Well... really impressing performance of the Tamron 150-600 VC.Canon Rumors said:Roger and Aaron ... have completed their resolution testing of a host of supertelephoto zoom lenses.
The Sigma 50-500 OS and Canon 100-400 were the two big competitors to the new Tamron 150-600 VC

Whatever that is, it triggered AVG for a web-based exploit.

If I understand it correctly, it's your typical Imatest result like on Photozone. The ordinate is LW/PH.
I can't tell if it's center and edges, or center and corners, or center and average. But they go on pretty close, so it doesn't really matter. It's just good
I think they used a 5D MK III. As an approximation based on other available imatest data, 600mm f/8 is very, very close to the 100-400 L at 400mm f/5.6. Only very slightly worse, if you consider the error margin.

The dark blue is horizontal resolution and the light blue is vertical resolution base on the test chart (red box scale area).
Have a nice day.

Well, you don't have it either, unless your specific copy of the 100-400 L goes up to 600mm![]()
OK, that makes sense ... I hope Canon/Nikon lower their lens prices, but I doubt that very much. I use (and have used) lenses from the 3 big third party manufactures (Sigma, Tamron & Tokina ... also use a Rokinon/Samyang 24 T/S lens), but I personally feel that their earlier quality control issues and Canon/Nikon tactics of "camera firmware upgrades" (that mysteriously "change" the way the 3rd party lenses AF) may continue to haunt them for some more years to come ... I see its changing, albeit slowly, but meanwhile Canon/Nikon will continue to charge higher prices as long as possible.[email protected] said:Thanks, & sorry for the ramble. The gist:Rienzphotoz said:Welcome to CR ... now that is one heck of a loooong first post I've ever read on CR ... now could you please elaborate (oh God, no!), I did not mean elaborate, I meant, could you please summarize, what exactly it is that you want to tell us, coz I kinda lost you after the "crapp!ing ceramics" part ;D
The 150-600 lens appears to be a better lens for most people in the market for a low-end super-telephoto.
AND
This signifies a moment in the camera market where it makes sense for Canon to act strategically differently than it has acted over the past 10 years. Those strategy adaptations will lead to more power in the low end, lower prices and some pain-in-the-rear Canon policies (weird pricing and/or availability issues between countries) that would otherwise seem nonsensical.
One additional thought & reason why I think this 150-600 lens signifies greater change:
Sigma and Tamron have plainly decided that the money is in the upscale market. That decision was probably made 3 years ago to produce the new lenses we're seeing coming out now. That means that there could be enormous additional disruption coming out by lens designers who have been beavering away since the Black Eyed Peas were on the charts.
Great time to start an interest in photography.

If you could consistently get as good or better results that the 100-400L at a lower price with better stabilization and reach, that's a big deal.

So far the 3 samples that Roger has are all centered will very little sample variation according to his report. Looks like a good start for QC.
Lee Jay said:Here's my problem with that chart. Unless I'm doing the math wrong or not understanding what this chart means (certainly possible since it's in Chinese), the f/32 numbers are beating the diffraction limit, calling the entire thing into question.
CarlMillerPhoto said:Ya if you have the 120-300 2.8 that makes things tricky. I think that lens (+ext) vs. this Tamron is the big question for those looking to get into the super-tele range on a budget.

Thanks for solving the mystery! ;D
Could you also clarify if it's center resolution or an average or...?
