I am thinking of buying a tamron 100-600mm lens. I already own a canon 100-400L lens. My question is the 400 lens has a min focus at 1.8 meters while the tamron 100-600 has a 3 meter minfocus. If you take a image of the same object at min focus range with each lens is there much difference. I take a lot of shots of flowers,critters and other objects where i have to back away until i get the object in focus. Just wondering if backing away from the subject one more meter with the tam 600 the images might be the same size.Iam sure if your at 50 ft there would be some difference.

The Tamron is not 100-600 lens, it is 150-600, to correct you in case needed. But I have neither of those lenses so I can not answer your question.

Ron, I wouldn't know, but you need to check the max magnification stat for each lens.
For macro, you can use them with a set of extension tubes. You lose infinity, but gain magnification.
Good luck

Ronjay,
Check out this thread. Considerable discussion about the Tamron 150-600mm lens.

As mentioned, You would have to look at the "magnification factor" for each lens - but I do believe the Canon is slightly better in this regard than the Tamron. The 100-400 is a great lens for closeups and if I were you, I would get the Canon 500D close up lens or the XPro f-500 to go on the front of the lens for even better close up capability - and forget the tube (s) ...

ronjay,

If you're taking "a lot of shots of flowers, critters and other objects where I have to back away until i get the object in focus", why not just get a good 100mm f2.8 Macro lens? This will get you in close & give you better DOF control.

I have the Canon 100-400mm f4.5-f5.6L IS USM but I've never used it for macro work. I had the Tamron 150-600mm on order but canceled it. I don't bring out the Canon all that much & I have the Canon 2X converter that fits the 100-400mm giving me an effective 800mm range (albeit with the loss of two stops). I normally use this lens on a Manfrotto tripod & ball head. That said, I took this handheld at the Pittsburgh Zoo braced against a wall.

Great shot of the Tiger ! ......But you are missing out on the great capability of the 100-400 by NOT using it for macro/close up work ! I regularly use Sigma 100-300 F4 W1.4X and Canon 300 2.8 W/2X for close up macro work ......

I have had the Tamron 150-600 since it was released early this year. I sold the lens yesterday, because I just cannot live with it anymore.

I sold it for 40% less than I paid for it, and I'm so happy to be rid of it that I'm not bothered about losing such a big chunk of money.

Firstly there was an issue with it battling to find autofocus. This was resolved when I discovered that there is a 'secret' firmware upgrade that Tamron didn't feel it important enough to let their customers know about. 3 Weeks after shipping it off for upgrade it came back and was able to focus like a normal lens.

So, that fixed the autofocus issue, but no amount of workaround would solve the fact that it is just a soft lens at all focal points. (At least my copy was). A photo of the sharpest tack would make it look blunt. I joke that even a couple of Viagra wouldn't cure it's softness.

With a Canon lens it would have been easy to get the Canon service guys to sort it out, but with Tamron, every time I need it looked at, I had to ship it cross country and wait 3 weeks for it to get back to me. Eventually the aggravation factor got to me.

I'm sure the lens is repairable but I haven't got the patience and time to force Tamron to do it. Tamron products may be good, but their service is hopeless, and I'm not prepared to live with that..
