Re: f1.4 lens wanted for E3

I've got a Konica 50mm f1.4 converted for 4/3rds I don't use.

Re: f1.4 lens wanted for E3

Does this use a seperate convertor fixed to the lens and if so does this affect the speed or is this just Konica's version for Olympus.

Probably too short for you but I've just put my Sigma 30mm F1.4 up for sale... not sure if you are looking for purely MF or not?

Re: f1.4 lens wanted for E3

Yes thanks for the reply, but i think its a tad short .

Sounds like you want the Sigma 50mm f/1.4 Sigma 50mm

I am quite interested in this lens myself, wonder how it compare's, quality wise, with the Zuiko 50mm f/2.0.

Hi Steve

I would like to know, but its really light & speed critical for what i would like it for but i have concerns as to how the depth of field would appear on the sort of shots i have in mind. You would think if Olympus can make a 50-200 down to f2.8 a 12-60 at 1.4 would be easier.

If it's light and speed requirements you are after then the maximum aperture of f/1.4 should be OK. For DoF calculations look here: DoF calculator

I am surprised that Olympus haven't introduced any 50mm f/1.4 or even f/1.2 lenses; they produced many for the OM series. You could always consider using an OM lens and an OM to four thirds adapter but Olympus don't recommend using legacy lenses over their full aperture range, see: Compatibilities for the OM Adapter

The bayonet on Konica lenses is nearly identical to the Olympus 4/3rds one. All that's needed is the addition of a 1.5mm spacer. It's a popular conversion and the aperture isn't affected.

Re: f1.4 lens wanted for E3

If you want a quality 1.4 lens have a look at the 25mm Panasonic Leica a bit more expensive than the Sigma 30mm 1.4 but worth it. I am very pleased with mine.

Re: f1.4 lens wanted for E3

I'm gonna chirp in here, to sing the praises of the sigma 50 f1.4. I bought one a couple of weeks ago from a forum member. I can't praise it highly enough. Fantastically small DOF, with lovely surrounding bokeh. Anyone thinking of this lens would be more than happy. Stunning!

Re: f1.4 lens wanted for E3

Any details of the spacer needed for Konica lenses? I have a number sitting in a box which I could maybe bring into use.

Re: f1.4 lens wanted for E3

You need to remove the various Konica prods that poke out of the back of the lens, then fit a 1.5mm spacer that covers the flat silver face of the lens mount.. Even then the lens faces downwards unless you dismantle and rotate the lens mount.

There is someone in the US that advertises these ready made on ebay - but I just checked and his ad isn't running presently.

Some use foam rings or rubber O-rings but I have my doubts that these hold the lens absolutely parallel to the camera, so I have used copper coated pcb material. I did a web page on the subject http://www.snaar.co.uk/lenses/

I laser cut a few from perspex a year or so ago. What lenses do you want them for and if I have one I'll send it to you.
