Tableau comparatif des performances d'optique pour les distances focales et ouvertures de l'objectif Sigma 20-200mm.
  • The wide end is the best focal length for centre performance , but corners one was a bit disappointing on my sample
  • between 50-100mm we get very good results but not excellent
  • 200mm is weaker wide open : only good and benefit to be close down to F8
  • Overall a very good performance for such a superzoom

  • La position grand angle est la mieelure pour le piqué au centre, mais le piqué dans les coins décrit un peu
  • entre 50 et 100mm c’est très bon
  • 200mm est un peu plus faible à pleine ouverture et on gagnera à fermer à F8
  • Une très bonne performance pour un superzoom

From a specifications perspective price and weight are quite similar. The main competition is between the Sigma that start at 20mm vs 25mm for the new Tamron but the Sigma is one stop slower.

In practice the possibility to have ultra wide between 20mm and 25mm is for me more important than gaining one stop.

Also the Sigma has a real 0,5X magnification between 28-85mm whereas the Tarmon has it only at 28mm

D’un point de vue spécifications, le poids et les prix sont assez similaires tout comme l’ergonomie. La différence clé entre le Tamron 25-200mm et le Sigma 20-200mm est la plage 20-25mm du Sigma qui apporte un énorme plus en voyage, plus pour moi que un stop de mieux sur la plage focale

4.7 Conclusion

The Sigma 20-200mm offers a unique range very useful for travel. The difference between 20 and 25mm is very significant for a travel zoom. On top sharpness achieved is superior to the Tamron 25-200mm and Tamron 28-200mm F2.8-F5.6 Di III RX. The Tamron however have a better aperture

Le Sigma 20-200mm offre une plage focale unique pour un zoom de voyage. La différence entre 20 et 25mm est très importante en termes de possibilités. De plus le piqué est supérieur aux autres zoom comme le Tamron 25-200mm et le Tamron 28-200mm F2.8-F5.6 Di III RX. Les Tamron ont néanmoins une meilleure ouverture

6 Conclusion

The Tamron 25-200mm F2.8-5.6 (850 euros) is the new version of the Tamron 28-200mm F2.8-F5.6 Di III RXD, adding 3 precious mm on the wide end. Overall it is a very convenient lens with very good results globally in term of sharpness, AF , bokeh for such a travel zoom but it lack a real proxy photography capability

The main competitor is the Sigma 20-200mm F3.5-6.3 DG Contemporary (900 euros) which although 1 stop slower, provide a better range and better sharpness and real proxy macro capabilities

Recommended if you give the priority to the aperture over the zoom range and sharpness

    Bonjour,

    En termes de comparaison de netteté, un test sur mire disponible sur the-digital-picture.com raconte une toute autre histoire que la votre, tout comme la revue de Dustin Abbott !

    https://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=1755&Camera=1538&Sample=0&FLI=0&API=3&LensComp=1746&CameraComp=1538&SampleComp=0&FLIComp=0&APIComp=2

    “The Sigma 20-200mm simply tries to do too much and, I believe, suffers for it. I appreciate the extra bit of width on the 25-200mm VXD, and, while it isn’t penalty free, I think that the compromises to get that extra 3mm on the wide end are more palatable.”

    J’ai pris le Tamron car les coins du Sigma sont beaucoup trop faibles à mon goût sur les focales larges et intermédiaires 😉

    Cordialement

        Du coup, comment faites-vous pour parvenir à un avis aussi tranché que
        “Le Sigma est de loin le meilleur des superzoom” 🙂 LOL

        Marc Alhadeff

        La cible pour ces superzooms est ceux qui ont des capteur 24-33mpix pas les boîtiers pro de 50-61mpix
        Sur 33 mpix les différence de piqués seront négligeables entre un excellent et un très bon exemplaire et peu différente entre sigma et tamron
        C’est donc les autres critères qui sont plus important comme la plage focale et la proxyphotogrpahie ou le sigma l’emporte
        Le seul point ou le tamron est meilleur est l’ouverture
        D’où ma conclusion si l’ouverture est le critère le plus important prenez le tamron sinon le sigma

    Marc Alhadeff, thank you so much for your review of the lens. It’s a shame the sharpness didn’t live up to expectations. I was hoping for a big improvement over the Tamron 28-200. Also, given its shorter focal length range than the Sigma 20-200, I was hoping for better sharpness, but it wasn’t meant to be. I’ll probably buy the Sigma 20-200 to replace the Sony 20-70 for more travel versatility.

