Sigma 1.4x DG EX APO Teleconverter USA

Comments about Sigma 1.4x DG EX APO Teleconverter:

Used the Teleconverter to give a bit extra magnification with my Nikon 70-300 ED

Does what it says on the tin.
Exposure works ok in auto, but autofocus struggles. I just use manual focus.

Comments about Sigma 1.4x DG EX APO Teleconverter:

...the first generation APO HSM lens. I attached the extender with it and the chromatic aberration is obvious, esp between light highly contrast areas. I think it's my lens because the quality of image is much better after I removed the extender.

This is not a knock on the extender. Time to upgrade my Sigma lens I suppose.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I purchased this to expand the utility of my Sigma 70-200mm f/2.8 lens. While the sharpness does go a bit soft, the overall effect of increasing my lens to 100-280mm while decreasing the speed to only f/4.0 seems really useful.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I have been using this Teleconverter on a Sigma 150 macro and a Sigma 70-200 macro and it does a great job.

I shoot a lot of macro shoots and it works well on both lens. I also shoot a lot of wildlife and this Teleconverter does a nice job of helping me getting closer to the birds and animals.

I have nothing to say negative about this Teleconverter. I does what it was built to do, get you a little closer to your subjects.

Comments about Sigma 1.4x DG EX APO Teleconverter:

Build quality and sharpness (when focused manually) are good. However, I bought this for AUTOFOCUS on my Sigma 300mm APO EX HSM and it does NOT recognize the lens and does not autofocus nor set the Aperature. I've tried this on my D200 and D300s. It behaves differently but does NOT work on either body with that lens. My lens IS ON the compatibility list. It is SUPPOSED to work but it doesn't and without it the lens works excellent on both camera bodies.. Assuming that I had a bad copy I exchanged it for a new copy, the new one came today and super disappointed to say that this one does the same thing. It will NOT work correctly. On the first copy if I wiggled the lens/tc/camera I could occasionally get it to AF, but it was like 2% of the time. So far this copy is 0%.

I would have to say that this is why I like to buy new from B&H so I don't get stuck with a lemon. I Love B&H and how they stand behind what they sell. Sure wish I could get this to work, but nothing I've tried has worked. Prior to returning this copy I'm contacting Sigma for recommendations.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I bought this converter to go with my Sigma 70 - 200 f/2.8. I wanted a longer focal length while still being hand-held. The results are excellent. The autofocus works well and the images are sharp. I then added it to my Sigma 150 - 500 lens. The autofocus was lost, but I expected that. With manual focus, I shot multiple images to try to "tune in" to the subject. At 700mm, results are, dare I say, "fuzzy'. But, with less than maximum focal length, some images were good (will still need some post-processing sharpening, but may make an acceptable 11 x 14). Bottom line...buy it for the 200 mm zoom.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I had the 1.4 non DG model and contacted Sigma and they told me I needed the DG model. I was having focusing issues but after "cocking" the camera a bit it took right back off. Not sure if it's the Nikon d90 contacts or the 1.4 converter. I'm using it with the Sigma 120-300 2.8 OS lens. I just couldn't believe the difference the DG model made!! It was like "day and night", literly. I couldnt believe the amount of light the new DG model let in, I don't believe there was any drop off at all!!! The non-DG model was so dark it was terrible. Make sure you get the DG model, it is so so sweet.

I have not taken it off the Sigma lens since putting it on. The build like the previous one seems very good, strong and substantile.

I love the extra reach this thing gives me and at f4, it is so so sweet! Have been thinking about getting the 2x but the price right now after getting all this new equipment is making me wait for now.

The image quality is excellent, I'd rate it probably 9+ out of 10. It is really money well spent especially with a 2.8 lens. Just can't go wrong. I chose B&H due to their amazing return policy that allows you to buy with total confidence. Thank you B&H for your amazing shipping and service. I had it at my door in just two days. Don't wait, get it!!!

