Canon Announces the Canon RF 14mm f/1.4L VCM

[benperrin]

Do you also own the 24-70 F2.8 by chance? I suppose the 24mm end of it should give similar results for astro, so it could be my learning ground.

Unfortunately I only own the EF version. The 14mm 1.4 VCM will only be my 3rd RF lens. I haven't tried the EF version for astro.

This is where focal-dedicated rear lens-caps would make sense!

Workarounds exist

FWIW - for those looking to shoot astro at 14 mm f/1.4 there is another option. I use a 35/1.4 and stitch. In theory, a 2x2 grid shot at 35 mm has the same FOV as a 14 mm lens. In practice, you want overlap and the ability to crop uneven edges, so a 3x3 grid does the trick.
´´´´
The downsides are more acquisition and processing effort, and parallax issues with foreground subjects. Also, if used for auroras, they can move fast so stitching is not ideal (but it can be and has been done).

Yes and no: For slow-moving and wide images that is my usual solution: the much larger opening of a 35mm lens is gathering MUCH more light compared to a 14mm lens which will give you a much better s/n ratio for the post-processing (nebula etc.). Potential parallax errors are usually no problem as you have a dark and 'natural' foreground without critical straight structures. But that method isn't practical any more when you have fast moving objects like an aurora.
Canon is relatively late with this 14mm lens (and the heavy vignette of 4 EV can be a problem for 'astro') and there are alternatives as I wrote before. And it is well known that the 'old' Canon EF UWA primes were a 'pain in the butt' concerning the image quality, especially for 'astro'.

Very nice! Where did you get those caps from?
DIY ?
I see you own the whole collection, the 14mm must certainly be on order...

This is what my search engine told me:
40 CAD, but it seems to be sold out at the moment:

There are multiple suppliers for lens cap labels, in addition to fieldmade, e.g. alphagvrd: https://alphagvrd.com/products/rear-lens-cap-focal-length-stickers
They also have camera and lens skins.

These are indeed from Field Made Co. I used the customization option to adapt the ring color - red for L lenses, crazy, no ? and grey for the other ones - and add the stabilizer info where due. And, yes, the 14mm is on preorder since Thursday

I have never had to label lenses, I always knew which lens was which, no matter how it sitting in the bag.

The VCM lenses have changed that! It's a great problem to have, I love the lenses,. I'll have 4 of them once the 14 arrrives. I do need some of these back caps in my life. I have 3D printed some, but my printer can't use the harder filaments. PLA doesn't work well for very long. I could get them made, but those would be expensive caps.

Has anyone seen lens caps that are similar? I don't want the pinch caps, I may be weird, but I have never liked them. My hands are too big to fit inside a lens hood anyway. I haven't looked hard, but sometimes the microbrands are well hidden.

Sure, I could just label them myself, but supporting people making a living in this niche is worthwile.

Lenzbuddy has custom front lens caps, from 43 to 95mm, prices from $13 to $ 20, depending on the amount of information you want on the cap.

You could also scratch the focal on the front lens. An efficient and cost saving way for all the R100 haters.

To be clear, the 14/1.4 does not take a front filter. It does have a rear gel slot. At some point, Fotodiox or someone else might make an adapter to take the salad plate sized filters like the 145mm ones I have for my TSE 17.

• Built-in support of Canon EF-to-EOS R mount adapter drop-in filters (Clear, CPL, Variable ND) plus Lens Lock/Limit, Lens Function button and Control Ring.

Am I confused by this feature then?

I see the rear snap in filter in The Digital Pictures review. Not ideal but better than no filter at all.

This refers to the fisheye zoom announced together with the 14mm

That feature applies to the 7-14mm fisheye zoom lens, not the 14/1.4 prime.

That’s a holder for cut-to-size gelatin filters. I suspect it’s the same one for the 10-24/4 but I’m not certain.

the much larger opening of a 35mm lens is gathering MUCH more light compared to a 14mm lens

Not true. The smaller opening of the 14 mm lens lets in an equal amount of light. It does so because light passes through the opening at a greater range of angles.
Think of this hypothetical experiment. Suppose you have a perfectly grey sky. Suppose you shoot two frames, one with the 35 mm and one with the 14 mm, both with the same exposure values. They will look the same. The total amount of light collected by the sensor will be the same.

The size of the entrance pupil of a 35mm at f1.4 is much larger (25mm) than the size of the entrance pupil of a 14mm at f1.4 (10mm). The larger entrance pupil collects more light.

Clarkvision has an explanation with examples.
