Thank you for the clarification. I used to buy quite a lot Sigma lenses....but I have been undecided for years until the announcement of 24-70GMII..。

Wildlife in many cases uses primes like 300, 400, 500, 600 and 800mm, it certainly isn’t a make it a break it as it’s normal to have 100mm yes even 200mm between lenses for that field, the same with sports.It is significant, maybe not to you. But to plenty of shooters.Let’s not over exaggerate, yes it’s wider as shown below but it’s not a 20 vs 24mm difference, it’s certainly not big enough that it is a make it or break itShow me a photo taken on the Tamron at 24mm...They look fine, but how would we know from these whether the lens is any better than, say, the Tamron 28-75, which is much, much cheaper?
Fact is, 24mm is a lot wider than 28mm.... Tamron is a great lens if you're willing to make that (not insignificant) compromise to save money.
24mm gives a diagonal field of view of 84 degrees.. 28mm gives a field of view of 75 degrees.
How big of a difference is 9 degrees? How big a difference is 12% in field of view? Well, on the long end, the difference of 9 degrees is like going from 200mm to 600mm. A difference of 12% field if view is like going from 300mm to 350mm.
Would the difference between 300mm and 350mm be important for a wildlife shooter? Might not be a "make or break" difference for some.. but it would be a "make or break" difference for many.
I have not once heard a landscape photographer define that as a make it or break it, there is some who gladly venture out with a 28- to something, I shoot mainly stuff like that and I can guarantee the times I had one over the other didn’t break it, I shot mainly landscape for 6 months with a 28mm lens, just as I have with 24mm and neither of times the lack of one of these has any results in missed opportunities.And the difference between 24mm and 28mm is indeed a make or break difference for many landscape shooters, architecture, etc.
What I also wrote, it gives a slight difference in compression, but it’s not really that big, a different between a 20 and 24 yes that’s quite noticeable or a or a 24 and 35.Which changes the perspective. And there isn't always room to back up. And... you actually need to back up more than just a few steps.and you just need to back off a few steps to get a somewhat similar FV
I owned the 28-75 for a long time. But my ownership of it overlapped owning the 24-105. I found I was NEVER using the 28-75 because I almost always wanted the 24mm. (I ended up selling the 28-75... now that the Sony GM 24-70 is about the same weight as the 24-105, I'm expecting my pre-order delivered this week).

And I can crop a 24mm to become 28mm.. but I can't crop a 28mm to be 24mm...I never seen or heard anyone define a 50mm more or less as such as a break it especially as you can crop.
It is for me. And many others I know. So there, you just heard one.I have not once heard a landscape photographer define that as a make it or break it,And the difference between 24mm and 28mm is indeed a make or break difference for many landscape shooters, architecture, etc.
I've been doing this for 25 years... a bit more than 6 months.there is some who gladly venture out with a 28- to something, I shoot mainly stuff like that and I can guarantee the times I had one over the other didn’t break it, I shot mainly landscape for 6 months with a 28mm lens, just as I have with 24mm and neither of times the lack of one of these has any results in missed opportunities.
It was 6months abroad where shooting was basically what I did other times it was while doing volunteer work , not just going out in your spare time. I’ve been shooting landscape since I was a teenager.And I can crop a 24mm to become 28mm.. but I can't crop a 28mm to be 24mm...I never seen or heard anyone define a 50mm more or less as such as a break it especially as you can crop.

tested my 28 75 Tg2 at the edges for group studio work and its sharp to the very edge its one of the main reasons i bought it as i have to shoot 9 meter wide backdrops and up to 40 dancers at a time.1 test is how each of these lenses perform on an A7RIV at various focal lengths and apertures. I own an RIV and the Sigma Art 24-70mm and I can that for studio portrait work the Sigma has excellent performance but when I do woodland photography its quite poor at the edges of the frame for my liking. My 12-24mm GM does MUCH MUCH better in terms of resolving fine detail.Why should it be. I can't think if there is any perceivable difference in optical quality among these lenses.They look fine, but how would we know from these whether the lens is any better than, say, the Tamron 28-75, which is much, much cheaper?
If I didn't order the GM 2, I may go for Tamron as well.
Guess you don't get my points. If you only carry one lens that I'd agree 24mm is wider than 28mm. But I carry multiple lenses and two bodies into trips, this 24mm has no special magic but just another FL. In my setup, 16-35 GM or 14 GM default on camera 1 (A1) and Tamron 28-75 default on camera 2 (A7r IV), so you see Tamron starts from 28mm has no issue at all but only advantage in less FL overlapping and still much lighter. 16mm is truly much wider than 24mm compared to 24mm vs 28mm. Once I get used to 16mm wide, 24mm is too 'narrow' in many scenesWhy bother with the 28-75… why not just have a bag of primes. You choose a zoom because it offers you a range you find appealing. For some people, 28-75 may be a great range. Others may much prefer having a range of 24-70.The same question show me a photo taken at 16mm from 24-70 zoom ;-)Show me a photo taken on the Tamron at 24mm...They look fine, but how would we know from these whether the lens is any better than, say, the Tamron 28-75, which is much, much cheaper?
That’s what I’m saying 24mm is actually much wider than 28mm. If you want 24mm and 70mm in the same lens, than a 28-75 is inferior to a 24-70. If you don’t care about having 24mm in the same lens, then it doesn’t matter. Different choices, none are right or wrongWe all have different choices.Fact is, 24mm is a lot wider than 28mm.... Tamron is a great lens if you're willing to make that (not insignificant) compromise to save money.
That’s the great thing about the GM2… it’s not much bigger or heavier than the Tamron. 24mm… superior AF and optics, in a body not much bigger.I usually carry two bodies and multiple lenses into trips. To me 24mm is simply not wide nor 70mm or even 105mm is long enough. I also carry 16-35 GM or 14 GM and 100-400 GM together with Tamron 28-75. Therefore such mid-range zoom doesn't have to start at 24mm. Much lighter/smaller/cheaper Tamron 28-75 is much appealing.
I tried the Tamron for landscape and travel, hated it. I found I simply don’t shoot in the 28-35 range. I shoot plenty at 24mm, but hate 28mm. It’s why I switched to full frame, as standard zooms on aps-c were 27-28mm. So I shoot plenty at 24mm… and plenty around 70mm.Sharpness wide Tamron G2 is very close to 24-70 GM II in real-world photos. I use Tamron mainly in landscape photography.
If 28mm is not wide enough hardly 24mm will be. 16mm is truly much wider.

