p.1 #1 · Laowa 100 mm macro lens on Canon R and Canon RP cameras


Canon 5DSR recognizes Laowa 100 mm macro lens as full-frame and yields up to 50 megapixel photos. However, Canon R and RP cameras recognize the Laowa 100 mm lens as a crop lens and produce at maximum 12 megapixel. Canon 100 mm L macro lens is recognized by the Canon R and RP as full-frame and yields up to 30 megapixel photos

Had hoped the Canon R would help taking photos in lowlight flower shows.
Prefer Laowa 100 mm macro to Canon 100 mm L macro lens.

Keith Cooper of Northlight says he has heard reports of above problem.
Has anyone else experienced this problem? Any solutions? Thanks.

The only thing I regret regarding mirrorless cameras is not switching to one sooner.

Maybe the problem needs to be reported to the manufacturer so that a firmware fix is then devised.

Last I checked, the Laowa 100mm macro is their first lens to have any electronic connection (which provides EXIF and aperture operation, as opposed to twiddling the ring on the lens that the camera doesn't even recognize as being there at all). A pity though that the bronze age at Laowa starts with such a hiccup.

You could try taping the contacts, to eliminate comms between the lens and camera. I prefer using a mylar anulus that fits just inside the mount, as shown below. Another way of saying "mylar anulus" is "flat ring cut from drafting sheet plastic"

You'll have to enable "shoot with no lens" in the camera settings (or whatever it's actually called).

Yes. Reported yesterday. Venus Optics (Laowa) is
in Hong Kong where they are celebrating Chinese
New Year. There may be some delay.

Thanks for response.

I was very happy to see the electronic connection especially for verifying the aperture
which of course is important in macro photography.

Thanks for your input.

Will try your idea. Thanks Mr. Colwell.

Added benefit: when inserting the mylar annulus , your camera body gets upgraded to the next higher version (Mark II -> Mark III, etc.)!

UPDATE: LAOWA 100 MM PROBLEM WITH CANON R & RP CAMERAS

Wrote to Venus Optics in February. No reply (probably due to Chinese
protests and Coronavirus).

Wrote again last week and got a reply from Venus Optics Team.
Apparently there is a defective microchip causing the problem.
They are sending me a new microchip to replace defective one.
Claim it is easy to replace and attached a manual on how to do
the replacement.

There may be hope!

Yes, please keep us informed, this lens would be a very nice addition for this summer if it can escape the 11MP mode on my RP

SECOND UPDATE AS OF MAY 17, 2020:

Received microchip and reviewed full-color "brochure-like"

manual for this specific repair. Did not succeed in repair.

One screw just fell out. Removed most screws. Unable to

remove two screws. Was not able to expose defective

microchip.

Emailed preceding problems. Laowa team member advised

me to send the lens and microchip plus loose screws to

a repair shop they recommend in Arizona. Will contact

repair shop Monday. Do not want to spend too much

repairing $449 lens. Will report back to you on progress

this week. Laowa team member also advised not sending

the lens to Hong Kong due to problems with shipping.


Meanwhile received the new Canon Rf version of this lens.

Quite pleased with its performance with Canon R camera.

Works well in low light which make its useful for photographing

at poorly lit indoor flower shows. 5Dsr camera and EF version have

worked well in bright outdoor light.

The RF version doesn't have an electronically controlled aperture, right?

The RF version not have an electronically controlled aperture.

However, for macro uses I do not find that a problem.

NEW UPDATE AS OF MAY 18, 2020:

Have requested estimate of repair from the Arizona repair shop

recommended by the Laowa Team Member.

Meanwhile bought a new Laowa 100 mm macro 2X lens for Canon

EF mount. Using the EOS EF-RF adapter with no optical components

the Canon R camera shows the new copy of the Laowa EF version lens as a

full-frame 40 megapixel lens. Apparently the new copy does NOT have the

defective microchip.

If repair estimate is too high, I will keep the old Laowa 100 mm EF mount

lens for parts.
