20-70 f4 questions
p.2 #120-70 f4 questions
I like the lens a lot. These are taken on my A7Cii, the first two at 20mm and the last one at around 45mm, all these at f7.1. I actually added vignette to these images. These are from the historic South Bay Area shrimping town of Alviso, CA -- it's where I generally head to test out new gear.
PS: I haven't used ACR for a long, long time to convert images. But I got tired of paying for both C1 and Adobe Photo subscriptions, so wanted to see if I could live with ACR. So far, I'm not overly impressed and may in fact bite the bullet and revert to C1.

It’s a great lens perfect for backpacking and I love mine. My copy is the first and only one I purchased brand new from B&H and it’s tack sharp edge to edge at f/8 and f/11 which are generally the apertures I use for landscapes. It’s lightweight and easy to carry. I use mine often with the A7CR and find it balances well. Sometimes I’ll pair it with a Batis 135 for something telephoto or even pair it with the Tamron 28-200.

Curious how the Sony 20-70 compares to the Tamron 25-200; I have the 20-70 and Sigma 20-200 and am thinking of selling the latter as it sometimes mis focuses and has gaps in sharpness.
In terms of the 20-70G - like others on the thread, I've only ever had one copy and it's been well sharp enough for me. Photos specifically using this lens can be found here:

I do not have the newer 25-200 and have the older Tamron 28-200 and I can say it's very sharp and very comparable to the 20-70 f/4 G throughout the whole 28-200 zoom range. That's one reason I like pairing those two lenses together because the image quality is quite good and consistent from 20-200 plus the Tamron is also a f/2.8 at 28mm. I've even been able to shoot astrophotography while out in the backcountry with the Tamron and having only those two lenses with me. I know these two lenses overlap each other quite a bit but I essentially use the 20-70 mostly, and consider the Tamron as my "70-200" that can go wider when needed. This combo helps me from swapping lenses all the time.

Lots of overlap between those two lenses but that zoom combo works well and covers 20-200 and not too heavy really. Another combo I will use for backpacking or long hikes is Tamron 28-200 + 20mm f/1.8 G especially if I’m doing any astrophotography. I just recently got the Viltrox 14mm Air and I may pair the Tamron with that too depending on where I’m going. But If I were just bringing one lens though it would be the 20-70 for certain. It also makes for a great skiing lens too.In terms of the 20-70G - like others on the thread, I've only ever had one copy and it's been well sharp enough for me.

My 25-200 was not as sharp as my 20-70, especially on the long end closer to 200mm (which I realize is more than double the 20-70 reach). A bit softer on the wide end too, but I only noticed it when cropping a lot. Ultimately I sold the 25-200 as it felt a step backwards from the 28-200 I used to own and wasn't sharp enough to replace my 20-70. Again, this is only with my copy of the 25-200, seems there's a bit of copy variation on this lens I've been noticing.

I have been taking out my 20-200 quite a lot these days trying to convince myself it can replace the 20-70 (and potentially the 50-300); but for now it just cannot. That being said, I got some very nice shots with this lens:
