Sony FE 70-300mm f/4.5-5.6 G vs Tamron 70-180mm f/2.8

Hello ! Sorry for the translation errors, I am French.

I have had the 70-300mm f / 4.5-5.6 from Sony for 2 years. I took my best photos with it.
But recently, I wanted to increase the image quality by switching to a 70-180 f2.8.
Especially since I mainly do portait.
Reading reviews on the internet, people seemed to spit on the Sony with its small aperture, and especially its price of € 1,500 new. (luckily I got it for 800 €)
Either ... I decide to buy the Tamron of which I read the praise everywhere on the forums, 950 € on occasion.
I spent 1 month testing the two lenses to compare them.

Unsurprisingly, with the Tamron I reduce the ISO mount thanks to a shorter depth of field, but I still lose 120mm of focal length that I used a lot.
The problem is that apart from setting the aperture and its lower ISO, it's not a revolution. I thought I was going to break free from a technical limit, but no.
I have the impression that 900 € + loss of 120mm of focal length is not worth it compared to the gains in image quality.
So I'm thinking of reselling the Tamron for € 915, instead of selling the Sony for € 600.
I hesitate because I don't know if I manage to judge my images properly.
I'm still a hobbyist and when I hear that the Tamron crushes the Sony, I think maybe it's me who is wrong.
We can sum it up with a question:
What more can Tamron give me that I couldn't do with Sony?

I give you access to some test photos which compare the two lenses:

TEXTE D'ORIGINE :

Bonjour !

Je possède depuis 2 ans le 70-300mm f/4.5-5.6 de chez Sony. J'ai fait mes plus belles photos avec.
Mais depuis peu, j'ai eu envie de monter un qualité d'image en passant sur un 70-180 f2.8.
Surtout que je fait principalement du portait.
En lisant des avis sur internet, les gens avaient l'air de cracher sur le Sony avec sa petite ouverture, et surtout son prix à 1500€ neuf. (heureusement je l'ai eu à 800€)
Soit... je décide d'acheter le Tamron dont je lis les éloges partout sur les forums, 950€ en occasion.
J'ai passé 1 mois a tester les deux objectif pour les comparer.

Sans surprise, avec le Tamron je diminue la monté en iso grâce à une profondeur de champ plus courte, mais je perds quand même 120mm de focal que utilisais beaucoup.
Le problème c'est que hors mis l'ouverture et son iso plus bas, ce n'est pas une révolution. Je croyais que j'allais m'affranchir d'une limite technique, mais non.
J'ai l'impression que 900€ + perte de 120mm de focal ne vaut pas le coup par rapport aux gains de qualité d'image.
Je pense donc à revendre le Tamron 915€, au lieu de vendre le Sony pour 600€.
J'hésite car je ne sais pas si j'arrive à juger convenablement mes images.
Je suis encore amateur et quand j'entends que le Tamron écrase le Sony, je me dis que c'est peut-être moi qui fait erreur.
On peut résumer les choses par une question :
Qu'est-ce que le Tamron m'apporte de plus que je ne pouvais pas faire avec le Sony ?

Je vous donne accès à quelques photos test qui comparent les deux objectifs :

Comme ça vous pourrez juger vous même.

Merci d'avance !

Use the lens that you like. Fun and usability is what is what makes you take pictures, not technical specs.

You want to use the telezoom mostly for portraits, but you want those missing 120mm anyway. Why? Classic portrait range is 85 - 135mm, which is covered by Tamron. Makes not much sense from your post to me honestly.

What more can Tamron give me that I couldn't do with Sony?

Better microcontrast, better bokeh, shallower DOF when wanted, better sharpness.

If you really miss the 120mm difference, you could look at the Tamron 70-300: compared to the Sony, it's lighter, smaller, has better contrast and at least as good sharpness. Even though it doesn't have lens OIS, I found that it gave sharp and nice looking images more often than the Sony.

The 70-180 2.8 is in a higher category for rendering, but I often happily use the Tamron 70-300 for travelling and hiking. The Sony 70-300 is sold and not missed...

I also sold my Sony 70-300mm several years ago and do not miss it one bit.  It was marginally sharp for the 42mp I was shooting at the time, was one of the least-contrasty lenses I have shot on Sony bodies (yielding lackluster images), and the autofocus was relatively slow when shooting action.  The Tamron 70-180mm would be a major step-up... even if 180mm was cropped, IMHO.

I have the Sony 70-300 which I bought used for the simple purpose of having a light lens that length not expecting much out of it.  I find that at least my copy is very good and when used outside it is truly underrated by many.  I used Tamron lenses quite a bit in the "A" mount days and have no issues with them, but if what you are after is in the center of the lens the 70-300 is not that bad at all.

Lenses are funny at times.   I have several GM lenses and many times when reviewing images from a day of shooting I see one or two that really stand out and more times than not I look at the metadata and that darned 24-105 G shows up.

You are asking a question that truthfully; you are the only one that can answer.   No one suffers at times from GAS more than I, but don't discount what has given you pleasing results in the past.

Oh.....I have a number of bird feeders just outside my kitchen window and while I have a 200-600 to use, I keep the 70-300 on either my A7riv or A1 at all times in the event an unusual bird pops up and with that 300 reach plus APS C mode and placing the bird in the center I get good results.   Here is a recent example taken through a double paned window in deep shade.

Hello.
While using 70-180 lens have you met the behaviour I described in the neighbouring thread here.

I would love to have your experience shared.
