Crop the Tamron at 180mm a little and your image will be sharper and more detailed than the Sony at 200 mm. 180 vs 200mm is so minimal difference. There is good YouTube videos on Tammy 180mm vs Sony 200mm. I'd take a 70-180mm at f/2.8 all day over a 70-200mm at f4. Wow, never knew its a bad lens, let alone one of the worse. The Tammy it is!
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

Has rounded aperture blades. Sony FE 24-105mm f/4 G OSS. Tamron 17-70mm f/2.8 Di III-A VC RXD. Similar to the number of aperture blades, rounded blades affect the way the light gets through to the sensor. Rounded blades, often only found on more expensive lenses, improve the appearance of the out-of-focus areas.

My 70-200mm f/4 is a heck of a lot lighter. As for the optics, the 17-55mm does have very good optics, but the 24-70mm clearly outperforms it both wide open (f/2.8) and the sharpness covers more of the frame, with sharpness dropping off 15mm from the centre of the image, whereas the 17-55mm starts dropping sharpness immediately.

This lens has recently been replaced by Canon's new 24-70mm f/2.8 USM 'L' Mark ii - and so now you can find the original for a much more reasonable price. It
At the wide angle end of the zooms (both tested at 28mm), the Tamron was slightly sharper in the center at f/2.8 – f/4 but the Sony was sharper away from the center and towards the borders of the frame. However, at the other end of the zoom, the Tamron had significantly higher resolution and was generally sharper across the frame.

I've wanted to see the Canon RF 70-200mm F4 L IS USM Lens beside the Canon RF 70-200mm F2.8 L IS USM Lens, so I got around to creating a mockup today.. While both of these lenses are considerably smaller than their EF counterparts, the RF f/4 lens is considerably smaller (and lighter) than the RF f/2.8 version.
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
I'm sorry for another f/2.8 vs f/4 thread, but I couldn't find some answers in the existing ones. I have R62 and R7 with RF 24-70 f/2.8, EF 70-200 f/4L and EF 100-400 L IS II. I shoot animals, airplanes and standard photos (family, trips, etc.) I love my EF 70-200 f/4L, but I didn't use it much since I got 100-400 and that's because of lack of IS. 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 .
