Whenever I use the Tiffen 2X tele extender (at full zoom ), I always get vignetting in the corners. Other posters have indicated no vignetting in corners. I'm shooting with a G1, plus lensmate and Tiffen adapter. The effect is very pronounced in sky shots, and sometimes cropping is not a good option for me.
Any suggestions?

Could you post some examples? I have the Tiffen Megaplus 2x and the amount of vignetting that I get, to me, is negligable. But vignetting is subjective, so what you are seeing may be normal. On my shots it is only visible at the top if there is nothing but light blue sky. If there is anything dark at all in the corners, I don't see it.

Here's a couple of examples from my 2X. Neither of these have been cropped, just re-sized. The first photo is the Colorado river at the bottom of the Grand Canyon, taken from the South Rim (it's 1 mile down to the river) - you can see a very slight darker area in the upper-right corner, but to me that is not significant. The 2nd photo is of Delicate Arch in Utah, also about 1 mile away. Here you can see the darker areas in the upper corners, but to me, that's not a problem.

Gus, I can't provide you with an example, because I have cropped the images. I am selling images of boaters passing through an inlet, going out to sea. The vignetting that I'm experiencing is worse than your example, though. I've tried shooting at maximum aperture, but the slower shutter speed gives me a poorly focused picture! I just can't win...BTW, I liked your Grand Canyon pics.

Is it the MegaPlus model? Which adapter are you using? What filters, if any.

Yeah, the smaller the aperture (larger f/number) the less vignetting you'll get. One thing you might want to do is manually dodge the corners in Photoshop or if it's just plain blue sky, use the clone tool to copy some non-vignetted blue into the corners. I use the Tiffen adapter instead of the Lensmate and I believe that's the best option for getting the 2x as close to the G2 lens as possible. If you're using the special thin Tiffen step ring, then it shouldn't be too different though (I'm assuming that you're not using any filters between the G2 and 2x or on the end of the 2x).

I personally haven't had too many instances where vignetting is a real problem, and I find that a tiny bit of work in Photoshop will fix it up just fine in those few cases.

Justme...it is the mega plus, using the tiffen adapter,and no filter.mickey.....I'm processing between 50 to 70 pics at a time, so cleaning up with the clone tool is a little more labor intensive than I care to do.

Bob....vignetting are gray/black shadows in the corners of the image, caused by the addition of a tele extender that blocks some light....so the gray/black effect is actually a shadow. Hope this is a correct explanation.

Can you explain what you mean by "plus lensmate and Tiffen Adapter"?

With the lensmate you only need a step ring for thread matching. The Tiffen "adapter" is normally what you would use instead of the Lensmate adapter.

Just questioning what the definition of "Tiffen adapter" is.
 
I assume he means that normally he shoots with the Lensmate with maybe a U/V filter, then when he wants to use the 2X Tele, he removes the Lensmate and screws on the Tiffen adapter with the Tiffen 2x tele.

But anyway, I did some test shots with the three combinations you can have. The top one is with Lensmate adapter and Bower (standard) 49/43 step-down ring. The next one is with Lensmate adapter and the special Tiffen narrow 49/43 step-down ring. The 3rd photo is with the Tiffen adapter only - no ring is required. The 3rd option sets the 2X the closest to the lens and is the best option to use. But as you look at these photos, you will see there is very little difference, not really enough to worry about. However, when I am out shooting with my G2, I leave the 2X attached to the Tiffen adapter, then when I want to swap, I just switch adapters. Here's the photos, from worst case to best case.

I suspect Earl means the 49-43 step ring and not "tiffin adapter". It seems desirable to get the co-planer step ring which sets the lens closer than a standard 49-43 step ring and reduces vignetting. As already mentioned it is important to always have G2 on max tele.

Earl,

Thank you for the explaination on the Vignetting, now I understand what everyone is taking about. I will be looking to get a 2x for my G2. What do you reccomend??? And what adapted to mount the Lens works best??

The only 2x tele for the G2 is the Tiffen Megaplus (43mm thead version). I have one and I love it. Your other options are the Canon 1.5x, Oly B-300 (1.7 or 1.8x), or Oly A-200 (1.5x). Apparently the Canon and B-300 are of higher quality optics, but I haven't seen anything to prove that. In fact, I've only seen one comparison between these lenses and IMO the Tiffen looked the best, or at least the same as the B-300. Anyway, if you want 2x, then the Tiffen is the way to go.

