Hi Guys, i live in UK very wet country and from about year my lovely lens getting some issues ,i get foggy pictures, sometimes front element sometimes rear or filter element got condensation ,is there anything i can do about it ,is this is normal ?

Thanks for any help anyone can provide on what I know is a fairly obscure question. Canon USA support has been unable to provide guidance.

The Canon EF 500mm IS L II appears to have a feature in its image stabilization algorithm that detects when the lens is mounted to a tripod or otherwise very stable and thus turns itself off to prevent the subtle movements that result from IS. From what I understand this behavior is also present on other Gen II supertelephotos, and I've also seen a post describing this in the newer RF 100-500. This behavior is independent of the IS "mode switch" setting.

unfortunately the IS can be slow to kick back in when it is needed (start panning, wind gust etc), and this results in shaky footage when using the lens in video applications. The correct approach for filming with this lens (and other long lenses for wildlife) would be to turn IS off entirely, secure the lens to a robust rail system, and then put that on a 40-50 lb fluid head + tripod. That's a lot of camera support to hike into remote places with however, and right now I use a Sachtler Ace XL w/ CF legs and mid-level spreader (~8 lbs).

I'm almost certain this behavior is a feature and not a bug, I have seen it in a couple different copies of the 500 II. There are some mentions around the web of this as well, but unfortunately nothing in Canon's official documentation and so canon support refuses to acknowledge it.

Can anyone provide guidance on how they have used the canon supertelephotos to produce stabilized footage? Thanks!

Hi folks, this topic might be related to another thread in regard to R cameras freezing up.

I have quiet a large lens collection, only two of them are RF Lenses all others are EF lenses.

A big part of my collection are lenses 10 to 30 years old and I happily torture my new R7 with them to find out how they behave.

As some might know I use not only the Canon EF to R adapter but also a Viltrox Speed booster. The phenomenon I report happens on both but here I talk only about the Canon adapter.

With some lenses my camera locks up or after a few minutes of perfect behavior the AF start to stutter. Drove me mad so I started to investigate.

Factors I excluded first:

• The Canon adapter (the Vilcrox also) is sound engineered, no wobbling, so the connection between the contacts should not be an issue.
• I skipped lenses with dodgy protocol implementation like Tamron 35-105 2.8 (1994) or several Sigma fisheyes (1992-1998)
• I skipped lenses with enormous energy consumption which already have proven to lock up my EOS 5dMK3 and EOS 1dxMK2 (Sigma Lenses again)

All issues with AF stutter or camera freezing up or the “some error occurred, restart your camera” disappeared once I cleaned the lens contacts.

So I excluded Lenses which work so far flawless but which have wear and tear on the contacts because of being mounted 1000 of times in 30 years (Tokina ATX 28-70 2.8, Canon 20-200 2.8 L, Canon 400 2.8 L and Canon 85 1.2 L)

Again: all errors done after swiping the contacts

Now that sounds like a pretty simple explanation…. But it isn’t.

I clean my front and back elements and sensors whenever they are dirty. I also clean the lens contacts when I buy a used lens. But cleaning the contacts is usually not necessary. I have frequently used and changed lenses that I have never cleaned or not cleaned for maybe 15 years. Those lenses worked on the analog EOS 10, on the EOS 30d, on the EOS M and now on the R they show issues. So if a dirty contact seems to be the issue, previous EOS models could not be bothered to fail.

So my question is how many factors have changed in the evolution of the Canon bayonet?

Of course there are more contacts now, but the lenses in question don’t have them.

Is an R camera relying on contacts in existence since the first EOS but which never have been critical before? Do they read a contact which before just transferred juice? Did they change protocol, voltage or frequency?

I do not know enough to make a guess, but for my issues cleaning helps and that means from now on my after use lens care routine gets enriched by a swipe of the contacts.

Still I would like to know whats the driver behind. Maybe the more technical people here can make an educated guess or shed some light?

One of the more popular “big white lenses” from Canon was the EF 200-400mm f/4L IS 1.4x. It was never a reach to assume Canon would make an RF follow-up to that lens. It also shouldn’t surprise anyone that Canon would do a redesign of the lens instead of a simply modifying the existing design

Dear Colleagues:

I will be on a Southern African Safari this summer and am curious on what combination of RF lenses one would recommend. I am limited in weight due to travel restrictions. In addiiton, I and am recovering from an ankle sprain so depending on how the ankle feels in six months I might want to go lighter as well.

Some combinations I am considering:

Combo 1: (net weight = 12.14 lbs)

1) Canon 24-105 mm f4 1.54 lbs
2) Canon 100-500 mm f4.5-7.1 3.00 lbs
3) Canon 400 mm f2.8 with 1.4x and 2.0x TCs (6.4 lbs + 1.2 lbs)

Advantage: I cover all focal ranges from 24-800 mm so should work well for birds as well as larger mammals.
Disadvantage: Heavy to carry and if using the 400 mm f2.8 I would likely be changing TCs in the field under (very) dusty conditions which is not ideal.

Combo 2: (net weight = 7.8- 8.24 lbs)

1) Canon 24-70 mm f2.8 1.98 lbs or Canon 24-105 mm f4 1.54 lbs)
2) Canon 70-200 mm f2.8 3.26 lbs
3) Canon 100-500 mm f4.5-7.1 3 lbs

Advantages: Significantly lighter than Combo 1 and I have fast glass from 24-200 mm.
Disadvantage: My longest focal length is 500 mm, which will definitely limit photography of smaller animals (e.g. birds). Also not very fast at 500 mm (f7.1).

