I guess the obvious follow up question is do those of you who have used both the Tamron & the Canon 1st gen 100-400 think the Tamron is superior? I have a local guy with a pristine 1st gen Canon asking $650.

Take it. Good lens at good price.

id pass on that 100-400V1. for $150 more you can get the tamron where its IQ is pretty much on par with the canon 100-400II, is weather sealed better IS and is brand new with a warranty.

I made the decision to try the Tamron 100-400. It should be in early next week.

I'm still really torn between the Tamron 100-400 and the Sigma 100-400, and keep going back and forth. I need sharpness on the long end, and the Sigma seems to be a touch better at that (the Tammy being better in the mid range as far as sharpness goes...) But the Tammy is said to have better AF. (the Canon is out of the running for me as it's much heavier, larger, and more expensive than I can afford.)

Right now the Sigma is between $130 and $150 less here in Canada than the Tamron, and my tax return only stretches so far... :) So that becomes a factor. But the Tamron has the optional tripod mount, and is a tiny bit lighter... Decisions, decisions!

And always in the back of my mind is the Canon 70-300 ii - lighter, smaller, super fast and sharp. But I think I'll regret the lack of reach - I want to shoot birds and critters. I know I can crop, but how much becomes too much?... I'm using a 77D. Someone tell me what to do!! :):)

I dont think you will go wrong with either the Sigma or the Tamron. The slight difference between them in IQ is pixel peeping level.

Dustin Abbot's review on YouTube really helped me choose the Tamron, with the biggest factors being AF performance & aperture size over the zoom range. The Tamron starts with a wider aperture than the Sigma and it maintains a wider aperture across the entire range. I've included a screen capture from his final video (there are 3) on the Tamron & provided the link (external link) for the video as well.

I had forgotten about the difference in apeture across the range, though i did see it in Dustin's review. That will make a difference, though I think I'll likely be using f/8 a lot for what I'm shooting.

The other big difference between these 2 lenses is in maximum reproduction ratio - 1.38 for the sigma, vs. .27 for the Tamron. Some are saying you can do "fake macro" closeup work with the Sigma, though with the small aperture I dont' see how you could isolate a subject.

Now I'm leaning toward the Tammy... Man - if every decision in my life were this difficult I'd never get out of bed! Part of the delima is that I can't handle either lens before buying - no camera store on the Sunshine Coast where I live, and even if I got into Vanouver, none of the Vancouver stores are carrying the Tamron. So it's online buying for me...

Which brings up another dilemma for me... the Tamron is available on ebay from Japan, at $300 CA less than I can buy here in Canada. But I'm not sure I want to take the risk. A deal is always great until it isn't, and getting a lens (even from a reputable seller) that has a problem would be a real pain. But is $300 worth taking that risk?

the ebay one is probably a gray market version. Tamron took a new policy with that like Nikon did. if you buy gray market they will not work on repair even if you are paying for the repair

Wow - good to know. Yes, it would be gray market in North America, as it's the Japanese domestic version.

I thought about that as well and I ended up purchasing from an authorized US dealer on ebay. The only reason I went through ebay is because I received a note from ebay telling me if anything I purchased yesterday through today would receive 8% back in ebay bucks. This ($63.92 US) will cover the cost of buying the tap-in console and made it a no-brainer for me. I just didn't want to take the chance on a gray market product.

I saw that - unfortuantly the US sellers on ebay have to charge duty on equipment into Canada, which is adding between $55 and $70 to the price. for that I may as well buy in Canada. (Plus - and this is totally off topic but frustrating - Adorama is experiencing a glitch in their ebay ordering system and cannot ship to Canada! I wrote to them because I was interested in a bag, and the shipping calculator would not work with my postal code, and that's the response I got. I'm really disappointed, because they are the US seller I would most trust on ebay.)

That's firmware, which can be modified without disassembling the lens, vs re-chipping that required the lens be disassembled in order to remove and replace an integrated circuit or board. The later having more risk to the end functionality since there's opportunity to mess up element alignments and such. Sigma's (pre-Art/Sport/Contemporary​) are the only ones I'm aware of having to be re-chipped.

Again, with the way the newer lenses are made, that's all pretty well mitigated by the docks. Aside from the fact that both still have to do their own blackbox engineering to keep up w/ the manufacturers' af systems, I see little reason to be concerned about the modern offerings from Sigma/Tamron specfically, or most other well-known 3rd parties.

I find this odd. Has NAFTA been repealed? I can buy camera gear from Japan and not pay duties on it. Last time I looked, Japan was not in North America. What's up with Canadian duties?

BTW, I've also purchased camera gear FROM Canada and paid no duties.

I’m sorry, but I understand there is a permanent glitch on eBay's calculator with regard to certain Zip Codes in Canada.

Sometimes it works and other times not; and there is no manual override option.

No, NAFTA hasn't been repealed (yet...) but the shipping options that American sellers are using adds a secondary import charge (for instance - the Tammy 100-400 from samyscamera has a priority shipping charge of $27.99 CA to my postal code PLUS Import charges of $57.56 US - around $75 CA - so over $100 CA shipping on top of the lens cost.) Cametaauctions doesn't add the additional import charge, but adds it into their initial shipping charge, which is $85.15 CA. With our lousy conversion rate, and those shipping charges, it makes more sense to pay $1129 here in Canada with free shipping.

So I can save hundreds buying gray market and hope to get a perfect lens, or bite the bullet and buy Canadian...
