Title: I should really not be allowed out unsupervised by a responsible adult
Post by: Viv on September 11, 2018, 09:30:05
I was thinking about buying a Fuji X-H1 or Fuji XT-3.
But ... there was a rare vacant parking space outside my local Leica agent, so ........
I bought a Leica Q.
35 mm sensor (what some people call full-frame), 24MP, fixed 28 mm f./1.7 lens.

Congrats!  Now that you have the camera, please post, not in a hurry, some images taken with it!

Congratulations!

a clear argument for dealers to provide comfortable parking choices in front of their shops ;-)





(I generally disregard car driving altogether, but I see that in certain situations no other option makes sense, like in certain US cities...)

Spur-of-the-moment purchases often have been lying patiently and latent waiting to be effectuated. So don't resist the urge.

Congratulations. We look forward to results.

A quick snapshot shows that the Leica lens hood cuts the corners of the frame.

Not good!

Hacksaw, Dremel?  :(

Or wrong lens hood? ;D
Title: Re: I should really not be allowed out unsupervised by a responsible adult
Post by: Viv on September 11, 2018, 14:53:19
It's the right lens hood. Supplied with the camera. Fitted correctly.

Hacksaw then...  ;)

Is this from a raw file, processed with a converter that does not compensate for the rather significant distortion of the 28mm lens??
Title: Re: I should really not be allowed out unsupervised by a responsible adult
Post by: Viv on September 11, 2018, 16:07:48
Yes. RAW file processed with Photo Ninja.

As soon as you remove the barrel distortion they are gone, a little homework on the camera will tell you a lot about the camera. LEICA User form for instance;)

Have you added a filter ? The extra thickness may induce vignetting.

This is by design!


Old news !


The camera firmware adjust the file for you,,,


Don’t shoot raw if you don’t know how to process the file ;)

The barrel distortion seems to be pretty pronounced.  The lens could be designed with the premise of the digital correction.

Yes, it is very pronounced. Correct it in post and the vignetting is gone.

That's automatic for me shooting Nikon, no matter the lens, and LR makes it easy as long as the lens is in it's database.

ACR has supported Leica Q since the version 9.1.1:

The corners are fine when shooting jpg.

The Barrel Distortion Correction tool in Photo Ninja does not cure the problem when processing the RAW file.

It seems the camera is not supported by Photo Ninja.

Could you post the JPEG (straight out of the camera, just resized)?

The angle of view should be significantly different from that of the RAW image posted initially.
Title: Re: I should really not be allowed out unsupervised by a responsible adult
Post by: Viv on September 11, 2018, 17:02:07
Nope. That image exists only in RAW.

for those who want to play with this significant (barrel) distortion: some Leica Q raw files can be found at: https://www.photographyblog.com/previews/leica_q_typ_116_photos/

Post by: Eddie Draaisma on September 11, 2018, 17:18:55
Correcting the distortion of the Leica Q files sometimes leads to visibly less sharp corners. Not exactly my cup of tea. Didn't the shop have a nice M10 with e.g. a 35mm Summilux in stock??  ;)

Post by: Birna Rørslett on September 11, 2018, 17:24:47
The recent incarnation of Photo Ninja deals easily with the Leica Q DNG format as such. However, one has to do a manual distortion correction if it is desired to get rid of the dark corners.

Thanks. I do not have the latest version.

Will investigate.

Yes. I just tried it and it works.
Thank you for your help.