I think the 43mm Tiffen lens adapter is your best choice for attaching the 2x, although I also own the Lensmate (49mm) for my filters and leave it on all the time, except for when I swap it with the Tiffen adapter/lens combo.

I also have the tiffen megaplus lens, the tiffen 43mm adapter, and a lensmate with a 49-43 step down ring. I have been leeping the lensmate on the camera and the 49-43 ring on the lens. I figure it is less wear on the camera to NOT be screwing things on and off the camera body frequently. The Lensmate is alot cheaper to replace if I strip any threads!

Do people think I'm being too cautious? I can't remember right now, but are the threads on the G2 body plastic or metal. If plastic, they are even more vulnerable to damage--especially from a metal adapter.

--Bob
 
Earl, take a look at the 3 examples I posted above. You can see where the Tiffen adapter (which uses no ring) does the best job. I don't think anyone will disagree with that. So if you want to use the Tiffen 2x, and you want the LEAST amount of vignetting, that is the way to go. I'm sorry, but NO ONE is going to say that you will get NO vignetting. If that's an absolute requirement, then forget the Tiffen 2X. Having said that, I'll be quick to say that I am VERY happy with my Tiffen 2X and I'm sure a lot of others will agree. If you want to spend a lot more money for a 1.5 or 1.7, just to get rid of the last remnant of vignetting, that's fine. People have different opinions of what is important.

Earl:

I have the Tiffen 2x teleconverter and the Tiffen adapter as well, and used them extensively with my G2 on a recent month long shoot in Alaska and Siberia. I also had Canon's 1.5x teleconverter with me but did not use it all. It just did not give me the reach I needed. I did get those little gray shadows in the upper corners, but they were easily either cropped out, or removed with Photoshop's clone stamp. (They were particularly noticeable whenever I used a Polarizing filter on that lens, probably due to the thickness of such filters.)

I posted a full report on the G2's performance on this trip, along with links to my pictures, on this forum a few week ago. Just search for my name (Phil Douglis) in the search box for this forum above, and it will take you to the thread. Although the pictures made with the Tifffen 2x teleconverter on the G2 are not labeled as such, almost all the shots of distant wildlife, birds, etc., were made with it. I also found that it was possible to crop in on up to half the frame on some of the teleconverter shots, to make some distance subjects still larger, a tribute to the Tiffen optics as well as the G2's resolution.

Thanks guys for your comments....Gus, it was interesting to note that the three shots, with the three different degrees of vignetting had a rather large effect on the color of the house! Obviously,I must buy the Tiffen converter to minimize "the problem".

Anybody use a 2x converter made by crystal optics. is it a good lens. The tiffen appears rather large and heavy.

Nope, I still get vignetting in all my shots, but most of the time it is negligable, and sometimes I even like it. It does depend on what aperture you're using though...the smaller the aperture (larger f/number) the less vignetting you'll get. In those occasions when I do find the vignetting a problem, like in a bright blue sky with a wide aperture, it takes 1.5-2 seconds to fix it with the rubber stamp tool or dodge tool in Photoshop. I already manually process all of my "keeper" RAW files (and enjoy doing it), so this adjustment is of no concequence to me.

Yep, I agree. I think the Tiffen Megaplus 2x is an excellent lens, and definitely worth the price. I'd have no reservations about buying the wide angle, except I don't have any more room in my camera bag. ;)

Thank you both for your opinon and your help with this.

I am going to look into buying the 2x tiffen megaplus for my G2. I need just a little bit more info if I could ask. I have a 46.5 - 52mm adapter that came with my camera and a 52mm Crystal Optics UV Filter. Are these going to be of any use to me????

What is the Correct, and best, Adapter that I need for the Tiffen 2X, for my G2???

DO I need to get a New UV filter for this and what size???

Can I leave the UV Filter on the camera all of the time, or should I not leave it on the camera???

Should I get any other Filters to help with taking good Pictures???

I do not mean to ask so many questions, but I just don't want to buy anything that would be a waste. I would like to buy the correct items the first time around if I could.

Once again, thank you for your time and information.
