Looks like the consensus was right, the 24-105 is the better landscape lens. I might have to pick one up for backpacking to go with my 16-35 GM, plus it'd be a nice one lens solution for just walking around with a small bag. Thanks for doing these!

It looks like vignetting and distortion correction were on for the Sony 24-105? Being on for the 24-105, and off for the Tamron would put the Tamron at a disadvantage. Sometimes you adjust corner samples manually, and sometimes color for the entire frame. Would be better with more consistency. Since you also test lenses without profiles available, it would be nice to see all your lens tests without built in cooking (lens profiles) and no color adjustments. Aren't lens profiles were available for the Tamron 28-75 FE?

They were not compared side-by-side and I just provided the link for reference. I would ignore CA correction for this test and just pay attention to resolution and contrast.

Fantastic test, Fred, thanks for doing all that work!

I'd echo the above request for your impressions regarding how well this lens stands up to the 24-70GM and 24-105G...please

I'm guessing that this post will sell quite a few of these in the coming days lol

At infinity they are very similar at the wide range but starting at 60mm, the 24-105 outperforms the GM, especially towards the corners. I find the GM outstanding from 24-50mm.

Many thanks for all the effort, Fred!

Knowing that you have both the Tamron and the Voigtlander 40mm f/1.2, I'm interested in the differences in colour signature between the two. The 40mm seems to have something special going on, while the Tamron seems more generic (for lack of a better word). Any chance of some tests that would quantify what those differences are? Thanks!

... And the Tamron 28-75 compared to Sony 24-105?

BTW- if anyone is looking for a Tamron, Kenmore Camera has them in-stock right now. No tax and free shipping to me.

I ended up with the Tamron over the 24-105 as I needed f/2.8 for indoor stuff at times, and I think I'll be able to stop-down enough when using for landscapes to compensate for the difference. We'll see.

Awesome test, Fred. Impressive results for the Tamron. This lens is more appealing to me every day.

It would be interesting to compare the bokeh to a few primes to see the difference since you say you're not a fan (maybe comparing primes at both wide open and stopped to f2.8). I could see getting this to replace the Sony 28/2 and 85/1.8 in my kit.

p.2 #9 · p.2 #9 · Tamron 28-75/2.8 FE Infinity test (Resolution & Contrast)

My Tammy arrived today.
Deciding between this and 24-105 has been a really difficult task, but i ended up going with it.
I figured if i am buying a standard zoom it should be as versatile as possible. I thought Sony couldn’t be as versatile as its an outdoor lens and won’t cut it for people. Tammy seems like an outdoor and indoor lens as well as great for people shots.
24-105, while great for landscapes, has this predictable look for people shots, a smaller sensor look i dare say.
Of course i could have done with couple primes and 24-105 but thats the whole point about a do it all zoom. You don’t have to change lenses.
OSS was a big attraction on Sony and i hope Tammy does well with IBIS.
Tammy is inferior build but smaller and thinner. Weight and size was the reason i sold my 24-105 in the first place.
Lets see how things look from here

Didn't make a decision on Tam28-75 vs. 24-105G. I just gave the Tam to the better-half to use on her A7Rii. She's happy and I can borrow it if/when needed.

My Tamron arrived yesterday, had a few minutes to test it out. Love the size/weight of it, feel like it was designed with the size of a mirrorless body in mind (Sigma could learn something from this). Focus is fast, IQ seems good, although I haven't had a chance to test it extensively. So far so good though, I have wider options if I decide I need wider than 28mm.

Respectfully, I have to disagree on the Sony 24-105 not being a people lens. I find this lens exceptional for a f/4 lens for group shots and events, were wider aperture is no asset for DOF. Color and contrast are outstanding and very amenable to PP, at least to my reckoning.

Here are two examples of the dining group I am a member of (sort of potlatch, with rotating hosting), shot at different days and under different lighting conditions and locations.

Based on Fred's terrific tests here, I'm happy I have the 24-105, and when I need faster, I'm confident my Canon 24-70/2.8L II will best the Tamron throughout the aperture range across the frame. Then again, it might be much more economical for some to simply have the decent Tamron 28-75/2.8 if the alternative for all that versatility is passing $3K!

For pictures where you’ll rather shoot at F4 F5.6 yes, could be.

That's usually where I shoot people shots, f/4-8, other than portraits.

I'm really referencing the color rendition, which I find more than acceptable at all apertures for environmental portraits and group shots. The 24-105 has tremendous separation of hues and tones with no muddying or color shift for my purposes.

I had both the Tamron and the 24-105 briefly and went with the Sony. Mainly I liked the extra FL at both ends, but I also found that the Sony with OSS and IBIS (A7rIII) worked very well indoors unless you needed something below f2, at which point primes were called for anyway. I also like the 105 fl for portraits and found that the sony mfd, while greater that Tamron's, actually allowed closer images because it could be used at 105mm. I also found that to get something really sharp on the Tamron you needed to stop it down to F4, and the Sony was great from F4. At f4 and above the IQ was close, except as Fred said, the edges and corners were better on the Sony. I did like the weight of the Tamron; it felt better on the camera.

I actually thought the Tamron was very impressive at center. It matches or surprasses the 40/1.2 resolution-wise at f/2.8. It's well corrected with high contrast as well. My only negative is the astigmatism towards the corners and high contrast and harsh OOF rendering.
On the other hand, the 40/1.2 is very special at f/1.2 + mid-distance and I don't think any other lens can match that look.

I agree, the Sony is extremely good.

So, Fred, considering your opinion on Tammy vs CV40 at f/2.8 and that Mancuso says the Sony 24-105 has better border-corner than CV40 at f/4... could it be said that sharpness wise the zooms are better, either on center or on the corners than the CV 40 until f/5.6?

I got my Tamron 1 month ago from BH after a 6 week delay.

It seems to drive us crazy that these 2 lenses both have their pros and cons to the degree of making it a difficult call as to which to buy. What's easy for us all to celebrate that we Sony fans have such great choices in this category.

I'm also proud of Tamron for making such a character lens.

I bought the Tamron as a utility lens over my primes, for those situations where a zoom was clearly called for.

Far from being just a utility lens, i find the Tamron on my camera a whole lot.

What i like about the lens is close focusing, i.e. 7.5" from the sensor or just outside the external lens element compare to 15 inches for the Sony.

Sharpness in the central area, a stop of light, a bit smaller and a bit lighter. As to bokeh, i like it just fine, dependent on focal length, focus distance as well - you can have it as smooth as you want it or not.
