Summary:
Nice optical quality but incorrect exposure info.

Strengths:
Optical quality good. Purchased to go with Nikkor AF 180mm f/2.8 D IF-ED. No vignetting.

Weaknesses:
When used with Nikon F80, exposure is over by 1 full stop. TC is not sending the correct aperture info. Tamron acknowledges this limitation in the guide with the product.

Summary:
i got my as a gift from my girlfriend who prefers that i am busy with photography than other women. i actually wanted the kenko pro300 1.4x as i am using it with tokina 100-300/f4 but many website claims that the tamron is from the same OEM. however, if you visit the individual web of tamron and kenko you will realise that the technical specs. i.e. the number of elemnets are different. Optically it has been great. if AF very well( even with tamron 24-135 at 5.6 on a bright day)and quick. i have shot some slides setting the tokina at 200mm w/o convertor and then with convertor while maintaining image size. w 10x peak loupe, i started picking fault with the convertor but seriously cant tell them apart. good news. i also took clear sky shots to chek for vignetting and found no dark corners.great lens considering it gives me 420/5.6 with a little more wt only. also done macro at 100 setting with 50 mm extension and the convertor( yea call me crazy but it works!) you get a super macro lens that goes down to 1:1 and a420/5.6 lens what else you want?

Strengths:
optically very good

Weaknesses:
bit pricy considering what it is

Price Paid:  $120.00 from eBay auction item

Summary:
I use this on the Nikon D1 digital and the F5 film cameras. It works well with my 300-2.8. EDIF-AF lens. However it will not work on my 80/200-2.8 or 300-2.8 ''S'' lenses. The ''S'' lenses try to focus using the Tamron SP, but they cant find focus. If you use the Nikon Silent Motor lenses, buy a Nikon e series, it works!

Strengths:
Small and well made.

Weaknesses:
See comments above about regarding use with Nikon silent motor lenses.

Price Paid:  $173.00 from Adorama

Summary:
I use this teleconverter with a EOS 3 and a Canon 100-400 IS, 4.5-5.6 lens, it has worked very well. It limits the autofocus to just one center element, but that is not a disadvantage with the type on photos I am taking. I would recommend this teleconverter!

Strengths:
Retains auto focus functions, Tack sharp and well made. Quick and easy to put on and take off.

Weaknesses:
None
