Manual Focus Glass

Back in the .... old days, I was weaned on MF, but then the world got lazy (or maybe the lens manufacturers discovered they could make loads of dosh persuading us to go AF) But now there are some rather good sounding MF Glass being offered for MFT. I am tempted. Who has some, and what do snappers think?

Re: Manual Focus Glass

Well if you are thinking of wide angle or fisheye then selecting the sweet spot on the aperture and setting the lens to the hyper focal distance will take care of 90% of your needs.

I often use manual focus anyway so something like the highly rated 50mm f/1.4 Olympus ZUIKO OM is well worth considering

Have fun.

Re: Manual Focus Glass

I often use legacy (and some not so legacy) MF glass on micro 4/3rds and 4/3rds. The OM Zuiko 90mm f/2 and 50mm f/2 macro lenses work very well, being easy to focus because they are bright. The OM 50mm f/1.4 is also good but I don't use it very often. More recently I have acquired a couple of Voightlander lenses in Leica M fit which give very good results on the E-M1 (they will not fit 4/3rds) being bright and sharp; the 35mm f/1.2 ASPH and the 50mm f/1.1 both came via eBay and have worked out well.

The focussing aids on the E-M1 take a lot of the strain out of manual focus and make legacy and new MF glass a more than viable proposition. There is a lot of new glass out there including some ultra bright lenses from Voigtlander specifically designed for micro 4/3rds. I don't have any of those as yet but others have posted shots from them on the forum and the results look impressive!

Cheers,

JohnGG

Re: Manual Focus Glass

I have found the Kiron 105mm very good for macro and for general use. You can get it in various legacy mounts. It does to 1:1 FF, 2:1 m4/3. I use various other legacy lenses for more specialised macro.

(Currently, I am mostly using the Oly 4/3 50mm f2 for macro, ofter with a matched TC behind it and /or high quality Achromat diopter on the front, giving up to 7:1 with m4/3 crop).

I have yet to do much with it but my Nikkor-N Auto 24mm f:2.8 Non AI is very sharp and focuses very close for s 24mm.

Re: Manual Focus Glass

I've been down this route myself but wasn't happy with the user interface, especially focusing using focus peeking and magnification, if you have to. Sold my holding.

I suggest you read about sensor stack thickness on u4/3, and consider the findings for yourself. I concluded that there's nothing to beat the native lenses designed for u4/3, that's if you can put up with AF and the lack of scale markings for distance and DoF, and a depth of field control mounted on the lens itself, ie the aperture ring.

Full aperture focusing is all very well but it is best used together with stop-down aperture via an allocated button.

Re: Manual Focus Glass

I may be wrong but I believe the OP is specifically asking about anyone with experience of manual focus lenses designed for micro 4/3rds (Voigtlander (COSINA), Kowa, Tokina, Samyang, SLR Magic Tokina etc.). However, replies so far seem to have addressed legacy lenses and general considerations of MF.

Unfortunately I don't have the necessary experience, just want to help the OP to get what he's looking for.

Regards.

Re: Manual Focus Glass

I'm not sure any of the Samyang lenses are designed for m4/3 apart from the 7.5mm fisheye. Some are designed for mirrorless systems.

They are available in m 4/3rds fit but may not necessarily have been designed specifically for m 4/3rds.

Whoops. "MF" brings out standard responses.

I have seen some New Zeiss manual lenses advertised.

THANKS PETER - that is exactly my question. There are now a lot of MF MFT lenses being advertised as per your excellent Brand list. Seems that no one here has cottoned on to them. I might try one out - but still looking for any experienced comments.

Re: Manual Focus Glass

I have the Voigtlander 17.5 f0.95. It's quite a lens really. Acceptably sharp at f0.95, very sharp at f1.2 and reaching max sharpness at f2.8. It suffers from some field curvature though so if you use it for landscape you need to be careful with focusing to get it sharp corner to corner. It gives fantastic starburst effects stopped down. For environmental portraits and shot at f0.95 or f1.2 it gives that deep OOF effect that can be hard to achieve on u43.

It's very easy to focus it on bodies with focus peaking . The focus ring is very buttery and has a long throw with zero backlash to it so it is quite a tactile pleasure to use. It's a chunky piece of kit compared to the Olympus 17/1.8 though.

I might be selling if you're interested:

Re: Manual Focus Glass

Thanks to all - again to Peter for getting the thread on track - to Harold for the hazeghi list (had seen it before but not scrolled down to the MF chart),
and Paul for the experience bit. (Paul, thanks for 'offer' but I am looking in the 25mm area).

A last question. Given no electronic connection on MF glass, what form of focus confirmation is there - apart from good eyesight via EVF???

Focus Peaking (allocate a button). It will give you the principal plane of focus.
