This makes more sense than a 28-75 for me, if looking for something more compact than a 24-70. I'd rather lose a bit on the tele end and keep the 24mm at the wide end. Especially if paired with a high MP camera, then one can 'zoom' in APS-C mode.

@@danieldevineit would be double in size mate. I reckon it’d be about a kilo or more. The Canon 28-70mm f2 is 1.4kilos (3.15lbs) for a reason. The Tamron 35-150mm f2-2.8 is 1.2 kilos too. F2 is one stop of light more than f2.8, which means doubling of light. Loosely this also means doubling of weight. The 35mm f1.8 is light cause its a prime. The 35mm f1.4 is roughly 1 stop brighter and is double the weight as well. Same goes with 24mm f1.4 gm (450 grams) vs Samyang 24mm f1.8 (220g) or Sony 55mm f1.8 (280g) vs Sony 50mm f1.4 (520g). Point is when you double the light (go up one stop of light) the glass elements roughly double in size as well.

I see it as Sony's answer to make serious APSC shooters jump to full frame as this lens gives Sigma no further reason to even attempt a redesign of the 18-35mm f/1.8. It's a smaller, lighter, and higher quality version of the much loved 28-53mm f/2.8 equivalent lens. Maybe the reason it appears expensive is because there's simply too many other options.

I prefer my 17-28 f2.8 to the 20-40. It has better lens, internal zoom for my gimbal and no CA, no focus breathing. The price is higher which is an indicator with Tamron. I prefer in the future replace my 70-300 with a 50-300 VC half macro and less focusing distance. I can get 42mm in apsc mode from 28mm.

Thanks for this video. I did end up buying this lens. To get other lenses as small and light and cover this range with equivalent image quality I really did not find anything less expensive. A 24mm + 50mm cost as much and don’t travel as a pair at any real weight savings or lower cost if you want to take advantage of Sony features like breathing correction. At least that is what I found. I am pairing this with an A7CR so size/weight do matter. If there is an alternative could you take the time and share that with us. The Sigma 28-70/2.8 DG DN to me comes closest but lacks the field of view at 24mm if you want or need that. Look forward hearing back from you. Take care.

Add to this comparison the fact that this 24-50/2.8 weighs 54g less, is 8mm shorter, and is actually cheaper too, and it looks like quite a good option.

@junhaophua10610 ай бұрын
Hmm, I tend to agree with Chris on this lens. I personally find it hard to recommend it. Perhaps if you are a budding photographer dabbling in someone's wedding, you can't afford the 24-70mm f/2.8, you hate a heavy lens and you must go for a Sony, then yes, maybe this one might be a good start. You will miss some tightly cropped, solo candid portraits though. I can't over-emphasize how important the 60-70mm end is. I travelled last year to the US and it was a pain using my Sony compact camera that could only zoom up to 50mm. I was constantly yearning for just that bit more reach. My composition felt "loose" at 50mm. I also can't recommend the 24-50mm for travel. When you travel, the focal length range should take a higher priority than the aperture size. You will want a longer focal length range than only a one stop increase from say an f/4 lens. The advantage of f/2.8 over f/4 is not significant. (At this point, if you read between the lines, you could guess which Sony zoom lens I would recommend over this 24-50mm! 😃) The "G" label instead of a "GM" is quite telling at 24mm. I don't really like the somewhat blurry rendering at f/2.8-f/5.6. In such a small lens with large aperture, something's got to give. I think Sony sacrificed the image quality at the corners when using the lens at 24mm.

@16-bit-trip510 ай бұрын
He probably feels it's overpriced because of the competition it faces. The Tamron 28-75 2.8 G2 for $900 and the Sigma 24-70 2.8 for $1100 make this a tough sell unless it fits your niche. The price makes sense in Sony's line up but unless the size fits your needs more so than the lack of reach then the value it offers against the competition isn't a no-brainer. If this was a 20-50mm 2.8 then no one would question the price. I think if it were prices at $900 then most people/reviewers would say that's a good price in the competitive space it's in.

24-50mm F 2 could have been the better Option.

This lens for FF is kinda the legendary sigma 18-35 f1.8 for apsc dslr cameras. First, check the zoom range: 24-50 FF and 29-56 FF (or 18-35mm in apsc), And alsoooo 1.8 in apsc is like f2.8 in FF (in terms of bokeh of course, in the amount of light it's a little bit complicated) But here's the thing, Sigma doesn't have that awful distortion in raw, and doesn't have that high price. Ok, that sigma is not for FF, and don't have that aperture ring, but that doesn't justify the price of this weird quality in GMaster Lens.
