Tamron SP 150-600mm mk I vs mk II - Klaus - 09-01-2016 <div>So to analyse this new release a bit (MTFs): </div> <div> </div> <div>mk I @ 150mm: </div> <div>http://www.tamron.jp/en/assets/img/product/lens/a011/a011_mtf-chart_150mm_en.svg </div> <div> </div> <div>mk II @ 150mm: </div> <div>http://www.tamron.jp/en/assets/img/product/lens/a022/a022_mtf-chart_en_150mm.svg </div> <div> </div> <div>Not much a difference here ... but at 600mm ... </div> <div> </div> <div>mk I @ 600mm: </div> <div>http://www.tamron.jp/en/assets/img/product/lens/a011/a011_mtf-chart_600mm_en.svg </div> <div> </div> <div>mk II @ 600mm: </div> <div>http://www.tamron.jp/en/assets/img/product/lens/a022/a022_mtf-chart_en_600mm.svg </div> <div> </div> <div>Much higher resolution. </div> <div> </div> <div>10 lp/mm = contrast </div> <div>30 lp/mm = resolution (30 lp/mm is a bit lowish by today's standards) </div> Tamron SP 150-600mm mk I vs mk II - chrismiller - 09-01-2016 so, this on a 5d/d750 or the fuji 100-400 on X-t2? Pretty similar in terms of focal length and aperture. 1Kg (54%) heavier for the 5d combo. Tamron SP 150-600mm mk I vs mk II - JJ_SO - 09-01-2016 Incomparable, I think. The Fuji has on APS-C much less reach, not much better speed and at the end of Fuji's FL range, which is a bit weaker, the Tamron is just sort of "in the middle". Tamron made Sony a big gift.

Message from the marketeers: https://www.youtube.com/watch?v=dv7MmS4iDDY&feature=youtu.be Tamron SP 150-600mm mk I vs mk II - JJ_SO - 09-01-2016 I think, that's alright, Sony already has inbody stablisation and unlike Olympus, which can do both and add the benefits (but probably ad the disadvantage of loosing a bit of speed), neither Sony nor Tamron have a central processing unit especially for the highly dynamic VC. Just realized: "Designed in Japan" can mean the same as "Apple designed in California" (and built somewhere cheaper). One point more for Sigma Tamron SP 150-600mm mk I vs mk II - chrismiller - 09-01-2016 Quote:The Fuji has on APS-C much less reachSurely 400mm on apc = 600mm on ff? The fuji is a 1/3 stop faster at the long end, but FF has roughly a stop advantage so 2/3 stop advantage to the tamron/5d setup?

Tamron SP 150-600mm mk I vs mk II - JJ_SO - 09-01-2016 Don't compare these lenses only on their target camera factor: The Tamron you can put in front of a lot of APS-C bodies, then it's equiv. 225-900 and still speedy enough, plus crops the sweet spot out of the picture. The Fujinon is only for Fuji cameras. But I agree with Klaus, it will be much easier to handhold. Tamron SP 150-600mm mk I vs mk II - Brightcolours - 09-01-2016 Quote: Surely 400mm on apc = 600mm on ff?FF has a 1 1/4 stop (for 1.5x crop, 1.6x crop is 1 1/3rd stop) advantage over APS-C (if the sensor tech is comparable). So a 1 stop advantage of the Tamron. DOF wise same: f2 on APS-C is equivalent to 2 x 1.5 = f3 on FF. 1.4x is one stop (see 1.4x TC's). So, the choice is 1 stop advantage or less size/weight. On reach: if you look at it from a maximum magnification perspective, FF sensors are available with higher resolutions than the Fuji sensors. JoJu makes a good point about the Tamron also mounting just fine on APS-C bodies from for instance Canon and Nikon. Tamron SP 150-600mm mk I vs mk II - chrismiller - 09-01-2016 so my original question was which would you choose? It would seem like the tamron/5d combo is good value gathering twice as much light for only 50% increase in weight. Personally i'm not so sure I want to carry 2.8Kg around. |
