I just don't generally do that type of shooting....and there is no sun now and it doesn't look like there will be all weekend. It's dark, gray and windy now.
Maybe someone else will give it a go.

No worries.
Also, re our recent discussions: I found that a Kase 150mm magnetic ND was flat, and a perfect match for Nisi 150mm PL, unlike the Haida you tested for me.

Hi Tim, and others,
I've been researching this lens as I'm in need of a 'walk about' lens. Most reviews I've watched or read are very complimentary, saying that the G2 lens is sharper than the G1. When I look at tests over at The Digital Picture (I'm not a 'pixel peeper' but I do prefer objective tests as opposed to 'real-world' tests) I see some very concerning results. The G2 has very poor CA, and pretty poor vignetting (nearly 2 stops). I understand that this is removed in post, but making this correction means the IQ out at the image edges will decline. This poor performance is really noticeable at the long end.
Is it possible that Bryan over at T.D.P. got a lemon? I do quite a lot of architectural and urban landscape photography (as opposed to nature landscapes) so getting very good quality at the periphery is important.
I did a search for tests/reviews here but didn't come up with anything. If I've missed it, or I'm rehashing a conversation already had, I apologize. Just point me over there. :-)

Mine is definitely weaker at 75 and has more CA there as well. But through most of its range it’s excellent, including the periphery. I have quite a few lenses that vignette a decent amount, I guess I’m sort of used to it.
I’m still more a prime guy at heart and I have my Pentax 28, CV 35/50 APOs and Pentax 77 for landscape shooting.
Maybe over time more reviews and comparisons will be posted.

I did some limited comparisons of the G2 to the G1, 24-105G and 24-70 DN. I recieved a flawed copy of the G2. I have since returned it for an exchange, but am still waiting on the replacement as it is out of stock at B&H.
I only have a single copy of each, so copy variation may be important relative to overall design. Even with a flawed copy of the G2 the sharpness (for the part that was not flawed) was similar to the 24-70DN and significantly better than the 24-105G, my 24-105 was sharper at all focal lengths and aperatures compared to the G1. So I would say the G2 is significantly sharper than the G1. This matches what I have seen in pretty much all reviews.
My impression is most modern high IQ lenses do pretty good on CA. It's not something I typically worry about, I don't typically notice it in my photos. I can't say much about the G2 in this regard.
My thought about the vignette was the oposite of yours, I heard people say how good the G2 does in this regard. I would recomend you compare this lens to other 24-70, 28-70, 24-105 on TDP. Taking a look at this: the 24-70GM significantly beats the G2 on vignetting, The G2 and 24-70 DN are similar. The G2 significantly beats the 28-70 DN and 24-105G (G2 compared to 24-105 at f/4). Comparing to GM primes at f/2.8 it is similar to the 24GM and 50GM, better than the 35GM (vignetting is my only complaint on the 35GM), and worse than the 85GM. The design clearly counts on computational photography to fix this area. The amount of vignetting seems reasonable, I assume this will be a tradeoff against size and weight. Since sony has this built in, the end result is you loose 2 stops of dynamic range in the corners. I don't have enough personal experience for my own opinoin on the G2, it is based on TDP data. But thank you for asking this question, I don't think I would care for the vignette on the 28-70DN. I found the vignette acceptable on the 24GM, so I don't think I would have any issues with the G2.

The CA one sees in the TDP test is surprisingly bad. This may be due to being a flawed lens, like yours. I haven't heard/read any reviews mention the QC at Tamron ... seems like a good topic to investigate.

Well, I don't think there will be a dedicated review thread for this lens.....so I'm putting this here, hopefully people won't mind.
Here are some comparisons between the Tamron and the Sony 24-105 on my Sony a7R III.
All these shots were taken on a tripod, processed via Lightroom, with vignetting correction on by distortion correction off. I did enable chromatic aberration correction.
This are at f/5.6, not sure if people want to see other apertures.

Tim, That looks good. I would be interested in wide open as well. I have been thinking about where around me I could do consistent photos at infinity with enough detail. Looks like your choice of Hershey was good. Has the park opened up from Covid yet? I look forward to taking a detailed look at these. I finally had a combination of sun and availability to shoot brick walls with the 24-70DN yesterday. Still waiting on the replacement 28-75G2.
My Grandma used to live a bit north of there in Lykens.
PS: I had a chance to download and open the big files, looks like lots of detail on both lenses. Only wide open photos if you happened to take them already.
Edit: Thoughts on comparison
28mm - to me they look almost identical, green building upper right looks a touch better on 24-105, some of the forground vegitation better on 24-105. I would rate identical
35mm - 24-105 seems a bit better in upper right, but worse in lower left. I still see a bit better forground vegitation in 24-105. Rollercoasters are running, park is open. I can see a couple differences but they are still very similar, I would be happy with either, I would rate the same.
50mm - G2 is stronger especially in lower left, foreground vegitation looks beter to me on G2. I would give this to the G2.
75mm - G2 is stronger on left side, see stone wall in building. 24-105 is a bit better on right side. I would slightly give this to the G2 as well.
Overall I would be happy with either lens. I think in actual use both lenses are resolution limited more by the camera than any major difference except at 50mm the 24-105 is a bit weaker.
This matches my 24-105 as well. Mine is weaker at 50mm and wide open at 105mm, best at 28mm and 85mm. I have attached some data from my brick wall testing of my 24-105 lens. Purple is best, blue is above average, green is average, yellow, orange and red are bellow average. Colors are based on comparing all the lenses in my collection.

Unfortunately it's tough to find a day on the weekend (when I'm not doing something else) where it's sunny and not hazy. For whatever reason, it often is cloudy this time of year, and there is a haze close to the ground. But since Hershey is so close, I can steal away when I think conditions might be right. (They weren't great today, but better than other days I had some time.)
Lykens isn't too far away, just over the mountain, definitely a small world.
Hershey Park was open this year, they just do a smaller area with holiday themes after the park closes for the summer.
You want f/4 from both lenses, or just f/2.8 from the Tamron?

If you didn't capture wide open at the sime time, I wouldn't bother with it. I like to open the files in fastone image view to compare, you can do a side by side comparison of multiple photos (p button after selecting files). On a different day I suspect the light would be different (not really comparable photos) and hard to say how much stopping down helps.
I edited my prior post with my thoughts.
What are your thoughts and your plans for the 24-105 and G2? For me I wanted a faster zoom for use indoors and if it beats the 24-105G at other apperatures that would be a bonus as well. I like the lighter weight of the G2 vs the 24-105. For walkaround I like the extra focal length of the 24-105.
p.2 #13 · Tamron 28-75mm f/2.8 Di III VXD G2 A063 - Image & Sample Thread
I have 28, 35, 50, 75 from wide open to f/16 from both the Tamron and the Sony. I also have the same at 35 and 50 for the Tamron and CV APOs.
I use Photo Mechanic and can do similar, actually was doing that as we speak.
So your wish is my command. You want just the Tamron at f/2.8? Both the Tamron and Sony at f/4....all of the above?

Tim,
If you have the 35 and 50 APO at 5.6 that would satisfy me.
I was surprised how close the 24-105 and G2 were, at lease to my middle aged eyes.

Wow, this is very generous of you, Tim.
To my eyes (I'm looking on a 2015 macbook pro, too) the Tamron and Sony are comparable, maybe an edge to the Tamron. Seems to me the Tamron is a little sharper in the bottom left.
The Voigtlander appears sharper across the board, but that's not surprising given the nature of the lenses.
I haven't compared the correct Tamron to the non-corrected ... next. I'm curious about the CA corrected & non.
