Two Teleconverter questions
Apr 27, 2018 07:26:21 #
I have a Nikon D750 and a Tamron 150-600 lens. I'm looking to purchase a teleconverter in order to get closer view of birds.
1. Do I choose a teleconverter based on the lens (Tamron) or camera (nikon), or does it matter?
2. Should I limit it to 1.4x teleconverter in regards to minimizing loss of image quality?
Personal experience/reviews welcome

And getting closer by foot isn’t an option?
It’s already an f6.3 at 600mm, so you’re going to need even more light with an f1.4 attached to it.

The TC is for the camera, if shooting Nikon, get one that fits a Nikon camera.
The 1.4 would give better IQ than a 1.7 or a 2.0

If you're not concerned with the loss of light, do some research at the manufacturers and if you chose to get one, make sure it will work with that lens.

If you have the Tamron G2, there is a special teleconverter made by Tamron. The 1.4x gets good reviews, the 2.0 less so. I have the lens, but not the teleconverter. I have a Kenko 1.4x which I can use with that lens. It works ok--but with some odd autofocus issues at times. I have an old Nikon 2.0 for manual lenses. In a pinch I will use it with manual focus. If I expected to use it a lot, I would get the Tamron 1.4. I find it easier to use the lens on a crop sensor body for a 900mm equivalent.

No, I was trying to capture waterfowl. I had to do an awful lot of cropping in PP.

Your D750 will have difficulty with autofocus for lenses / converters slower than f/5.6, see page 430 of your D750 manual. When considering a TC, consider the resulting effective maximum aperture. Assuming your Tamron is the model that ranges from f/5 to f/6.3, you can use a 1.4 and retain auto-focus for the lower end of the zoom range. At the maximum 600mm, you may have inconsistent autofocus or a manual focus only lens. For question 3 to add to your list, should you purchase more equipment that turns in auto focus lens into a manual focus lens? I'd read very closely all reviews that address specifically your model camera and the specific lens and teleconverters to confirm performance of the combined configuration.

Thanks for the info. It was my impression that the 1.4 was a better choice.

This answer only answers the question of the fit for the teleconverter to the camera body and is correct. Buy one to fit the body. However this doesn't answer the real question of which converter works best with which lens. I believe that is the question being asked.
Generally, it is best to buy a matching converter for the lens that it is to be used with. That is most likely the safest answer. Check with Tamron and go with their suggestion.
And yes! you will not be able to use anything greater than a 1.4X converter. Your lens will not have enough light to work as designed and will not autofocus or at best will hunt for focus too long to be useful.

If your lens is already F/6.3 at 600, where will it be with a 1.4 converter? F/8 or higher? If that is the case, I suspect (if you are trying to get quality images) you are going to need a lot of light unless you push your ISO to compensate (which will reduce image quality). Considering bird photography is best in the early AM or evening (lower light) I'm guessing you will be shooting at ISO's that will frustrate you re IQ. Then there are the focusing issues referenced by others. I think that is why converters are really recommended for prime lenses (f/4) which with a 1.4x will give you f/5.6. I think if you are really serious about bird photography your will eventually be considering prime lenses which get expensive at these focal lengths. Frustrating isn't it? Bird photography can be frustrating for those without patience nor those not willing to make the investment in the proper equipment. Good luck!

You will not be happy with the image quality and the autofocus performance when you use a TC with any lens that has F6.3 for a maximum aperture at full zoom, even with the 1.4X.
The better alternative is to be patient, sit still where the birds are that you want to shoot, and they will eventually ignore you. Getting a longer lens involves a tripod and gimbal, since it is not likely that you'll be able to handhold an 840mm lens.
Supposedly Tamron's 1.4TC has less of an impact on image quality and AF performance.
This is a good video review that offers some insights on using either TC with the 150-600

Fran, actually, that's misleading as far as using a Nikon TC on a Nikon body. The TC is mated to the lens. You use the best TC for your lens that can mount on your camera. If you want a TC for the Tamron, you get the Tamron TC. If you had a Sigma, you'd use a Sigma TC.

... And there we go again 🤣🤣🤣🤣🤣
I have a similar problem, but instead birds is bears, wolves, wolverines, mooses, foxes and reindeers.
I wrote a post here with 100 of comments and 4000 of viewers and guess what, I finished even more confused than before.
Instead people answer your question (actually like I'm doing right now 😂😂) they just want to tell that you/me should get close (good idea, bears are so peaceful), you/me will loose light (OK, good to know) and the autofocus will not work (blaaaa).
Whatever, back to the question: A TC is for the lens, but anyways goes for the camera as well, if the lens is for Nikon, the TC will not work in a Canon, well, I guess.
Cheers

Make sure you check for rear glass clearance. My wife found, with her Tamron 150-600, that only an early series Tamron 1.4 TC would fit. The later series Tamron TC, current model, wouldn't fit and nor would any Nikon. Just beware before ordering online.
