    Default The 1.4 & 2.0 Teleconverters

    Well I have begun putting together some notes on the teleconverters. For the next magazine it would be to large, for that format. So here is the first part on the sharpness of the teleconverters. http://www.fourthirdsphoto.com/teleconverters/

    Thanks, Tony! This will be very helpful to me in making a decision between the two TC's.

    I picked up the EC-14 a couple weeks ago to use with the 70-300 and am getting mixed results. Macros with a tripod are absolutely fantastic, but when there is a greater distance (hundreds of feet) between the lens and subject, it seems like sharpness is somewhat compromised more than i had hoped. Plus, at the long end, the lens is not really fast enough to compensate at all for lens shake or quick subject movement... focus hunting is standard with the L1 in all but the best light. I sort of figured this was what I'd get, and look forward to having one of the faster mid grade or pro lenses to use with the EC-14; that said I don't know of anyone shooting with a different dslr system that is reaching an 850mm fov with a setup as small and manageable as mine. Some of the macros I have achieved from one meter with 70-300 + EC-14 are truly breathtakingly sharp.
    All that I share with you is purely my personal perspective based on my own experiences. Feel free to constructively criticize my opinions and my photos, please!

    Could you please elaborate what you mean by "sloppy" in your evaluation:
    " All in all the most sloppy lens and teleconverter combo was the 50-200mm and the 2.0 teleconverter.

    thanks for putting this together

    whilst it's well presented and I don't doubt the accuracy etc I found the resultant images confusing in a number of cases

    surprisingly poor

    50-200 @147

    90-250 a couple of times

    amazing

    70-300 @ 150

    as expected

    150 @ 150

    and most of these are without the TCs...

    overall as presented the results seem to suggest that not only can't you generalise about either of the TCs but that you need to be specific about the focal length of a particular lens and tc combination.

    and all this before apertures are bought into play!

    I have both TCs and absolutley agree with your point that useability in normal practical environments is the biggest factor in results with different combinations.

    thanks,
    The sloppy comment is when the 50-200 is on the tripod, and than you have a teleconverter between it and the body, their is quite a bit of movement between the body and the lens. I couldn't think of any other word than Slop. You will notice a little with the 1.4 tc, but with the 2.0 tc its a lot.

    Thanks for this report.
    I have been using the 50-200SWD for about a month now and I am very impressed.
    This morning I shot some pictures of flowers and bees with excellent results. I now prefer this lens over my 14-54 for close ups. The larger working distance is more to my liking, especially when shooting bees!
    Just today, even before I read your new report, I ordered the EC-14.

    Tony,
    Do you think you could handhold the 150 with the 2.0 tele and get acceptable results? Because if you can't then I surely can't.

    Oh yea, I hand hold most the lenses, even the 90-250 when I must. Good technique is important though. But with the 2x tele on the 150 its going to be softer than without it. For a 2 teleconverter it isn't too bad on any lens. (Compared to the 2x teleconverters on the market that I have used) Really the 150mm is quite a light lens. Get sufficient shutter speeds and you should be fine.

    Thanks for your quick reply. I'm going to be using the 150/f2 for marching band shots during halftime shows. Night shots and most likely bad stadium lighting. I have the 1.4 tc and was wondering if it's worth the money to upgrade to the 2.0 tc. I'l be using the E3 with the combo. I'm leaning towards not upgrading at this point since I'm not sure the extra reach is worth the loss of a stop. Decisions, decisions.

    You can try - Get you shutter up to 1/160 - 1/180 - Monopod would be best but any slower than that and you will probably get subject movement. That would probably be dragging the bottom of usefulness. (OF course a flash you can go slower)
    The kids should be stopped around their, they arn't moving to quick.
    Also you will be at 300mm - so with IS on you can in theory hand hold at that speed.