I currently own two R3 cameras and would like to use both on the trip and am open to renting a smaller camera (R6/R5/R7) if it makes sense and carry it as an addition or as a substitute for one of the R3s.

If anyone on this forum has been to Southern Africa (Botswana, Zambia, Zimbabwe) I would like to hear back from you on which focal lengths were the most useful. Any guidance is greatly appreciated.

I have watched numerous videos on YouTube and honestly it seems that they recommend every lens from 16 mm to 800 mm so. bit of guidance is appreciated.

I am most interested in larger mammals (hippos, giraffes, elephants, etc.), but birds would be nice to photograph as well.

All equipment needs to fit in a GuraGear 30L backpack and ScotteVest QUEST vest with 42 pockets. I think the vest will be good for cables, extra batteries and memory cards.


Thank you,

John

The Canon EOS R6 Mark II has “electronic focus breathing” correction, and it appears that at least some lenses need to be updated to take full advantage of this new feature.

The eternally rumoured Canon RF 35mm f/1.2L USM (or f/1.4) has been rumoured for what seems forever. We’ve seen this before with certain lenses, most notably the EF 24-70mm f/2.8L II and EF 100-400mm f/4.5-5.6L IS USM II. They existed and took forever to actually get announced and hit the market. We have been told

Hello! I hope that you can help me. I just got an R7 after shooting with a 7dmii with which I took tack sharp pictures. This is my first mirrorless, and I have worked with many different settings in the AF and Camera Menus. I have also reset the camera twice. Here are my issues:
1. All my pictures are in poor focus.
2. All my pictures are very noisy.

I have the following lenses, and the issue is with all of them.
1. Mount Adapter EF-EOS R Canon
2. Canon 24-105 f4
3. Canon 70-200 f2.8
4. Sigma 100-400 f5

I have taken hundreds of shots of ducks and flowers so that I would have stationary subjects and some subjects with slow movement.

I shoot in CRAW. Evaluative Meter. sRGB. HDrive. Electronic and Elec 1st-curtain. This happens with Servo and One Shot. AF
Area- I have tried all. I have turned off tracking and eye detection. When in Servo, I sue 2,4 or Auto.

I have read everything that I could find. Watched a milion YouTube videos, and I am unhappily stumped. I am willing to try anything, so if you have the expertise to help me troubleshoot this, I would be so grateful.

Is there any chance of putting the latest threads/posts on the front page again.
That's where I used to always land and see what was being talked about each day...

I currently have a Canon R3 and a bunch of RF lenses. I am very happy with this setup, and it really works for me. I shoot everything, and my lenses cover all my needs.

However, I really want a compact camera that I can always take with me. I was thinking the Sony A7C + Tamron 20-40mm f/2.8 would fit this. It is a very compact body, and the lens is as well.

I have no desire to replace/replicate my Canon kit with Sony, so I am thinking of this camera/lens combo as a one and done. If I think the situation might require multiple lenes I will just bring my R3. I love the R3. I find it a joy to use. However, it will not fit in a small camera bag even when I have my smallest lens (RF24-105f/4L) attached.

I know the A7C gets flack for the sometimes-uncomfortable ergonomics and viewfinder, but I am hoping this isn't an issue in my case when I am looking for extreme portability. I've mused about getting an A7IV instead, and while this is a much better camera, it is significantly larger, and if I was going that route, why not just get an R6 Mark ii than can use all my existing lenses. I'm not sure if I would like the R6 route, because I just sold an R5 (just a little bigger) and found the R5+25-105L combo to be a bit too big as a carry always combo. I really hate the RF small lens options due to their lack of weather sealing and noisy/slow STM motors. This is why the Tamron 20-40 is such a winner (enter Sony).

So here I am with the A7C. Does this seem like the way to go? Would I be happier with the 20-40 and an A74 instead? Will I appreciate its ergonomics and extra features over the A7C or will the added size make me leave it home more?

I appreciate any thoughts on this. This is about as first world a problem as they come!

I am a press photographer with over 20 years experience. About a year ago I switched from Nikon F-Mount professional, full frame DSLRs to the Canon RF R3 (mirrorless, full frame).
Just like other press photographers, I need a reliable, rugged, weather-sealed, L-Series lens with a wide zoom range (28-300mm, 24-240mm or?) and a manual focus switch for my photojournalism. Will Canon EVER make such a lens?
Currently I use the Canon consumer-grade 24-240mm NON-L-Series lens (NOT weather-sealed, not heavy duty and NO MANUAL FOCUS SWITCH).with my Canon R-3 bodies. This lens is a compromise. I will not buy an obsolete, expensive EF 28-300mm lens that was designed way, way back in 2004, plus an EF-RF adapter.

In the stadium where I shoot, there are only 2 photo pits (for pro men's games). One behind each goal line. So if you are shooting into the goal, it's from the opposite side of the field. Here is a shot with a Canon R3 and 200-400 lens, shot at 560mm with the internal 1.4X converter.

Am I the only one who starts to hate the new rear lenscap design?
I fiddle arround with it in daylight but I get desperate in low light situations,
meanwhile I just throw the lenses without a cap in the bag if under pressure.

Almost ironic fact: The R rear lenscaps fit perfectly easy on the EF lenses.

Any whispers about the r5c mark 2?
Will there be such a camera?

For 4K filming it seems the R5 mk II
Answers all the problems however the codec still requires a new processor or motherboard.

R5c was great except for its chunky body and shamefully awful battery life.
