Tamron 150-600mm lens with nikon 1.7 tele convertor
Jan 24, 2016 15:06:23 #
will a Tamron 150-600 be compatible with a Nikon brand 1.7 tele convertor? I know that Nikon does not list it, but they are not too friendly with 3rd party products.

I do not think any of them will work. You would lose at least one F stop and the lens is not fast enough. If you could you would have to manually focus. I would not know why you would want to any way. I use a tele converter and it is F4 lens, but that is about as slow a lens that I would want to use one on.

Those are your choices, along with the 1.4 and 2.0 TC's from Sigma and Kenko. You will lose AF with almost all of them.

Even if it did mechanically connect, you won't be happy at all with the handling. Trying to manually focus through an F9 aperture is hard. Also, what kind of tripod are you using? You can forget about anything but a Gitzo Series 5 or a RRS TVC 43 or 44 if you want stability - a 1000mm lens requires very solid support. If you are using a crop sensor, it will be even more demanding.
TCs are intended for a very specific and narrowly defined use - to take fast and exceptionally sharp telephoto prime lens (with generally two exceptions - the 70-200 and the 200-400) - and magnify the image cast onto the sensor. You will give up about 5% sharpness with a 1.4x TC, about 15% with a 1.7 and as much as 25% with a 2x.
So if the lens you intend to use with a TC is slightly soft at 600mm (like the Tamron), you are only going to degrade the image further.
Save your money.

I have a Nikon D7100 with Nikon 18-105mm and Tamron 16-300mm. I use a Kenko TC 1.4. With booth lenses the AF is working.

OK, even if it did fit. Welcome to photo math 101. Some Nikon camera's need a minimum F8 to auto focus. So, with this in mind, the top end of your lens is, what, F6.3. So, follow closely, F 6.3 times 1.4 equals F 8.82.
And, as we all know, 8.82 is greater that 8, so class, your lens will not auto focus on a nikon body at the top end of the lens reach even if a 1.4 could fit. Now I have to ask this question, and this is assuming you have a full frame camera, what do you need a 840 MM lens for? Anyway.

I used to use the lens on a d7100 and enjoyed the perceived reach it gave me, and was hoping a teleconverter would simulate the 1.5 crop of the dx camera on my d750. i like to photograph birds and presently cannot justify a &10,000 plus investment in a prime lens. I am learning that this is not possible.

Sorry but your math is wrong. You only lose about one stop with a 1.4 TC.
And only a few Nikon cameras will focus at f8. For most it is 5.6. Don't know for the D7200.

True, but one stop below f/6.3 is about f/8.8. It is f/5.6 that is one stop more open than f/8. F/6.3 is about 2/3's of a stop above f/8.

I have that combo, the D750 and the 200-500 mm f5.6 zoom. It is an fantastic combination. I use group auto focus around the central focus spot and it will take almost everything you have to get. Or at least, it does for me.

Sorry, your reply is wrong, you lose exactly 1.4 stops with it, just like you lose 2 stops with a 2X and 3 stops with a 3X.