      Seems there are quite some variability I got a excellent sigma and average tamron form the shop
      So bottom line buy where you can return the lens to be sure you have a good copy

      Hi Roman,

      There seems to be a lot of copy variations on both these zooms…on the links below you will find completely opposite results/conclusions:

      The best option is to get one, test it and to return it if not happy.

        It’s probably a matter of luck. Samples can vary from one another. The question is, how much is this deviation? To answer that, we need to test a sample of lenses, not just one, but that’s difficult.

    Bonjour,
    J’apprécie votre travail et la base de données incomparable que constitue vos test. Je pense néanmoins que sur cet article une relecture s’impose. Vous inversez le sigma et le tamron dans l’article… ouverture, plage focale etc…
    Courage il en va de la qualité de votre revue 😉

    Bonjour Marc,
    J’étais prêt à acheter cet objectif, je n’attendais plus que votre test pour valider. Je ne m’attendais pas à une telle conclusion, à vous lire le 28-200 est meilleur… Du coup j’envisage de partir sur un 24-105 d’occasion, qu’en pensez-vous ? (sur un A7 4). Bonne continuation.

      Sur un a74 de 33mpix ces différences entre v1 v2 ou sigma seront négligeables
      Du coup choisissez surtout en fonction du critère le plus important pour vous plage focale et proxy photographie (sigma) ou meilleure ouverture (tamron 25-200)

    Hi Marc:
    Definitely the variation of this copy as my friends one. His copy was the same issue on 200mm which could not focus well. He returned and exchanged an copy and it has totally different result at 200mm.

    My 25-200 is MUCH sharper than my (now sold) 28-200 at 200mm. Both sharper and less hazy (better contrast). Not sure if I have an unusually good copy of the 25-200 or if my old 28-200 was unusually bad, but I find it to be a big upgrade, optically, and I love it.

    The Sigma lenses I’ve tested, on both Sony and Fuji, have given me subtle but weird cyan/green-ish color casts on snow and white walls. A bit like the difference in white balance between the Tamron and Sigma photos of the LEGO guy above, but consistently when there are bright whites like snow and I shoot the same scene with both Sigma and any other brand lens (Sony, Tamron, Samyang, Viltrox. Fuji). I no longer bother even trying Sigma lenses because of this.

    Bonjour,

    D’abord merci pour tous les tests et le super travail que vous faites 🙂

    Je suis photographe amateur, j’ai un Sony A7III. J’ai eu le 24-240 pour débuter, mais celui ci ne me satisfait plus en terme de qualité optique.
    Je photographie principalement des paysages et de l’animalier quand l’occasion se présente, et quelques fois un peu de portrait.
    J’ai vendu mon 24-240, et n’ai pas un très gros budget pour un nouvel objectif.
    Je souhaite partir sur un modèle polyvalent, et ai donc dans ma short list, le Sony 24-105, le Sigma 20-200 et le Tamron 25-200.
    Le 24-105 paraît encore très bon en terme de piqué et de qualité optique, et sera le plus lumineux.
    Est ce qu’il y a une grosse différence de piqué entre celui ci et les 2 autres, du moins une différence qui expliquerai de partir sur cette objectif qui est moins polyvalent ?
    Ou la différence est minime et dans ce cas autant partir sur le Sigma ou le Tamron.

    Merci d’avance si vous me répondez 🙂
    Bonne soirée,
    Romain

    Salut, merci beaucoup pour tes tests, une vraie mine d’or !
    Question, entre le Tamron 25 – 200 et le Sony 20 – 70, tu conseillerais lequel pour de la photo de tous les jours / voyages / randos / treks en montagne ?
    J’ai un A7 33Mpix et surement un futur a7cr d’ici 2 ans.
    Je n’ai pas l’habitude du grand angle donc je me dis Sony 20 70 mais le range 70 – 200 m’intéresse aussi même s’il semble pas très qualitatif sur ce Tamron en plus d’être peu lumineux. le 25 à 2.8 et 35 à 3.2 me motive aussi pour du portrait.
    Je cherche le meilleur piqué.

    Hi Marc,

    Thank you so much for reviewing these lenses. I’m struggling to choose my first zoom lens (Sigma 20-200, Tamron 25-200, or Sony 20-70) for my a7CR. I prioritize a sharp and compact lens, and I know the Sony 20-70 is great, but I keep asking myself: do I really need the 200mm end? I mainly use my camera for city travel and hiking. If I need an all-in-one travel lens, which one should I pick?

    Thanks in advance for your advice!
