As it seems to be the trend these days with Canon, a budget lens has been released where distortion correction can't be disabled in camera and is forced on. I took this new little lens on a beautiful hike today and took a few sample shots with it - I was primarily there to unwind and capture some wildlife with my Fuji X-T4. I took several shots and was honestly surprised how it appeared to be performing (my good experience with the forced correction RF 14-35 fresh on the back of my mind). When I got back into the car I "pixel peeped" the corners pretty hard and identified some fuzziness of the fine details even stopped down quite a bit. This indicated to me that there was certainly some mischievous amounts of corrections being applied to these images. Boy...I had not idea just how incredible discovery awaited me back on my computer.
So I'm just going to post these photos as I could best match the "cut off point" for the corrections. Please keep in mind that the JPEGs coming out of the camera are indeed 45mp. However, you can see from these examples that Canon is providing some bombastic corrections to the photo. I've reduced the JPEG size to best illustrate where the corners of the final image actually begin and overlaid them on an uncorrected SOOC RAW file. There is a lot of software stretching going on here to make the image work. The lens is more of a 14mm that is essentially pulled into shape by the camera. On the RF 14-35, the final image looks absolutely magnificent and if we didn't know it was going on, we wouldn't have suspected any Tomfoolery as afoot.
As a side note, the lens works magnificent for video and I believe that was the entire basis for the creation of this lens. As a photo lens...just don't expect much in the way of fine detail in the corners unless you crop it down further to 17 or 18mm. The final images look pretty decent and I don't want to draw too much negativity toward this lens, but it's worth noting that corrections are once again essential to the use of RAW images. Canon and Adobe need to sit down and talk about releasing firmware updates accordingly because here we are over a month later and the RF 14-35mm f/4L IS USM isn't supported. I already dished out $1700 and created my own profiles for 14mm and 16mm, but I need the REAL correction profiles for these lenses to use them professionally. If Canon doesn't come up with a profile for the 14-35 by the end of the year I will be selling it.