Comments about Sigma 1.4x DG EX APO Teleconverter:

Puchased for lenses...Sigma 150 F2.8 OS and Sigma 50-500 OS/
Very pleased with the results on the Macro 150. Very sharp and AF works well, beautiful images of hummers in flight and feather detail is great. Macro is great, but I use manual focus. Will AF but DOF is juat too thin.
Results as expected with the BIGMOS....certainly very usuable and results are ok. Soft at 700mm and it should be, however I will use it for shots where the 500 isn't long enough.

Comments about Sigma 1.4x DG EX APO Teleconverter:

The Teleconverter is small light weight and doubles the usefulness of your lens. I am using this in conjunction with a Sigma 120-300 f2.8 and Nikon D7000. Results are very good, nice sharp images at F5.6 and still very good at F4. Have tried with my Nikkor 70-300 VR but results a bit soft, all functionality of the lens in maintained with both lenses. When using a heavy lens I would not recommend picking up by camera body as this will put a lot of strain on the converter, the 120-300 Sigma weighs(3kg) and would destroy this and your camera mount anyway, Holding by lens and body will see a longer life. All in all very happy with [...] purchase, be sure to check compatibility chart before purchasing .

Comments about Sigma 1.4x DG EX APO Teleconverter:

I have a NIKON D90.
I purchased the 1.4 X DG APO Sigma Teleconverter together with the Sigma 120-400mm f/4.5-5.6 APO OS LENS f/NIKN.
The problem is, that as soon as I add the teleconverter to the lens, the autofocus stops working.
is this normal?

Comments about Sigma 1.4x DG EX APO Teleconverter:

Always wanted to buy this tele-converter and as soon that I acquired the
Sigma 70-200 f2.8 II, I bough it. Works great with My Nikon D300 for birds on a fly and landscapes.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I use this for birding and sports with my 120-300 2.8 Sigma lens good photo quality unfortunately the do not hold up to use they fall apart this is my 3rd and last one if it breaks

Comments about Sigma 1.4x DG EX APO Teleconverter:

Easy to use, just sits between camera body and the lens. Remove lens, attach teleconverter, re-attach lens to teleconverter, removal is the reverse.

Very easy to use, small size so easy to accommodate in a crowded photo bag, relatively inexpensive for the effect it has. Takes my 500mm lens to 800mm do so with a new lens would be much more expensive.

No appreciable change in the quality of images, maybe a bit softer at smaller apertures but not a problem for me.

Nothing really negative to report so far, it does exactly as claimed.

This device has delivered wonderful shots as promised be the manufacturer. I am using it in nature photography and it has worked flawlessly.

I am using the 1.4 teleconverter with a Sigma 150-500mm lens. Very sharp images.Great buy.

Comments about Sigma 1.4x DG EX APO Teleconverter:

Love the new range, when using the TC my d90 Overexposes Up to 1 stop on Aperture mode, I usually do -EV, manual mode is ok though. I just used it recently at an airshow and love the results.I gave 4 starts just because the -EV issue, other than that I'm very happy with this TC.Autofocus works fine.

Comments about Sigma 1.4x DG EX APO Teleconverter:

the SIGMA 1.4 teleconverter is used on the SIGMA 120-400mm telefoto lens mounted on a Nikon D200 using a Manfroto tripod and Really Righ Stuff Ballhead.

This combimation of equipment is used when photographing wildlife, primarily wetland birds.

The teleconverter has worked flawlessly. A potential user must keep in mind that a lens with less than a f/4 maximum opening will have to be manually focused. Not a good choice if you plan on handholdimg a lens this large and manually focusing.

This lens/teleconverter is a good combination for photographers on a modest budget

Comments about Sigma 1.4x DG EX APO Teleconverter:

At first, I was in heaven with this converter. I used it with teh Sigma 100-300, F4 lens and boy, did it work great! But then, after 3 months, the converter started to come apart. And now, it is unuseable.

Comments about Sigma 1.4x DG EX APO Teleconverter:

I have used the 1.4x teleconverter with my Sigma 70-200 mm lens, and I have no complaints. I have used it at a baseball game and a splash dog competition. I have not noticed any difference in the autofocus speed or F stop adjustment. The light is still good with the F2.8 lens. In fact, my friend tried it out; and now he is ordering one this week!
