The APS-C 18-50mm f/2.8 will NOT be equivalent to a FF 24-70mm f/2.8. Sure, the exposures will be the same, but everything you want from the lens will not. First of all the Canon APS-C sensors have a 1.6x crop, so that makes the lens 29-80mm FF equivalent. And since it's actually 18-50mm you will get 18-50mm f/2.8 bokeh. Which will be f/4.5 FF equivalent. So shooting the lens at full tele, you could shoot a FF camera with something like a 70-200mm on it, zoomed at 80mm stopped down to f/4.5, and you would get the same field of view, and the same level of subject to background separation. Which, let's be honest, isn't that impressive. You'd need a APS-C lens with f/1.8 to compete with the FF 2.8 lenses. It's all a bit confusing for new photographers. Rule of thumb: Full Frame cameras let you get greater subject to background separation and less noise in your images at the cost of money, seize and weight.
The 56mm is close to 85mm! Just for APSC cameras, but you can use them on full frame, it just crops in on the sensor, I'm sure this is just the start and next year we will have full frame lenses
Great lenses for the R7.
Definitely I can't wait!
its too late for me. i sold my r7 few months ago. I switched to fuji. and I have this same sigma lenses in my fuji body.
Nice one which Fuji camera did you buy?

Does that mean I can get enough light on a FF camera with a F/4 lens (like 70-200mm) to shoot sports event at a decent level?
😢😢😢 for me those Lens are useless was hoping for 70 to 200m 85mm 100mm 😢😢😭😭😭😭

Way too late. Got into cameras last year and chose Sony because of the lens options
Yeah that's the one thing I didn't realise about when choosing Canon, I don't regret it though
