Crop mood - WYSIWYG Edition (650D / 700D / EOS M / 100D)

This is why, especially if you already have a gimbal and focus pull system attached, cheap-o C mount lenses are the way to go.  8mm f1.6 and 16mm f1.4 sold by various vendors, such as Arducam,

I don't like any lens other than Canon EF-M 22mm f/2 STM because of the lens distortion issue of the ML system.If you shoot with the original cannon video function and with a cannon lens,the camera "knows" the lens distortion and will fix it automatically.The MLV APP has no lens distortion correcting function as far as I know,so if you want to get distortion free video,you have to use a lens with minimal distortion,that 22mm 2.0 lens has almost no distortion. CCTV lens?The idea itself is a laughable

I don't understand your reasoning here.

This presumably only applies to EF(-S) lenses used with an adapter with contacts. Such lenses used with a dumb adapter or non Canon lenses used with any adapter will show distortion in any mode. Correction can be done in post as normal, if desired.

Even then, certain types of distortion, such as moustache, are likely to affect heavily cropped capture areas less than they would an uncropped image since the flatter part of the moustache is what is cropped, meaning that one might get better results with this category of lenses/adapters in crop modes than in non-crop modes such as the Canon one.

Finally, one may like the distortion given by some lenses. My two most used wide angles are the 16-35 f4L and the Zuiko 24mm f2.8. If 24mm is wide enough for the scene, I often prefer to use the Zuiko because I find the corners produced by the Canon lens, sharp as they are and undistorted as they are, to be very distracting. They have a stretched out look that results from them being further from the image center than the adjacent image edges. They don't suffer from lens distortion but they are also very unnatural looking because of perspective distortion. The Zuiko with its mild moustache produces a much more eye-like scene.

well I actually saw VERY good photos made with c mount lenses, there are some awesome lenses, very fast like 1.2 and you will never guess that the photo was made with c-mount.. I don't really like small sensors though (or small sensor area) but you can actually get very very very good results using c-mount.. Of course there is a lot of different lenses in this category and most of them are probably very crappy. But there are some vintage Japanese lenses that can give you very expensive look with lots of bokeh and character.

Finally, one may like the distortion given by some lenses.

Exactly  I always turn off lens correction

Basically with 1x3 modes you have a lot of resolution, and you can actually make your lens corrections in post, it should look better than canon h.264 with correction made on the fly.. I never tried, but it should be so, because you have more resolution and more processing power with better algorithms (you can use adobe camera raw for example, on DNGs)

See the world as what it is!Any artifacts or distortion should be marked bad for a video capture system.You are free to use effects that not exist in nature to make your images look better for your personal taste,but a camera or a lens should always strives for the more accurate representation of the objective world.

See the world as what it is!

The world is quantum fields. Representing anything above that is a matter of what most closely resembles our experience. We can probably agree that very few people see purple fringing (although human eyes suffer from all sorts of chromatic aberrations, many of which are corrected or at least smoothed over upstream), but when we get into colour and perspective, pretty much everything is up for grabs.

Just tested Crop mood's 1x1 full resolution 14 bit lossless fps = 3 mode on 650d. Basically, this mode is not working. The script windows pops up for no reason. Also, at 3 fps AR 2.4 the calculated data flow is supposed to be around 40-50 MB/s according to ML, yet after only 1 frame recording stops. This behavior is very similar to the old version before Crop Mood.
I am redeploying my 650d to a dedicated time lapse camera, so this mode is critical to me. I am sure many other MLers like the full res 1x1 mode too. Once trying some full res 1x1 footage, I guarantee more will be addicted to it.
Thanks a lot to Bil's great work!

On the Eos M original, only peripheral illumination and chromatic aberration are corrected in camera, not geometric distortion.  However, as other have pointed out, using 1x1 and being cropped in on the sensor makes the best use of the less distorted center of the image circle.

CCTV lens?The idea itself is a laughable

I humbly submit a posting of a video I made earlier this year using a danne build. 

https://www.magiclantern.fm/forum/index.php?topic=26758.0

It’s 2520x1080, shot variously either stopped down or, once it gets dark, wide open.  You may judge the level of distortion, but for a $70 USD lens it would be far more laughable to try and put a hulking piece of glass like a sigma 16mm f1.4 m mount on, or even a viltrox or something for several times the price.  I tell you, it’s a gimballer’s dream lens.  Some CCTV lenses do have bad distortion, but you can usually check a data sheet ahead of time.

Have you tried turning sound recording off before recording? The way Bilal stated it in the first post suggests that no sound will be recorded when using that mode, but for it to work, you actually need to turn sound recording off.

Is it possible to have L/R buttons change shutter speed ? I use manual lenses so it makes more sense to have Up/down buttons change ISO and have L/R buttons change shutter since those two are only things we can control with manual lenses.

See the world as what it is!

That's not for me, it will be so boring... I will never pick up a camera that just records 1:1 everything as you see it.. 
Why everyone loves film for example? Maybe not everyone but a lot of people..

My favorite lens is Jupiter-21m and this is just the opposite side of what our eyes can see. I love magic that camera can give us. I love anamorphic lenses with all their unusual distortions, flares, depth of field and everything.. It is just so beautiful

I don't know guys, everyone can do whatever they want of course.. For example painters, some of them do hyperrealism but it is often considered... let's say not as much of an art, because any camera can do that now And you should express your soul and your unique vision through the art. Or maybe not, art is a very broad term and can go in any direction.

So it is your job to select camera/lens combination so it will suit your ideas and creative process, maybe you want to show the world exactly as it is, maybe not

The EF-M 22mm is undoubtedly a very good lens but get your facts straight: MLVApp is the culprit because it does have lens correction profiles (CA + distortion + vignetting), which are automatically applied, recognized and cannot be toggled off. If you want to deactivate those you'd have to grade using CinemaDNGs inside RawTherapee/Lightroom/CameraRAW/etc.

Besides, any decent CCTV or industrial lens is on par if not superior to the EF-M kit lenses (uncorrected). They have wider fields of view on both Canon's (x1.66) and Bilal's/Danne's various crop factors and way, way faster apertures (i.e f/0.95 25mm Schneider-Kreuznach's Xenon). Not to mention the vast selection of other adapted C-mount lenses that were meant for video/photo/Bolex/whatever (Angénieux, Berthiot, Wollensack etc). Heck, even some properly adapted D-mount lenses are just as good if you can achieve infinity focus.

The only true downside to all those manual lenses is the lack of stabilization.

[eardrumfilms]

Are the 100D focus pixels maps already available for MLVapp? If they aren't yet, is there any way we users with a 100d but without coding skills can help making them?

PD: probably there are other forums where we can debate about lenses, optical distortion and the nature of reality. The Crop Mood ML build is something complex and interesting enough and this thread used to be a great source of information.

You open with "get your facts straight" then end with an opionionated rant about "the superior quality of CCTV lens" ?  How about posting some charts or citing reputable sources that your analysis is based on?