FOR YOU. Not everyone uses that setup.In my setup, 16-35 GM or 14 GM default on camera 1 (A1) and Tamron 28-75 default on camera 2 (A7r IV), so you see Tamron starts from 28mm has no issue at all
16mm isn’t wide enough FOR me. When I want wide, I prefer 11-14. (Gave up 11 when I switched to Sony, so now 12-14). When I want wide/normal, I want 24mm. 28mm is useless to me.but only advantage in less FL overlapping and still much lighter. 16mm is truly much wider than 24mm compared to 24mm vs 28mm. Once I get used to 16mm wide, 24mm is too 'narrow' in many scenes![]()

You like having a range of 28mm to 75mm in one lens, it reduces lens switches for YOU. It’s right for YOU.
Being I DISLIKE 28mm…. 24-70 works a lot better for me. For ME, 28mm is useless. For ME, 24-70 works a lot better.

My simple point that you don’t seem to get — what works for YOU, doesn’t work for ME.
Focal length is definitely a matter of personal preference. There is no good or wrong choice.OKAY! Enough already. Your point is made! None of you guys is going to change the mind of the other. Let’s move on…
???? You can take as many photos as you want with the 28-75.... as long as you want to take photos in the range of 28mm to 75mm.Whatever, pointless.
Yeah you helped me to realize I just cannot take photos from Tamron 28-75 simply because it doesn't start at 24mm ;-)
Exactly what I was trying to say.Focal length is definitely a matter of personal preference. There is no good or wrong choice.OKAY! Enough already. Your point is made! None of you guys is going to change the mind of the other. Let’s move on…
Agreed.I currently own the Tamron 28-75 G2, and it's a great lens, very sharp across the zoom range, fast and accurate AF, nice contrast and colors, etc.
Agreed again. The Tamron definitely isn't crappy. It's an exceptional lens. But I find a need 24mm in a standard zoom, so the Tamron wasn't for me. Lots of exceptional lenses aren't right for me, for a variety of reasons.Not sure why the OP used the word "crappy" when talking about Tamron, they are making some very good lenses these days. The limiting factor is usually the photographer (creativity, technique, etc.)
Visited your flkr and couldn't find 1 24mm image ;-) you even cropped long focal length images to look like panos ;-)???? You can take as many photos as you want with the 28-75.... as long as you want to take photos in the range of 28mm to 75mm.Whatever, pointless.
Yeah you helped me to realize I just cannot take photos from Tamron 28-75 simply because it doesn't start at 24mm ;-)
IF you want to take photos at 24mm, then the Tamron will not serve that purpose.
Different people have different needs. Which is why the Tamron may be the right choice for some people, and the wrong choice for other people. I'm a huge fan of the Tamron but found it wasn't for me, as the range was not useful FOR ME.
There are some, with the 14GM, 20G, 24GM, 12-24, etc.Visited your flkr and couldn't find 1 24mm image ;-) you even cropped long focal length images to look like panos ;-)

Gee, this 24mm FL must have some magic AOV ;-) I know it's a holy-grail to some but just another regular FL to me, nothing special. Really as someone shown you above in AOV comparison, it's not that big difference between 24 and 28mm, but much bigger between 16 and 24mm.IF you want to take photos at 24mm, then the Tamron will not serve that purpose.
Really that difference between 24 and 28mm is so big like day and night, sky and earth? ;-) You are exaggerating totally unproportionally.Different people have different needs.

I’m exaggerating to say that I have different tastes then you? Why do you feel you can force your tastes on others? I don’t judge your preference for 28mm. Please don’t judge my preference for 24mm.What's point then????? You can take as many photos as you want with the 28-75.... as long as you want to take photos in the range of 28mm to 75mm.Whatever, pointless.

You got those reply because you where exaggerating the importance of it in general terms from the beginning , you made it sound like a make it or break it range and you first added the my personal choice later on when someone confronted you with the exaggeration.again, 28-75 works for you. Some very nice photos. Not my tastes, I prefer 24-70… why can’t you accept that different people have tastes?
Why don’t you just shoot everything with a 35mm? 35 is close to 28.. so why bother with a 28-75? I assume it’s because it’s a range you like. I owned the 28-75 for 2 years but found I was never using it, because I did not like being limited to 28 at the wide end. You’re happy with 28mm… good for you. I don’t judge your tastes. Why can’t you accept that I’m much happier with 24mm?
