After some of my playing today, I have a question about this. I set the focal length to 200mm for my adapted lens, but then when I switched back to my native lenses, this did not automatically update in the camera settings which seems entirely wrong to me. There is no "auto" setting that I can find. If I hook up a native lens, does this setting cease to matter and get set properly by the camera or am I expected to change this manually every time I switch a lens??Olympus cameras are well-suited to using adapted lenses as their image stabilisation (IS) is sensor mounted, however for this to be effective you will need to set the focal length of the adapted lens in the menus. Don't apply any crop factors: if the lens is 24mm then set the IS to 24mm.
The 4/3 adapters are for 4/3 SLRs, not m4/3 mirrorless cameras. They would fit your camera if you already had a separate adapter for 4/3 lenses.
I do the same thing, but know exactly why I prefer it. Besides of course the fact that I have actual Four-Thirds lenses which I use, the Four-Thirds mount adapter also allows me to use Four-Thirds teleconverters like the excellent Olympus EC-14 and EC-20. Or the 25mm extension tube as well. Since Four-Thirds has the shortest flange distance of all SLRs (that I know of, and not including Pen F), all other SLR lenses can be adapted so I can use the same high-quality teleconverter on each (at over $550 for a converter, that puts it to much better use!). Also, since most of my commercial lenses are Four-Thirds, if I adapt all my legacy (SLR) glass to Four-Thirds then it allows me to keep the Four-Thirds adapter on my camera so that I can swap between legacy and digital easily.Yes, some how i prefered to adapt through 4/3+MMF2 adapter rather than direct, besides i find it to thick also might wanna consider to had another 4/3 DSLR body again someday
I am so envious of the scientific mind. :tongue:The sensor diagonal of full-frame digital is 43.3mm and for the m4/3 sensor it is 21.6mm, which is about as close to 2x as you can get. The Canon APS-C sensor uses a 1.6x multiplier to calculate equivalent focal lengths.
Technically the macro ratio shouldn't be converted because the macro ratio refers to the size of the object and the size of the projected image on the focal plane, although it is true that a smaller sensor will record an object larger than a larger sensor will if the final images are printed at the same size.
This remind me last Sunday, when I had my e3 upgrade firmware from 1.0 to 1.4, its also mention about this is.Paul A said:Hi,
So it seems using legacy glass with m43 may becoming more popular. Great.
How/what do you set the focal length(s) for the IS/Info setting when using lenses(focal lenths) that do not conform with Oly's preset choices?
ie. I'd like to use a 57mm 1.2 but my EM-5_IS_Info...does not have a 57mm setting/choice.
iirc the choices for using 50mm FL(s) range are 50mm and 55mm.
I'm assuming go to the closest neighbor (and how are the IQ results with that route) or better yet turn off IS (which of course[acccording to manual] is not entirely possible with EM-5)
All you can do is choose the closest focal length to that of the lens you are using. At 57mm, you're only out by a few percentage points if you choose 55mm.I'm assuming go to the closest neighbor (and how are the IQ results with that route) or better yet turn off IS (which of course[acccording to manual] is not entirely possible with EM-5)
