Lens Doublers
Jul 2, 2014 11:34:21 #
The lens I'd love to have it way outside my budget, so I am considering a lens doubler for my Nikon 70/300 zoom. Any thoughts as to how well these thing work before I lay down my $$$$. Thanks.

A Nikon 2X TC will not mount on that lens. An aftermarket 2X TC will mount, and function. But you will have no autofocus, the image quality will be seriously compromised, and due to the focus screens in todays DSLR cameras manual focusing will be difficult if not impossible to accurately set.
Save your money for a good longer lens and forget the doublers.

Kinda what I thought, too. I was just curious, as I didn't know anything about doublers. Thanks.

I shoot Canon not Nikon so can not help you with that particular lens. I can tell you though that I own a couple of 2X TC's and no matter what lens I try to use them with there is a reduction in the quality of the photo.
If you can not afford a better quality lens give a 1.4X TC try. As a general rule you can get good quality photos using them. MT may be able to help you on this. My "go to" third party 1.4X is normally the Tamron TC.

A 1.4 TC will work on this lens. A little slow on the auto focus in low light and a little softness in the photos. Lens envy is a bitch.

It can get you into a lot of trouble, especially if you are married!
As always I suggest you get the best lenses you can afford, with "AFFORD" being the key word!

TC's might have some value if the lens resolution is better than the pixel resolution of the camera (I know that this is subjective) This applies usually to very expensive large prime lenses or low resolution cameras
Otherwise PP clipping gives the same or better results (PP clipping involves no additional optical elements and does does not reduce the amount of light arriving at the sensor, Yes darker affects IQ only indirectly but affect it it does in most real life situations, if you use a tripod for landscape pics in bright sunlight go for it)
The advantages of a TC mentioned by previous posters in other related threads ,include not having to PP your pics before bring to walmart for prints, the ability to brag about "tack sharp" pictures , larger /darker view of subject in the viewfinder which might be useful for the visually impaired in bright sunlight
The question posed by the OP was not "can I be happy with a pic I took with a TC" but rather he inquires or should have, "will the use of a TC give me a better pic, than I would get without a TC after a bit of PP"

Who knows, that may be his next question. As for now it is not what he asked. He did ask " Any thoughts as to how well these thing work (2X TC's) before I lay down my $$$$." So far the answers seem to be leading him away from getting a 2X.
He made no mention of PP so we have no way of knowing if he has the capability of doing any, or does any, PP. We ned to remember many new members don't do any PP.

I am sure that you mean a lens extender. A lens doubler would be a gizmo the somehow makes 2 lenses out of 1 LOL

On the other hand 1.4 TC's like vivitar are cheap, so even if they are not perfect, if there is a chance they are useful, they are worth trying. A long lens is a big investment!

I went to Alaska in June. Used my Canon 70D with a Canon Zoom Lens EF 70-200 1:2.8 IS II USM and the Canon EF 2x III. I got some good pictures and some not- so-good pictures. I will try to get some photos posted on the 4th or 5th of July so you can get an idea. My conclusion is that the 2X III is very good if used correctly.
I have a 400 mm prime lens, but didn't want to add it to my camera back pack when traveling.

Actually the Tamron will work. Not as well as a real long lens and you lose two f-stops. The focus is no problem. You have to manual focus, but most of the newer Nikons use phase-shift focusing and have a little green dot when in focus--even in manual focus. I've had no trouble focusing with my teleconverter. Of course the image with my Sigma 400mm and a Tamron doubler is not as good as a true 800 might be. But it is pretty decent and a lot better than not getting the shot.

I do get some decent shot on occasion but the percentage of keepers is no where near what I can get using a 1.4X. The only time I bother to mount the 2X is if I know I am going to be shooting stationary subjects.
I do keep my Tamron 1.4X on my 500mm lens quite often. Tracking a BIF can be a challenge at times, it makes the lens a 700mm prime, but the results can be worth it.
