Take one Olymopus E-M10.
Start with the "kits" lens' 14-42mm and 40-150mm.
They work and get some good pictures.
Add the 25mm f1.8, now that is a step up in sharpness and just a better picture.
Add the 45mm f1.8 and the results again move onto another level, that has become the goto lens.
There are lots of desirable lens' but costs sky rockt quickly so the wishlist remains unfulfilled and tthe 60mm macro, 12mm f1.2, 75mm f1.2 and any of the new pro range remain in the shops.
But all is not lost.
A pair of extension tubes (10mm &16mm from "Meke" on Amazon, something like 30) produces good macro results, pleased with that, another set added good make for some interesting results.
Today a step further.
I read a article (I don't have the link, it was on an RSS feed and it took a few days for the content to percolate through) about connecting an old Canon lens to a body and getting some impressive results. Again a trip to Amazon to find that a cheap and cheerful OM to M4/3 converter is 6.99.
3 days later...my uncle's old Soligor 500mm mirror lens is strapped to the front of the camera, it is rather large and most certainly the part that needs a tripod.
Here is the scene taken with the 25mm lens.
Photos are duly taken, focussing is much harder and there is a noticeable wind in the garden today which does little to assist. The Oly's 2x magnification helps little with focus because the wind effect is magnified close up.
Here is the same picture with the 500mm mirror lens.
Ok so there must be a loss of focal length because the converter is essentially the same bit of kit as a macro tube (must try that!) but with a 500mm lens attached to a 2x crop factor camera I have something like 1000mm of lens and I am thinking moon photos.
Returning indoors to the bag of camera bits to find an end cap to discover an OM2x converter, so 2000mm is looking good.
Here is the same picture taken with the 2x converter and the 500mm lens, I gave up attempting to focus a this point.
Lastly, just to test I attached my dad's 50mm OM f1.8 zuiko lens and took the same shot again.
As I understand it you have found an adaptor to allow the use of OM bayonet lenses on your digital camera? I still have various OM bayonet lenses here, but Len's gone missing.
ReplyDeleteIn the picture you include taken with the OM 50mm f1.8 is that vignetting or a depth of field issue on the grass?
The picture with the 50mm was taken at f1.8 so depth of field is what causes that effective.
ReplyDeleteThe converter is this https://www.amazon.co.uk/gp/product/B008H2HZ7O and seems reasonable to expect a converter for pretty much anything to anything else.
After much experimentation on what are cold and dark evenings I have established that the lens cannot take photos focused on infinity. Further testing and tinkering has shown that the focal range shown on various lens doesn't match the real world (so the 50mm f1.8 shows infinity at somewhere less than the 10m mark) and indeed any of the lens longer than 50mm seem to be incapable of infinity focusing. My suspicion is specifically that the machining of the particular OM to M4/3 adapter I have is ever so slightly out (too big / too small by not much!).
ReplyDeleteHaving read numerous articles it appears to be a common issue and this particular device is supposed to be capable so it may only have been tested on short focal lengths or the manufacturing tolerances may vary. The only solution appears to be testing on a reputable manufacturer device .... at a lot higher cost, just rummaging on the Park Camera's website to see if they see such things.
