Sigma teleconverter 1.4x: Any feedback on Sigma teleconverter 1.4x on a Nikon D80 using 18-200 Nikon Lens ?

I read somewhere it does NOT work. I would not recommend this combination anyway fr quality reasons. It is a bad idea to use a converter for a wide-to.tele-zoom. Teleconverters are best for fast lenses (2.0...4.0) and longer focal lenghts (fixed or fast pro telezooms).

This adapter has a removeable '1.4X teleconverter (infinity adapting) supplemental lens' insert. When I use the adapter WITHOUT it's supplemental lens on my D5100, I need to calculate the camera's compressed sensor value for a full frame lens! IE.: 50mm fullframe lens to my camera's compressed sensor, with the adapter's supplemental lens NOT IN place, is (50mm x 1.5 = 75mm) ~~~infinity focus is weak When I use the adapter WITH it's supplemental lens on my D5100, I need to calculate the camera's compressed sensor value for the full frame lens! IE.: 50mm fullframe lens to my camera's compressed sensor, with the adapter's supplemental lens IN place, is (50mm x 1.4 = 70mm) ~~~infinity focus is strong

I am a Nikon Shooter so I have used the Sigma 10-20 f3.5 with a D3200 crop 1.5 sensor and a D800e full frame sensor. This lens will work on both. But on the D3200 I get a 24 MP image and on the D800e at switches to DX mode and I get a cropped 19.2 MP Image down from the 36 MP full frame image. I hope this helps.

I don't think so, because sigma have their own teleconverter for this lens.Even Nikon. Nikon have their own teleconverter for their own 70-200 and that's not fit on any other Nikon lens.I guess you gotta ask sigma. They have contact info in their website. Good luck!

Teleconverters usually work better with faster glass but if you have lots of light should be no problem. Use a tripod as you take a 300 on a Cmos now your at 450 and add a 1.4 at 675

The link for the comparison at cameralabs.com is not applicable because it tested the Sigma 18-200 DC prior to the release of the OS version. The OS version is much better optically than its predecessor and also includes HSM (High Speed Motor). I have read test reviews and comparisons at other sites such as popphoto that indicate the Sigma is sharper and has less distortion than the Nikon 18-200 VR, but they also state it is slightly louder. I just received my Sigma 18-200 OS today and have done limited testing, but I can tell you the AF and OS noise are not bad (the OS chirps when it turns on and off). The Sigma AF is louder than my Nikon 18-135 (w/SWM), but quieter than the AF on my Nikon 50mm 1.8 prime (wo/SWM). The HSM AF seems just as fast as my Nikon lenses. The build quality feels better than the Nikon 18-135; the zoom is smooth and solid. The first things I tested today were barrel distortion and OS functionality. Barrel distortion is present at the wide end on ALL wide-range zooms, but the Sigma controls it better. The Sigma has noticeably less barrel distortion at 18mm than my Nikon. This benefit of the Sigma is moot really, because barrel distortion of both lenses can easily be corrected with software. The OS functions very well, I can shoot hand-held down to 1/10th of a second with no blur. I will post again after I have time to do more testing.

The teleconverter I purchased was for Canon product and would only work on certain lens types. You'll need to review the Nikon compatible teleconverter specifications and check with Nikon to determine what lenses it will work with.

Big issue on using teleconverters is lighting. if you don't have good lighting then no. also the speed of your focus has an impact in performance. slow autofocus and you camera will hunt. I ha d a sigma 70 - 300mm lens and it did ok. but my tamron is so much better. especially with teleconverters. one thing the keep in mind. your f factor with change with these.so an f4 be much higher. hence lighting issues.I have even stacked them with mixed results.I have a nikon D3100 with 2 nikon lens, 18-50mm and 50-200mm, and a tamron 70-300mmand 2 of these teleconverters.

I am reasonably sure that the 1.7 teleconverter will work with your 300mm f2.8 on your D800. I use mine on all of my Nikon cameras (D750, D7000 and D300) with my fast lenses (70-200 f2.8 and 200-400 f4.0) and autofocus works just fine.

Mike: We use this lens on a Nikon D800 and it is an excellent lens. We had used Sigma lenses for years with various earlier Nikon cameras and the Nikon 18-300 is sturdier and gets much better resolution. Ours is the stabilized lens which also adds to the quality of photos. No experience with a D-80 however.

I would think yes, I use it on my d700 with a Nikon 70-200 VR11 lens with excellent results. I don't think Nikon changed anything about the mount on the d800. If they had there would be a new Teleconvertor for the d800.

The teleconverter works best with F2.8 lenses. AF may not work well at higher F stops and you may need to go to Manual focus

That would be a question that should be answered by a rep from Sigma. It works great with newer cameras, but I'm not sure about D80.

I am very happy with this lens. I have not tried the Sigma. I have the tamron 28-75 and the 70-200 VC both outstanding lenses - fast and sharp. Tamron is slightly more expensive and reviews always slightly higher. Sorry I could not give you more info about the Sigma

Sorry, but it is not compatible with the lens. You generally need a 2.8 or larger (smaller number) aperature lens. You should go on the Nikon websiteand check the teleconverter compatibility chart before buying a teleconverter or lens to use with a teleconverter.

Hi, Jason. You tend to see some degradation in image quality as well as some vignetting with the 2X teleconverters. While the canon is better than say a Sigma or a Tamron it will still affect image quality some. Using the 1.4X, at 200mm with the 70-200L, I have seen some very minor loss in sharpness in the corners, however I have to pixel peep to see that.

I am not really sure that the converter will work in auto mode. Usually, teleconverters are not too successful with slower lenses. I use mine with lenses that can deliver an f4.0 or larger aperture.
