Hey Hoggers looking for a good 1.4 tele for a Nikon 300mm Als manual focus lens. Any suggestions? Thanks

Nikon made at least 6 AIS versions of that lens, and recommended the TC-14B for each one.

There is not a big difference for IQ between 1.4's . Since you are talking about a prime lens, if you can pick up a Nikon TC reasonably I would. Otherwise, a Tamron SP or Kenko Pro will do you well.

According to the chart: "NIKKOR lenses not listed cannot be used with the AF-S Teleconverters." The OP's lens is not listed.

I like my Kenko 1.4TC on my Nikon lenses.

I own a Kenko 1.4 TC. Less than $150 and can be purchased at B&H. Three recommendations thus far.

Interesting - and - I have seen it before. - but my statement still is - There is relatively little differences between 1.4X's - ON THE SAME LENS - in the 200-400mm range. (IMO) Nikon (and Canon) TC's are optimized for 300+mm PRIME lenses, so they would be my first choice for prime lenses.

For shorter zooms, the Nikon and Canon TC's are NOT optimised for. IMO, third party TC's MAY be better optimized for these zooms because the third party's are optimized for 300mm and shorter lenses.

And, as I have said before, IMO, using a really good lens on a really good sensor - and cropping with well applied pixel enlargement ( if necessary) is better than any 1.4 TC.

Several have mentioned and recommended Kenko 1.4X teleconverters... but unfortunately they haven't specificed which one. Kenko has made about a half dozen different 1.4X in recent years.

You'll have to check their compatibility with your particular lens and camera, but here's a brief overview of the recent and current Kenko:

Teleplus "Pro 300" 1.4X DGX is their more advanced and has been their more expensive model (5 elements in 1.4X) and a good choice for a full frame camera, with good sharpness across the entire image area.

Teleplus "MC-4" 1.4X DGX has been a less expensive model with fewer elements (4 in 1.4X) that's quite sharp in the center, but not so much in the corners... so it might be great on a crop camera, but not on full frame. I think this is still in production, although I thought the "HD" (below) might be superseding it.

Teleplus HD 1.4X DGX is their newest model. I don't know how it compares for image quality. This appears to be a simpler TC with fewer elements (3 in 1.4X) than the MC-4, but it is currently the most expensive. While it's listed as "for Canon" many places (and is the only TC that can accommodate Canon EF-S lenses), according to the Kenko website there also is a Nikon AF version.

All the "DGX" TCs have integrated circuitry that supports full communication between the camera and lenses. The MC-4 and Pro 300 models were earlier offered in "DG" versions that lacked this circuitry. Of course, with an older AIS, manual focus lens this isn't important. But it may be if you ever want to use the TC with any other lenses in your kit.

Which is exactly what I do.
