  • Hi guys,

    Can you please check this one? I'm mostly concerned about exposure and contrast.

    Thanks!...

  • No, I don't own it. Actually I didn't even realise that Sigma also makes 100-400mm lens, so I really don't know everything about it.
    And re your earlier question, Tamron makes 1,4x and 2x teleconverters, unfortunatley I don't own any of those. But from what I've read they affecting the quality and AF speed. I've tried Canon's 1,4x TC on my 100-400mk1 lens, and they AF didn't work at all on my old Canon 7D body. It's beacuse TC affects the aperture making it f/8, and in older Canon crop bodies AF simply doesn't work with lenses of aperture greater than 5,6. I don't know if it's an issue with Tamron's gear....

  • I own both, the Canon 100-400 mk I and the Tamron 150-600g2. Both are great for spotting, both are sharp and they focus really quickly.

    Canon is smaller and much lighter, so it's easier to handle. You need to think about it, when you plan to go for a spotting trip for the whole day. It starts from 100mm, which is usefull when your spots are "close to action". It's a "pump action" lens, so you can change focal lenght in no time. I use my Canon for over 6 years now and I'm really happy about it, tho last year I had to send it to Canon's service, because that lovely pump mechanism got stuck at 100mm (unfortunatley it's a common thing). Repair cost was the equivalent of 300USD, and after that the lens works smooth.
    Photo examples: all of my AMS shots were taken with this lens: https://www.jetphotos.com/showphotos...d&sort-order=0

    Tamron has 600mm on the long end, so you can use it even for overflight shots. It has much better image stabilisation....
