    5.0 out of 5 stars Little to no degradation in quality

    Verified Purchase
    I use this on the Canon 100-300mm f/2.8L. The extra reach is handy and I’ve noticed no degradation in photo quality. It’s much less of a hit than the 2x.

    5.0 out of 5 stars Funktioniert
    Reviewed in Germany on March 19, 2024
    Verified Purchase
    Das ist ein ziemlich binäres Produkt. Entweder es funktioniert oder es ist kaputt. Meines funktioniert.

    Die optische Qualität ist sehr solide. Ja, es kostet Licht (wer das nicht vorher wusste sollte von TKs die Finger lassen). Aber der Autofokus arbeitet sauber da die R-Serie bis Offenblende von f/22 scharf stellen kann.

    Prima dell acquisto bisosa sapere che si può montare sul 100/500 rf ; ma lasciandolo aperto dalla focale 300mm. In su ! Era meglio se si poteva chiuderlo fino a 100 mm.

    Reviewed in Spain on January 26, 2024

    Perfecto para darle un empujón a tu teleobjetivo.
    Lo uso en el RF150-500 y va de lujo. No se pierde en absoluto calidad (comparado con el 2x que también tengo, que si se nota).

    Al igual que con el 2x, la focal mínima pasa a ser 300mm, por la longitud de la caña de la lente interna.

    Por precio y calidad, lo recomiendo al 100%.

    5.0 out of 5 stars Great but overpriced
    Reviewed in the United Kingdom on January 24, 2024
    Verified Purchase
    The extender is great, but considering what you get for your money, a small bit of optical glass stuck between a ring of metal, it is grossly overpriced. The only advantage it has is that it saves you having to carry an extra lens in your bag when outside, and that was the reason I bought it, and for that reason it is a good addition to your kit.
