Default Which ext. adapter should I buy?

Hi,

I'm new here but I'm not new to the Oly gears. I've been using Oly exclusively for 3 years. I was think about a new ext. adapter. But I have a hard time to decide whether go with EC-14 or EC-20?

I like the EC-20 a lot but I was worry about the 2 F-stops loss since I took lots of pics in low light condition. BTW, I have 12-60, 50-200, 70-300 and 35-100 lenses. I will use this adapter for the 35-100 F2. Which one do you suggest? Pros and Cons?

Thanks a lot,

Jacob

Hi, Not sure if this will be of any benefit but, I've used the EC-14 with the 50-200mm NON SWD as well as the 12-60mmSWD and find that with those lenses it works quite well and I really can't see any loss of IQ. I've not tried it with the 70-300mm because frankly, I would really have to increase the ISO higher than I would like to compensate for the higher aperture settings. I don't own the 35-100mm f2 but from what I've read, cannot foresee any problems.

As for the EC-20, I don't have one at this time but have been planning on getting one as funds allow. From various reviews and posts that I read I wouldn't expect to have any problems with either the 12-60mm or the 50-200mm. I wouldn't expect any problems with the 35-100mm for that matter.. As far as the 70-300mm is concerned I would probably not buy the EC-20 if my requirements call for it to be used primarily with that lens.

If I had to do it all over again, I would have bought the EC-20 telecon.


There are a number of regulars to this forum that have the EC-20. Hopefully, they'll better answer your question.

Thank you Zig. I was really debating between the EC-14 and EC-20. Both of them are excellent adapters but is 1F vs 2F stop loss the only difference between them? I really have a hard time to make decisions

Which camera are you using?

I have seen at least one poster over at DPReview who uses an E3 and has commented about using the 70-300 with the EC20 and it focussed in good light. I have a feeling that combination won't work so well with the consumer E5xx/E6xx models. The EC20 should work with the f2 zooms and the 50-200 with any of the DSLR's Olympus makes.

If I had the 35-100 I would buy the EC20. It's an excellent extender. I use it with my E620 and 50-200 SWD and have a hard time seeing much, if any degredation of image quality. I have a folder of images I took at an air show recently where I used the 50-200+EC20 for all the action shots..

And here's another folder where I was just testing the combination outside with normal daylight subjects..

I sprinkled in one or two shots taken with the 12-60 to give an idea of the scale of the magnification when you shot the same subject at 200mm with the EC20 mounted.

Hi,

Good to have you on board.

Firstly I'm intrigued why you want to use this on the 35-100mm f2, this will give you a 70-200mm f4, you already have 50-200mm f2.8-3.5?

Next you have the 300mm range covered with the 70-300 so the only gain is going to be going for the EC-20 on the 50-200. This will give you 400mm f7.1 at the long end.

Other than that I can't really see any benefits from either option.

Hi Mark,
Great question.

I'm not speaking for the op here, but the application I can see myself using the 35-100mm f2.0 with an extender would be in low light birding as well as indoor sports and theatrical. While the 50-200mm is a great lens, the image quality of the 35-100mm is significantly better and provides a better out-of-focus background than does the 50-200mm. Also, the 35-100mm has a focus limit switch to be improve the AF speed which the 50-200mm doesn't have. The 35-100mm was also specifically designed for low light applications.

Having said all that, I think it would be wise for Jacob to further investigate his desire to use the EC-20 as I read the instruction manual that is supplied with the 35-100mm and while it doesn't state that you can't use this lens with the EC-20 it does not list it as a compatible component either:

http://www.olympusamerica.com/files/...uctions_EN.pdf

my two cents
Zig

Don't forget that as soon as you add the 2x TC you will only have f4 across the whole range so for low light the 50-200 is now brighter at every focal length. Also adding a TC will take a certain amount of image quality away from even the sharpest lens.

One thing that is good with the TC is that you can just take the 35-100 and the TC so you have the best of both worlds rather than taking the 2 lenses to get the same focal coverage and low light shooting options of f2.

Sometimes I cannot see the forest for the trees! Excellent question, Mark. He really does have all his options covered and does not need the EC20 unless as you said, he just wanted to take the 35-100 f2 and leave everything else at home.

Or to get the 400mm f7.1 option, but that's the only 2 cases I see. I personally only use a 2x TC on my 300mm f2.8 (I shoot Canon) when I'm after some birds or similar. I also use it if a friend is borrowing a camera and wants some extra range and they have the 70-200mm f2.8 on, but apart from that it's not something that comes out to play much.

Thanks for all the replies. I have both E510 and E30 camera bodies. I will use the EC for E30. I guess Mark is correct, with the 50-200 mm lens why do I need the EC-20 with 35-100? My answer to this is, the 67mm vs 77mm lens diameters. I assume that 77mm lens should give me better IQ in low light condition compare with 67mm lens. I may also use the EC-20 with the 50-200 to extended my max range to 400.

I took a lot pics for my daughter's indoor music concert which even with F2 lens, lighting is always a major concern. That's the main reason I purchased the 35-100. But the zoom range became a problem while I sit down there in the audience section. That's why I'm considering the EC-20 for my purpose, looks like I have no choice but bite the bullet and go for the $$$ 300mm F2.8
