They used to offer a 28-80mm but the only thing that comes close to that is the 24-105mm f/3.5-5.6 IS STM and that's not really a small lens. Is the Sony 28mm f2 a "classic standard zoom lens"? Or a $100 lens for FF? No. Then why do you mention them? Same goes for that 50mm f1.8. Which is not a very popular lens, due to its faults. It is fine for someone to use an old 28-105mm of course, but is that a very popular choice? And not for the pixel peepers, for sure (same goes for that funny little 37-70mm I found). RE: Canon RF 24-240mm f4-6.3 IS USM coming soon - Rover - 07-06-2019 Frankly buying an expensive FF camera and then using rock bottom lenses on it smacks of Luddism to me... At least a little. I'm with Klaus on this one, although I do get curious at times, too. RE: Canon RF 24-240mm f4-6.3 IS USM coming soon - toni-a - 07-07-2019 It's more size than price, Canon 40mmf2.8 pancake is more expensive than 50mmf1.8 and doesn't offer real optical advantages, so why it is selling ? I dpn't always want to carry huge gear, for hiking I am using my Sony A6000 plus 16-50 for size and wight, with a lightweight compact standard zoom like Sony's 28-70 in Canon land I would use my EOS RP instead.

Nor 85mm f1.2. Nor even 35mm f1.8. So, that is your answer. Cameras with lens mounts and separate lenses are not meant as a single lens camera. You can make it be a 24-240mm camera when you want that one day, and a 85mm f1.2 portrait special the next day. And with 240mm f6.3 on FF, you do get shallow DOF (240 / 6.3 = 38mm aperture after all). It is just that, "a convenient super zoom lens". I have never been a superzoom lens customer (never looked at any of the 18-200mm APS-C lenses or any FF equivalent), but I realize that other people might have a want for one.

RE: Canon RF 24-240mm f4-6.3 IS USM coming soon - Rover - 09-06-2019 Vignetting... totally off the scale at the wide end unless the distortion correction is turned on. Looks like what an APS-C lens gives when mounted on APS-H camera outside its comfort zone - not sure if it can be called vignetting at this point, or just "going outside the image circle": https://www.fredmiranda.com/forum/topic/1611970/0#14970167 And I thought the Sony 24-105 was bad in this regard... So let's pack it up and go home - there are no miracles. RE: Canon RF 24-240mm f4-6.3 IS USM coming soon - Brightcolours - 09-06-2019 So they went the Sony/Olympus way, not correcting the wide end to keep the lens simple, and rely on distortion correction in post capture. What you lose by doing this is resolution in the corners. You will get a corrected 24mm FOV image, but not with maximum possible resolution.If I understood JoJu correctly. Nikon also is guilty of under-correcting with the new Z lens line. |