    So Can you in your stadium get - 1/180 f4 and still only be at ISO 2000? Maybe???? Depends on the stadium I would guess. (And I could be wrong about shutter speeds, you may need much faster - that above would be a starting point to stop subject movement)

    I'm having a difficult time using the 50-200 SWD / EC-14 combination and getting focused images on my L1 even with shutter speed of 1/1000, even 1/2000. Some appear to be due to shallow dof, some due to motion blur... man it ain't near as easy as the 70-300 was wide open at the long end even hand held! Am I experiencing one of the 4/3 consortium niggles due to my L1 perhaps? Is the added weight of the 50-200 enough to throw off my technique? I'm not happy so far with 50-200/EC-14... (with an L1)

    Maybe I should start a new thread for this because I also now own an L1. I saw an offer I could not refuse. What I've been thinking is that at the shutter speeds I will need for the shows, IS might not make any difference. I have lots to say so I will start an L1 thread. See you there.

    This probably isn't much help, but the standard 50-200+EC14+E-510 works very well, even handheld. I can only imagine the SWD version would be better.

    Guess #1 is you're missing out on IS; Guess #2 is the L1's autofocus isn't happy with the lens combination. Have you done careful testing on a tripod?

    I don't have a Guess #3

    Yea their are a lot of things that can be wrong in your senario -In addition to the ones listed above. The surfers are quite a ways from you. We have atmospheric (which is a HUGE effect during the summer) Think the vapors from the beach which are created, the issue of mist in the water.

    Probably best to start an example thread in discussion.

    My experiences are that all my lenses work very well with the 1.4x, but only the f2 lenses work well with the 2x. I think the biggest issue with using the 2x with the 90-250mm,especially at the far end, is that the smallest of visbrations will be significantly magnified.

    Cheers

    This photo and the next one are from my experimenting today handheld using the L1, 50-200 swd and 1.4 tc. On the second shot there was no time to actually focus, I just did the best I could. I guess tomorrow I'll try to up the shutter even more. I realize they are the opposite of what your trying to shoot. I could not have gotten these with the E3. The shutter takes me too long to press. At least being able to get them leaves me hope to improve compared to not getting them at all.

    I am also getting spectacular results in macro and near range targets. It is the longer distance subjects *in motion* that are eluding my focus ability. I'll post some samples in another thread for discussion.

    Thanks Tony,

    This comparison was most helpful. The 90-250 and 150 f/2 lenses are what interested me. I'm not at all surprised they performed so well. Suprisingly you mentioned the 70-300 quto focused @ f/11. I wonder if the 40-150 would do it as well? I guess I'll have to buy a teleconverter and find out!

    As an underwater photographer I have been waiting (about 2 1/2 years now) patiently for the announced 100 mm macro to arrive. With the introduction of the EC-20 2X tele converter I have been able to get an idea of what the lens will do.

    E-3, 50 macro, 2X tele converter, SeaTool housing, Athena macro port and extension, Athena ring flash.

    Thumbs up Re: The 1.4 & 2.0 Teleconverters

    For quality assessment of the combo Olympus 150mm/2.0 + Olympus 1.4x teleconverter please refer to this link to DIWA Lab; the 150 mm/F2.0 comes out as the very best lens ever tested by DIWA Labs per March 2008:

    http://www.diwa-labs.com/wip4/compar....epl?id=216151

    Exerpts:
    Our test (DIWA Labs using DxO Analyzer 3.1) of Zuiko Digital ED 150mm f/2 confirms Olympus' statement of the E-System super pro lenses being the very best available for digital photography as of today. During my 24 years of testing cameras and lenses, I have never seen the like of an objective of this family (comp. to 300 mm f/2; 35mm format) that exhibit this class of optics. Despite the extremely fast aperture, the compact size and light weight, the test results show the lens to perform flawlessly. Even using the teleconverter EC-14 (equals. 424 mm f/2,8; 35mm format) the results are exeptionally good (in Norwegian).

    I gave up and may and in light of recent announcements by Olympus I don't see this lens hitting the market. You may have to settle for Sigma's 105 f/2.8.

    The Sigma lens is not idle for an underwater photographer for two reasons, slow AF speed compared to the 50 macro and more important the shift between AF and manual focus requires that you move the focusing ring forward and back. I have a gear to turn the manual focus ring which I use about 10% of the time but no gear will move the ring forward and back.
