For what it's worth...

I did some rudimentary comparison last Saturday. I'm no scientist, but the 14mm looks to me sharper than the Canon 17-40mm at 17mm. My 17-40mm is as sharp as anything I know at near and middle distances, but it seems to fall off at longer distances.

The shots I compared were across a mile-wide river on a cool day using a 5D3 body. It was mid-afternoon in bright sunlight, and I used apertures from f/11 to f/22. Near objects (foreground) distances are comparable sharpness, but the 14mm appears better for the distant objects.

Again, these are entirely non-objective conclusions from a self-proclaimed slow learner!

Oh, and focus can be a challenge with no focus confirmation of any kind (visual or electronic). Using live view you have to manually do what the camera does with AF -- open up your aperture to view the scene, focus, and then go back to your selected aperture to take the picture. Best to review the theory on DOF, hyperfocal distance, circle of confusion, etc.

Overall, it's a beautiful lens for not much money -- and it gives us a tool for trying to get great pictures like Dustin gets!
Good points!  Thank you!

The only thing I don't like so far is that DxO automatically gives it's own interpretation of the newly uploaded image immediately.  I'd rather  it just accept the image the way I've already processed it and just let me work with NR only, not all the other options.  I'm sure it can be set up not to auto process the photos, I just haven't had a chance to dig further into it yet...

So far, I like it.  Not sure I like $199 worth...  :)
Choose the "No correction" preset - the "Preset" button is at the top right of the screen.  Also, the price isn't cheap, but they've had me hooked since their early versions, so the upgrades aren't bad - this one was $60 or $70 - but I'm scared to think about how much I've spent.

Also, some random DxO tips:
  • Set white balance first
  • Use the Curves tool to set black & white points
  • If you expose to the right (ETTR), best results are generally obtained by using Highlight Priority Medium or Strong followed by a boost to the Shadow slider (or Curves)
  • Use the HSL sliders to correct color casts - vs. auto white balance and other tools in ACR
  • Use the dust eraser like you would use the healing tool in PS
  • If you have more than 2 cores/processors, change the Preferences to match - it sets it to 2 by default
  • Shutdown any other Adobe products (especially PS and Premiere) while using it to make sure it has plenty of GPU and system RAM
  • The DxO Perspective correction is amazing but make sure you leave plenty or room around the building/object as the correction will shrink the image considerably
  • The best way to use the horizon and perspective correction is to draw the initial line / parallel lines / rectangle at "Zoom to Fit" and then zoom in to 50-100% to adjust it perfectly.  Eyeballing at "Zoom to Fit" isn't very accurate.
Thanks for the great tips Mack!  I appreciate your help.  I do have DxO ViewPoint and I like it a lot.  The new LR5 corrections aren't bad but I think ViewPoint is a bit better.  I wish they would give me the upgrade fee from the ViewPoint purchase toward the Optics Pro 9 Elite vers... That won't happen though! ha ha! 

Anyway, I really appreciate you telling me those items above, it will definitely speed up my learning curve and shorten my workflow, thank you! 

I'll likely end up with it after the trial expires.  As I mentioned, clients don't seem to pick up on the noise at all but it makes a big difference to me and I like the final results so far with the couple of images I processed... Just kind of stinks that the one version doesn't work for crop and FF... Seems like they could make it so it did!  But they are a profit center, not a charity and I get that! 

All the best! :)

The UMC appears to be the difference between the two.  Whatever they did worked.  The resolution is just stunning from this lens!
Dustin, your images are priceless as always!  You've just about sold me on this lens.  I'm not overly thrilled with my 17-40mmL like so many are, I miss my Tokina 11-16mm f/2.8 with IS from my 7D days.  Had the Tokina 16-28mm but it is a beast and something was really wrong with my copy.  So now I'm without UWA, unless you consider the 17-40mm uwa, as most do, it's just not enough for me...

Is the 14mm Rok really the exact same lens as the Samyang and the others?  Is there any difference you know between any of them?  Looking forward to placing my order soon!  Thanks for the great review!  :D

First of all, thank you!  Secondly, to my knowledge the same optical lens is rebranded and sold under all of the various other brands.  Samyang is the most well known.  If you have a chance to choose the brand, I would go with either Samyang or Rokinon, simply because they are better known and the other brands thus appear more "cheap" and might diminish resale value (although this will probably be a lens you hang on to).

