EOS-M / Re: M5 : Heaviest Lens Safe To Mount on EF-M Flange?
« Last post by Photorex on April 28, 2017, 04:24:21 PM »
It is only a guess. But I would think that any EF or EF-S Lens mounted to the M5 which is as heavy or heavier than the body itself is only meant for stationary use and not for being mounted to the M5 during transportation.
Especially such a long lens which is not only heavy but also applies a lot of torque alone by its length.

In a Canon promotion video one can see a EF 100-400mm L IS USM II lens with 2x TC mounted to the M5, but I guess after the picture/footage was taken, the photog will not transport this combination least of all with a strap.



By the way: Canon itself gives the recommendation to use the EF-EF-M adaptor exclusively with the mounted tripod adaptor for use on tripods. So a strap should also be connected to this tripod adaptor and not to the camera mount itself.

That EF to EF-m adapter has definitely been substantially built, so given that fact I'd imagine swinging a reasonably large lens off it, and so the EF-m mount itself, would be OK.

Not that I can compete with the works of LostArk, Harry Muff, Pookie, Eldar or Viggo (just to name a few of my faves from this thread) but I still feel this one fits well with the theme:



Light: 2'x2' softbox for key at f/6.3, feathered past face, bottom edge at roughly mouth height to get softer roll off and some light under cap. 1'x5' strip box for rim at f/5.6. Speedlight with omnibounce for background at f/6.3.

Hi Alan.
I'm going to go with "to find the anoraks out here that actually knew what it meant and see if anyone would ask!" :o ::) :) :) :D

Cheers, Graham.

Why do you call yourself Skatol: = beta-methyl indole; a malodorous nitrogen compound found in feces, formed by protein decomposition in the intestines? (Skatos = Greek for sh*t).

In case you haven't realised it, Graham, CR is for anoraks: anorak = Derogatory term, most frequently directed at people who obsessively pursue hobbies which consist almost entirely of gathering information about a favourite topic, generally a fairly benign and arcane device such as a specific type of computer.
Anorak in Norwegian is a special type of outer clothing, usually something we (used to) wear while skiing in the mountains. Colours preferably red or blue. If you are really crazy, you can wear grey.

Skatol, which is the old written form, now more commonly spelled Skatthold, is a special desk, which you can lock up, in the old days it was to hide the fact that you occasionally worked, today it is to hide from your wife that you spend too much time on CR ...  ::)

EOS Bodies - For Stills / Re: Image stabilizer on or off when on a tripod?
« Last post by Mikehit on April 28, 2017, 04:01:00 PM »
I have noticed a distinct difference with my 100 f2.8L IS macro when used in macro mode so now I turn it off. I have not noticed anywhere near the same issue under other circumstances.

Right, I understand that, aside from a lens that can detect being on a tripod, theoretically, under perfect conditions, leaving IS turned on while on a tripod can induce blurriness. But in practice, does anyone really have a tripod-shot photo where they can say "Oh, it would have been great except I left IS on?"

Or, is this difference really just academic, and something that doesn't really hold up in real life? Especially, when you start to account for conditions where maybe the surface your tripod is placed on isn't totally, 100%, absolutely stable and vibration-free to begin with, in which case I would think maybe IS could help.

A wonderful example of this is astrophotography where the IS seems to jump around an awful lot on long exposures.
 
first image, IS on, second image, IS off. This is only a 1/4 second exposure, I have some examples of 15 second exposures where the bright stars draw something that looks like a Spirograph doodle as a result of accidently leaving IS on....

Software & Accessories / Re: New rear-slot ND for 11-24L available

This solution does not address CPL filters which more people would want then a 9+ stop filters. And the big elephant in the room.. Is it made so that the filter can not slip off in the camera and get buggered up in your mirror or shutters...

11-24L + CPL = SOL.  You have to go big. 

You need either the XL-sized Wonderpana or you need the NiSi setup, which both run around 180mm or so.

Lee's SW150 II simply isn't big enough for 11mm (it's 13mm-ish if memory serves) use and you have to choose between CPL or grad use -- there's neither a CPL nor a dedicated ring for a CPL for that setup, so you have to use a large square polarizer and turn the holder.

(Or you go *really* third party and get some fairly budget rapid prototyping solutions that some folks are offering.)

EOS-M / M5 : Heaviest Lens Safe To Mount on EF-M Flange?
« Last post by Fleetie on April 28, 2017, 02:55:35 PM »
Silly, I know, but...  70-200mm f/2.8L IS II ?

NOT supported from the lens, but from the body/body-strap?

Apart from the cheese-wire-through-shoulders effect, would this be likely to damage/bend the M5's lens mount/flange?

And I really need to find a better, wider strap for my M5.


Thanks.
