teleconverter for 600mm 5.6

<p>I am looking for 1.4 teleconverter for my 600mm 5.6 AIS. From the research I've done, it seems my choices come down to the TC-14B or TC-14E, and the 14E would need to be modified in order to work with this lens. Another option is the TC-14C, but I read that this is rather difficult to find. Other than these 3 choices, I know of no other Nikon converters to consider. My question is, between the 14B and the 14E, which would provide better image quality when paired with the 600mm? I'd gladly pay extra for the 14E if it's really worth it. Thanks for your responses.</p>

<p>Once upon a time, I had both the TC-14B and TC-14E (first version), but I sold the TC-14B a long time ago. I don't think you'll see a whole lot of optical quality differences.</p>

<p>As you know already, if you would like to use the TC-14E (first version) or TC-14E II with an AI-S lens, you need to file off the extra tab for the lens to mount. However, the advantage is that the first two versions of the TC-14E can work with modern AF-S (and the earlier AF-I) long lenses. Therefore, if you also have some new AF-S teles, that maybe the way to go. If you only need a teleconverter for the 600mm/f5.6 AI-S, maybe it is simpler to get the TC-14B.</p>

<p>Please keep in mind that the latest TC-14E III (version 3) will not work with your AI-S lens even though you file off the extra tab. The TC-14E III is for G lenses (including E long teles) only.</p>

<p>Alternative could be the <a href="http://www.kenkoglobal.com/photo/lens_accessories/general_lens_accessories/teleplus_pro_300_af_14x_dgx.html">Kenko </a>- I have no experience with it, but it shouldn't need modification and the "pro" version seems quite well regarded.</p>

<p>Thanks gentlemen. Shun, with your explanation, the 14E might be preferable as it gives me options for other lenses. Wouter, I didn't think of the Kenko, but I'll consider it. Has anyone compared the 14E with the Kenko on the 600mm (or any of the Nikon supertelephotos)?</p>

<p>Both the Kenko and the TC-14e would be good solution with a preference for the latest.<br>

Filing the tab on the Nikon converter is super easy with a small Dremel. Just protect the lens with a piece of soft cloth to prevent metal dust to stick on it and be a potential source of scratch. The filing part will take you a couple minutes at most.</p>

<p>Thanks for all the answers. I just picked up a TC-14E with the tab already removed for $175.00. Looking forward to mating it with the 600mm.</p>
