EOS R TECH THREAD- Its time for others who will jump into canon Mirrorless bodies

There is one way I can think of, a very powerful fill flash. The only way to overpower the sun is to bring in additional light stronger than the sun. Clearly for wildlife shooting this is exceptionally difficult as the subjects are usually a distance off and flash falloff is going to be a significant factor, but it is possible.

One can always use a Better Beamer or equivalent which will add distance but is only good for smaller critters. HSS can solve that problem but the faster the shutter the more the flash power is decreased. You would need more than one flash for that type of scene.

Depending on the flash type it can have an AF assist beam whoever this won't give you what you need as you don't want light on your subject.

This is correct

I have some shots that I shot direct on axis and I used 2 AB600's to come close to the light from the sun. This is something like F/22 + for light coming into the lens axis.....2 600ws strobes will work for portrait work

I frequently shoot into the sun. But I use strobes to do it- Example below is direct 2pm sun light behind this bridal party....2 600Ws strobes at 3/4 power each. I think SS went to 1/2500 or higher and HSS kicked in to get the shots

light behind them was metered at F/18. you can easily see the rim light from the sun in hair and on arms and fountain water

this is still not a direct into lens axis shot like Tom posted...the 2nd example is direct behind the couple but again I try to use it angled into the shot like a kicker in studio v/s shooting direct into lens axis

I think that the focus peaking feature of the R would be great for confirming focus in these situations ...... but I don't know how I would use that feature when I am holding the camera and heavy lens up to my eyeball. . It seems like focus peaking would only work, ergonomically, in situations where you have the camera on a tripod. . Unless ..... is focus peaking visible through the EVF, or only on the rear LCD? If you can see it in the viewfinder, then it would be very helpful and practical to use for this type of shooting.

Yes, it's visible in the viewfinder. All the times I've used it with my 70-200, it's been handheld. Basically, if you can physically handle manual focusing at all in a situation, you can use focus peaking.

One of the neat things is clearly seeing the plane of focus moving through the entire scene as you pull it toward you or push it away.

Has anybody noticed the files recording size limit of 4gb has changed? I formatted a 64 GB card and recorded a 4K video file of 3 minutes in clog, popped the card out and transferred to Mac. Files size appeared to be 9.03 GB in finder?

Edit. - forgot to mention firmware 1.6.

Well, the 4gb limit is because of the Windows FAT format. I'm guessing clog doesn't record in that FAT format.

Yea, i do not know, older cards i have were all formatted in the FAT file system. This card is exFAT so that is why it can do the larger files. Question in my mind really was did they change the format in firmware 1.6 to format all as exFAT? I thought in the past you had to get a 256 GB or larger card for the camera to use that file system. i do not know, i could have formatted the earlier cards in my 5DMIV also (vs the R) and why they were FAT... Oh well, just hit me as interesting as i was expecting several files on that recording, and instead i got one large one!

The file system on SDHC cards is FAT 32. On SDXC cards, the file system is exFAT. That's probably the reason that you're seeing the change. The capacity for SDXC cards is more than 32GB up to 2TB.

I'll be getting a loaner EOS R tomorrow (just for one day), with the 24-105 and EF adapter. I currently have a 5D4, so what are the major features I should be trying out? I.e. other than the obvious viewfinder differences, what should I test to see if the R will be "better" in some areas?

- Try out eye AF, or at least iTR
- Use drag AF using the rear screen to change your AF points (use quadrant perhaps, and use absolute, not relative)
- Focus peaking is fun to try out
- Pop a 1.4x or 2x on one of your long lenses and watch AF still lock at f11
- Use 5x or 10x in the EVF as you set up for a shot to check critical focus
- Burst rate is dismal so nothing there to try out, the burst rate is so slow in AI servo to almost be useless
- Play with that touch bar, but it isn't worth the real estate it takes up IMO. I could have used a few more buttons than a touch bar.
- Try an EFS lens if you have it

Not my proudest moment !

Nothing wrong with the STM version of that lens at all, it rivals others at f4-f5.6 in the same range for IQ. I use that often for group shots even. Today's 18-55 EFS kit lens is nothing like the first 5 versions of that lens at all.

I don't understand your comment. . What is wrong with the photo, or with the camera or lens in the photo? . It looks okay to me. . What is there for you to be unproud about?

Slapping that lens on a R disables over 50% of the sensor pixels, for the benefit of........ well, nothing really...

I remember when they first added IS to that lens.... forever ago!
