Tamron 400mm f/6.9 T mount model FO-69

Tamron 18-400 Had to try out this lens, after all, I have every other lens made by just about any other manufacturer, including Tamron but I will not buy a Sigma lens any more. I'm very careful with my equipment and I've had 2 Sigma lenses brand new that just simply broke while under normal use. Of course they were out of warrantee but then that's why it seems planned by Sigma...ya know? Planned obsolescence? But I digress... Back to the Tamron 18-400. I waited a little while to give you a review to get a little usage under my belt. I've had for about 2-3 months now and haven't used it excessively but enough to pas judgement on it, to a point. The first thing I look for is sharpness. I'll try to post full images with this review if they'll let me, if not, I will tell you. I went shooting with my friend and plopped this lens on a Nikon D500. That's the first nice thing about it...the D500 automatically adds 200 mm to the focal length because of the crop factor of 1.5. Now it's a 600mm lens that's nothing to sneeze about. Clear, clear, clear. Sharp, maybe even tack. We don't have any standard that I know about in the industry so in this case it's a 'by the pants' judgement of its sharpness. I would say the final subject would easily be accepted as a professional lens the closer you are to your subject. The further away you get, you start losing the edges. But in any case a 100% crop should always come out acceptable! Next is Vibration Compensation. That's Tamron's expression for camera shake control. I have always been happy with Tamron's VC. It might even be better than some of the lenses Nikon puts out with their VR. The best VC's I've seen seem to be the ones where you might have to pause momentarily to see everything fall into a frozen sate...then you snap the picture...although it's still supposed to work w/o waiting. Whatever, Tamron's VC is great on this lens. The rest is up to the pixel peepers. I didn't look at the edges of these shots to see if there is any focus falloff. You can do that. Anything else? I don't know, it has that good Tamron well-built feel to it and if you buy one, it should be around for a while. I'm one who is in favor of Tamron's lenses and feel safe using them as replacements for many Nikon lenses. Not all but a lot. I definitely recommend this piece. I'm pretty sure you'll love it....and you know the best thing about it? You won't need to carry any other lens with you...no matter where you go. Now that's a statement.Read full review

Not what it's supposed to be ... Compared the maximum zoom (supposedly 400mm focal length) to other lenses, including a 200-400mm zoom from the same manufacturer. The Tamron 18-400mm has an APPARENT maximum zoom of around 250mm focal length ....it definitely does NOT go to 400mm ....

Good Travel Lens As for the 3 question they have asked a simple Yes or No does not suffice. 1. Is it durable, need more time, but it feels solid. 2. Is Image Sharp? I shot with a D5100 and mostly D500. It is great up to about 350 for Wildlife, Landscape is good up to the 400. If you need a single lens to take on a trip, this is the one. 3. Is it a good value? Eh it was what a lens of this type should cost. I like the lens and would recommend it to anyone.
