  • Olympus/Zuiko 70 to 300mm

    I have been contemplating buying a Optika 500mm mirror lens, but not to worry after careful consideration i thought "its not the lens for me".
    Instead i shall wait a little longer and get the Zuiko 70 to 300mm lens from Amazon at just under 300.00, and after a few weeks get the EX 25 at 150.00, by far a cheaper way of getting a large lens, and with the EX 25 doubling the focal length of the lens, it takes it to 600mm, more than enough for what i need.
    Now has anyone had experience with the Zuiko lens, and this combination, i would be very interested to find out.

    Always been a bit confused about extension tubes but

    1) I don't think they effectively double the focal length

    but

    2) they do reduce the minimum focussing distance - thus making things bigger because they are closer,

    I've always understood this comes at the expense of being able to focus at far away objects.

    So I'm not sure they will make a usable 'long' lens out of the 70-300.

    Come the morning I'm sure Ian or another 'grown up' photographer will clarify, but I wouldn't push one-click ordering till then.

      Hi Paul

      I'm afraid it doesn't quite work that way. To get double the focal length with all the trimmings, you will need the EC20, not the EX25. The EC20 is a x2 converter and will make your 70-300mm effectively operate as a 140-600mm.

      I must add though, that the 70-300 is not the fastest lens in the world, and though I swear by it, and have achieved decent results with it, it is not the best lens upon which to use the EC20. I wouldn't use it with this, as you'll lose two full stops of light.

      I use the EC14, a x1.4 teleconverter with this lens, making it a super 98-420mm lens.

      Unfortunately, there's no cheap way to get a decent lens, at 600mm...!

        You might look out for a Tamron 500mm f8 mirror lens or its smaller sister the Tamron 350mm f5.6 mirror on ebay. These seem to go for 80 to 100. If you get a Tamron Adaptall - 4/3 adapter you can use this and many other nice Tamron lenses...

        However I will say you always see these 500mm lenses for sale. There must be a reason - too long to hand hold? doughnut shaped bokeh? People seem to buy them, try them then sell them.

        Good luck with your search. Whatever you decide on, don't be tempted to buy a cheap 2x teleconverter. The Olympus EC14 and EC20 are very expensive for a reason

          Re: Olympus/Zuiko 70 to 300mm

          I had a 500mm mirror lens many years ago, and never got one decent picture from it! A few arguments against then...

          1. They are generally too long for working hand-held despite being compact and light which tempts you to do it!
          2. Fixed aperture (usually f/8 or nothing!)
          3. Low contrast - not too sure about this in general but mine was hopeless
          4. Doughnut-shaped out of focus highlights (not necessarily a problem, maybe a mater of taste)
          5. Using filters is difficult

          Eventually I traded mine in for a wide-angle lens!

          Also beware 2x converters - even the Oly one. You will lose two full stops of effective aperture. With a 1.4x you only lose one stop.

            Re: Olympus/Zuiko 70 to 300mm

            I have had promising initial results with a 200mm (fixed focus) f4 legacy OM lens, cost about 45 on Ebay, (incl p & p). It is a reassuringly solid lump of metal and glass.

            It has, of course, significantly more reach than the kit 40-150mm, and appears to offer similar resolution.

            The only problem was that it proved too heavy for the first adapter ring I bought (some 6 again on Ebay), quickly inducing a wobble and then not focussing properly, but it seems fine with a better one.

            I've tried it with a 2 x 1 Vivitar converter (by courtesy of Ellie) and the reach is spectacular, (equivalent to 800mm on full frame) but the maximum aperture is f8, although adjustable.

            This could be a way to go - without breaking the bank - if you don't mind not having a zoom (in theory better quality without) and being limited to aperture priority.

              My experience with old 35mm lenses is that whilst they may be reasonably sharp, the contrast is lower than the digital Zuikos.

                A big thanks for the reply Nick.
                Again i checked the write up on Amazon, and it seems you are correct in what you say.
                It states that it doubles the magnification, and not the focal length of the lens, how this would effect objects in the distance i am not sure, but as you say the members in the know will eventually give us an answer.

                  Thanks John for the info.
                  I will have a good look around for that EC14 that you suggested as the size it converts the lens to 98-420 is plenty big enough for what i want.
                  All i want it for is local wildlife in and around our parks, Deer, squirrels, birds, etc, and i don't want to spend extortionate amounts of money for a large lens, this will work for me.

                    I thank you Pete for your reply to this thread.

                    I can imaging that the expensive equipment is in general built to a high quality standard, you only get what you pay for.
                    There is a saying that goes "buy cheap, buy twice", and that goes for almost every product, so i will play the waiting game and get the best i can possibly afford.

                      Thanks Steve, i will bear this in mind when choosing any equipment i buy, but the mirror lens is definitely a no go, to many bad reports to take a chance on maybe getting a good one, not only that i find with my arthritis in my hands manual focusing would be rather tricky for me.
                      So i am going to stick to what i have been advised to stick to, and not deviate from the plan!.

                        The best of it is David, i had a chance of a Sigma 40 to 200mm a few weeks ago for just 67.00, and i let it go , well i think it started from 40mm but it definitely went to 200mm.
                        I should have snapped it up, but i thought there was not lot of difference between 150mm and 200 in reach, so i did not bother to buy it.
                        but then again with a teleconverter that lens would have been big enough for wildlife.

                          i want to steer clear of OM lens as they are manual focus, but it has to be a digital lens for me.

                            Sounds like it was a Sigma 55-200, which is not a lens I'd recommend.

                              Is there any particular reason that this lens is not that good ?, i would be interested to find out!.
                              Now that you have said its a bit iffy, i am glad i did not get it or it would have been a total waste of money.
