P: Lens profile for Canon G1X

You know, it's really not all that hard to make your own.

Thank you, Eric, It's really nice to hear that. Maybe for version 5 of Lightroom?

Thanks anyway for answering my prayer.

Actually, we plan to have a profile for this lens before long. Stay tuned.

Yes, I think so. Thanks!

I guess at this point it is safe to say it isn't going to happen.

Hello, I'm joining this thread about one year it started and about 2 years since superb Canon G1X came to market and we still don't have any Lens Profile with this camera.

How is it possible? Two years!

I know that I can go through "Adobe Lens Profile Creator and/or Adobe Lens Profile Downloader". I KNOW that already.

But Adobe is never going to fix this problem?

Thank you.

@hdinin: Before I purchased Viewpoint I sent a pre-sales inquiry to DXO, asking if the complete functionality of Viewpoint was included in DXO Optics Pro. I wanted to decide which product to buy, given that my main concern was optic correction capabilities. This was their answer:

"DxO ViewPoint is an independent program, so it is not inside DxO Optics Pro.
These are the main differences between DxO Optics Pro and DxO ViewPoint:
DxO ViewPoint also includes unique tools like the keystoning corrections intensity slider, full canvas availability when cropping and the loupe.
Also, while DxO Optics Pro requires a supported camera/lens module in order to correct images, DxO ViewPoint does not have that restriction."

@6178582, this is an excellent suggestion, and not only for Lightroom | ACR users who have an "unlisted" lens. There is ultimately a small fly in the ointment, at least for me.

I use Optics Pro, another, more robust, more comprehensive DxO product. Viewpoint takes one function set, the so-called perspective controls, of Optics Pro and makes them available at a much lower price, and allows you to correct one image at a time, instead of loading all the images from a session as you do in Optics Pro. Also, and this is a boon you don't mention, Viewpoint comes with two plug-ins that allow you access to the perspective controls (including the distortion correction you mention) inside Lightroom or PhotoShop. So you can make anamorphic correction and other perspective adjustments part of the regular Lightroom workflow.

The fly in the ointment for me is, although the same functionality is available in Optics Pro, the high-price version of DxO technology, the plug-ins are apparently exclusive to Viewpoint (a relatively new product). I'm trying to get this clarified with the vendor. It's hard for me to justify spending almost 25% of the original license cost for Optics Pro over and above my investment simply to be able to install these plug-ins.

It seems no matter what these developer/vendors seek ways to squeeze more money out of us users.

I recently discovered DXO Viewpoint. I have been using it for a few weeks now, and find it quite useful. On top of the usual optical fixes, It fixes one optical problem no one else does -that I know of-; they call it anamorphic correction, and it is the elongated heads towards the corners, which a very annoying distortion. I only find two issues: it is not automatic (you have to do a little fiddling), and no chroma correction. However, because it is not completely automatic, you can -and should- use any automatic corrections beforehand that you can on ACR or Lightroom, which ends up being an advantage. All in all, I find it extremely useful, and worth the money. It has become integral part of my workflow.

I also use the 5D MkII, the 5D MkIII, and now an EOS-M (an even more impressive, if advanced, version of the same kind of thinking as the G1X product strategy; not surprisingly, there are not profiles yet for the 22mm EOS-M lens--or the alternative zoom--the camera comes with, but it was just released in the past month), and the first two, of course, have profiles for all the lenses I can put on them. I've noticed, by inference, that with the G1X that probably not much is lost (but who knows until Adobe or another user who can be trusted come up with a profile) unless making critical prints of images. My only "workaround" is, in "Develop" under "Lens Corrections" select the Color tab, and toggle on "Remove Chromatic Aberration." You might also want to play with the "Defringe" settings (there are two: Purple and Green, and unless you understand these controls, just adjust the amount unless you see a definitive color to the edges of objects in high contrast areas. You'll have to view the image at 1:1 on a good sized monitor (at least 21", 22" or 23" with high definition; any higher magnification with this camera will pixellate and be meaningless. On really bad chromatic fringing you can slowly see the aberrant color disappear.

I think the G1X lens is otherwise fairly good at avoiding the usual kinds of problems, as there doesn't appear to be significant vignetting. Any visible distortion I've always found to be best removed manually anyway, no matter what the lens.

If you're a perfectionist geek, all bets are off, of course. And you'll want to take three days off to render your own lens profile anyway, under a variety of WB conditions, lighting, and several focal lengths in the zoom range. 🙂
