Focus peaking with legacy glass?
 
I'm having a play with my EP5 coupled to a OM Zuiko 50 f1.8, but can't get focus peaking to work. Question is: should it, anyone know whether it should or not?

(I'm loosing too many grab shots with auto focus, I need a lens with aperture and focus controls, such as the OM Zuiko, to allow zone focus using depth of field. The Nokoton 17.5 f0.95 looks nice, but too expensive for my pocket. If I can get to grips with the OM50, I'll look towards a cheap 28mm, being a better focal length for street.)

Peaking needs a lens that "communicates" with the body.

I use "Magnify" and at 5X it works fine for me.

Many thanks Graham.

What legacy glass do you use, may I ask, and how do you find the results? I've read that 5.6 is the sweet spot on the 50/f1.8. If I'm happy with the 50 I may as well look for a 28, since it gets me back to where I want to be (ideally 35mm equivalent but an effective 100 is too long for street work).
Thanks again.

Focus peaking works ok on my EM10; just tried it on mine with OM 50/f1.8 and cheapo adapter at f1.8. Maybe set up differently on the EP5??

To get it to work with my Sigma 105 I assigned it to a button which I need to push to get it work but I dont use it much. Thats on the E-M1.

I use a 24mm (considered by many to be one of the best OMs to use on the E-Series) Also I have an 80mm on the OM Bellows Unit, a Sigma 400mm and 600mm CAT that get occasional use.

From what I've seen posted above, I'll have to try some different setups to see if I can get it to work.

Thanks for that, I have it working now having assigned peaking to a function button.
Great source of info this forum :)

Which version of the 24mm is considered best Graham, the f2 or f2.8 ?

While the f/2.0s are considered the best quality range, the 24mm f/2.8 is very close when it comes to Image Quality. When being used on the smaller sensor of FT & MFT the quality is considered to be negligible difference.

Also, I tried assigning "Peeking" to a button and it works with the OM Lens :cool:


Well done "Alfbranch" !

Thanks Graham.

And yes indeed, well done Alfbranch.

I'm out tomorrow with the 'nifty-50', if iit does the business I'll be on the look out for a 24mm.

Peaking works OK on my EM1 & l original OM glass plus my Voiltlander. Certainly use it for macro & all my manual focus images

My OM 28mm is better than my OM 24mm but the 28 is mint with hardly any use while the 24mm has had a hard life. It had a motorcycle dropped on it and was submerged in Georgian Bay.

But my favourite at the moment is my Vivitar 35mm f/1.9 from the mid 70's.

Seems to be a few e-group users using legacy glass.

I wonder if the appeal is driven by cost, or from the desire to get more control back into photography. For me it's zone focusing, enabled by a proper focus ring with end stops and an aperture control, all of which can be confirmed by a simple glance at the camera.

I use my HG and SHG glass for the commercial stuff but for my personal work I went retro some time ago and use my collection of MF primes. I've always used MF for my nature work, that's why I find the threads about BIF so amusing.

It appears from the attached article that M43 cameras have quite a thick sensor stack, so one might expect better results from a longer lens.

Graham, or anyone else, if you're reading this can you comment on the performance of the OM 24mm/f2.8 compared to a longer lens which (generally) have a greater exit pupil distance ( a theoretical value).