I just sold my 17-40L yesterday and have no regrets.
Thanks for your feedback!  I think I'll have no regrets letting go of my 17-40mmL either... though I use it mostly for Real Estate gigs...  I may go back to a Tokina 16-28 for that if the 14mm Roki is too wide for that type of usage... I wouldn't foresee issues taking the exterior photos but not sure about interior photos with the 14mm...

After taking another look at this image, I revisited my processing and decided to bring the exposure back up closer to where I started at out of camera.  Initially I didn't like all the green reflections on the water, it just seemed to busy as I remember, the wrong type of contrast for my likings...

lifting the exposure back up, I kind of like it better now.  Odd isn't it?  Why just a couple of weeks ago, I looked at the original image and thought, yuck, too much green... Now I look back and think, my, that's too dark, too black... I'm thinking this is a happy median.  Almost back to original exposure to bring out the vivid colors and textures but not quite so much that it spoils everything..

Perhaps I should revisit older images more often! lol! 

All the best!  :)

I am not about to say pixel size is the most important factor, however I would say it is far from a "mostly irrelevant factor."

Let us not take this out of the context in which it was said. We were talking about noise and the large pixel fallacy. I also said that smaller pixels collect more information, that there are tech related factors, etc.

Ok, fair enough.
Makes sense...

I tested the new "PRIME" NR on a ISO 6400 image from my 5d2. I do not get anything that I cannot do with LR, for a few seconds. The trick in LR is to keep the chroma NR low, and apply tons of lumina NR. The overall look of the LR image - color, etc., is still better.
I tested the same image in both LR5 and Optics 9 Elite.  Side by side, I liked the Optics 9 slightly better, the transitioned image seemed just a bit smoother, butteryer... (have fun with that one all you lingual aficionados).  The LR5 image still looked a little on the posturized side, not quite has smooth, not quite satisfying for me... 

That being said, I think none of my critics, fans or clients would see any difference, somehow  they just don't notice the noise as much as I do... I'm not always pleased with the way my 5d3 handles noise, though I'm thrilled with the ISO levels that I can use and dare to go too. 

I just took some really severely noisy images last week and I'm looking forward to seeing if DxO can do anything more than LR can with them.  With LR, there are no keepers.  It'll be interesting.

One thing I'm interested in trying is to hit an image lightly with LR NR and then move it into Optics 9 to see if I can get a better finish on the NR in an image that way...

The only thing I don't like so far is that DxO automatically gives it's own interpretation of the newly uploaded image immediately.  I'd rather  it just accept the image the way I've already processed it and just let me work with NR only, not all the other options.  I'm sure it can be set up not to auto process the photos, I just haven't had a chance to dig further into it yet...

So far, I like it.  Not sure I like $199 worth...  :)

some more experimentation with the 100-400 + 1.4x ... does reasonably OK, I think  8)
That's an interesting image with the broken glass!  Did you use any NR on this one Jr?  What were your settings?

Love this one.  Amazing that at 1/1250th the wings still blur, eh?  Thanks for posting the camera settings.  That makes it that much more interesting to us camera geeks!
Thanks Rusty, at 1/1600th it froze the wings in the previous image but I really wanted to try and convey the motion, just a little bit so I decided to start stopping down the shutter speed.  1st adjustment to 1/1250 did it!  I was hoping to see some motion but not lose to much detail... Thanks again!  :)

On a monster road trip this summer, we stopped by Yellowstone and experienced one of the most amazing sunsets I've ever seen:

Beautiful   ! But where's Yogi Bear ?
Must be something in the translation Sporgon, Yogi lives in Jellystone, not Yellowstone!  ;D

Hi Richard, I mentioned previously having some DIF (Dragonfly in flight) images, here's one... I couldn't remember where I filed them!  I've recently moved and don't have my external drives set up yet, so some images I've put on my internal HD, totally forgotten! 

Anyway, I'll post others as I get a chance!

This is right after getting my 100-400mm back from Canon, very pleased with the results from Canon.  I had to set my MFA settings back to zero!  That was surprising...
