your camera will still Auto Focus with the extra stop (1.4x) or two stops (2x) of aperture the extender will cost you.
Also the Canon 24-70 2.8 II is way out of my budget. For the Sigma 24-70 F2.8 has not so good reviews (especially regarding sharpness at 2.8). So I would think that this can be left outside of the 3. What I'm most interested is the comparison between the Canon 24-70 F4 and the Sigma 24-105 F4.
I've found the RF16-35 f/2.8 shows an even bigger improvement wide open in the corners than the 24-70. It's actually a very good astro lens which can't be said of the EF version. I also have the
