Have you used any lenses with molded elements in your high humidity environment?

I think the people clamouring for 50/1.4 are ACTUALLY asking for one of the two lenses we ALREADY have. Either they want something like the EF50/1.4, a double Gaussian design, cheap, compact, good not great IQ, and so basically what the RF50/1.8 is, once you factor in the lower need for raw F-stop these days. People are hung up on the 1.8 vs. 1.4 but I think that is a mistake (and one I made for 3-4 years before finding peace!). In other words, the RF50/1.8 **IS** the double-Gaussian RF50/1.4 you've been waiting for.

Canon's problem is that they really low-balled the 'economy' lenses; so while you're right that a light 50 f1.8 might be the right ballpark for a lot of folk; that particular 50 f1.8 might not be. It's definitely built down to a price, it's not weather sealed, and the close focus IQ is poor.

Canon is doing pretty well rounding out the RF lenses and bodies for the pro crowd, for the sports/wildlife crowd and for the low to mid enthusiast crowd.

I think they still have a wide-open hole in provisions for the light weight/street shooter/travel well heeled enthusiast crowd. The sort of folks who buy Leica Qs, Fuji x100vis, Nikon Zfs etc. A nice compact setup with high quality primes, high build quality, weather sealed. The sort of bracket Sony is hitting quite regularly now, that Sigma hits with it's 'i' series glass (all beautifully made from metal, all weather sealed). Really it's a shame the 28 f2.8 isn't better made; because it's an interesting proposition for someone building a light street/travel kit, but it's not going to tempt people away from the Q/Zf etc.

As title, wonders if the sensor is still draining battery or the shutter is closed sensor power down?

Click to expand...

The shutter stays open in ECO mode when the screen and EVF time out. Not sure that means the sensor is in a power-saving standby mode too or still "draining the battery." If the sensor is still at full, active power, then "Eco Mode" isn't so Eco.

What drains my battery the very fastest is having the EVF and screen set to automatically switch back and forth whenever the EVF proximity sensor is triggered, as I'm almost always brushing my elbow, strap, hand or shirt material near it when walking. I've set my camera to use the video recording button to manually switch from back-screen to EVF as I lift the camera to my eye. Can easily double, even triple my battery time, as the camera is also set to ECO mode, and when done taking photos, I reflexively switch from EVF back to screen, which then times out quickly.

In the studio, when I don't use a strap, I usually put the camera on a cart when not actually photographing, so for that situation I do use the automatic EVF to back-screen function. During a session, ECO mode is off.

It's easy to change settings so that the video recording button goes back to doing what it's intended for.

This morning I picked up an extra B+W clear filter open box from B&H for $170 instead of of $250. Nice to have a back up and to save $80. The first time I have ever purchased anything used from B&H.

Wonderful photos with a wonderful presentation!
The last is very impressive for all the right reasons!

Looks like the Exposure Comp button in Manual didn't get fixed... seems fine otherwise.

Nice series, @docsmith ! Love the architecture in front of those moody skies!

frankly I am still using my good old 5D3, but since my first DSLR (40D), I always have the BG glued on to my 5D3 for a decade, the ability to hand held it in all direction and always have the joystick at hand is a big plus, especially you go shoot for events or wedding where there are scenes you do vertical composition most of the time, the extra battery is also very good for even the DSLR, it's really nice for a 10 days trip overseas to only drop 2 batteries in the grip and not even need to bring the charger, it always have the juice to sustain the 1500 photos. for RF cameras I am sure the battery will drain a lot quicker, but then, having a longer sustain period is really nice

Is there a comprehensive chart somewhere that shows all the RF lenses (to date) IS ratings with and without IBIS on the R5 and R7?

Squid and green beans......looks very tasty!

PC Mag, one of the better sites, and has published a review today. It complains that the AF is not very consistent, especially in dim light. I find for BIF the AF is not tip top but good for static birds. His MTF resolutions are quite different from those reported by Digital Camera World, which had the lens sharpest at 400mm and very weak at 800mm. "Using the standard chart, the lens scores right at the cusp of the excellent range for the 45MP EOS R5 sensor at 200mm f/6.3-11 (3,700-4,100 lines). With the smaller chart, the results are lower (2,400-2,600 lines), but in line with other long lenses I've tested with the same equipment. Lab results are a bit better at 400mm and f/7.1-16 (2,400-2,700 lines), the best at 600mm f/8-16 (3,600-3,000 lines), and slightly lower again at 800mm f/9-11 (2,900-2,500 lines). It's typical for a lens to get sharper as you stop down, though diffraction and vibrations during testing likely caused the drop-off at longer focal lengths. Even so, we consider these results excellent overall." These are in line with what I find from comparing fine details from birds and charts, and the two testers have lenses with wide copy variation.

Digital Camera World, on the other hand, finds the AF exceptional!

The tester prefers the RF 100-500mm because of better AF. I'm finding that 90% of my shots are at 800mm so I am tending to use it more than the 100-500mm, and the two have very similar sharpness at 500mm, with the 200-800mm probably slightly better.

I could go for a PowerShot Super-Zoom, akin to the old ones. I had one that used AA batteries and there's certainly demand for that from the "Go places and take photos!" crowd that wants something more versatile than a smartphone and less clunky than a DSLR or mirrorless equivalent.

Better for your shape. Otherwise you'll get hungry and start watering

I posted earlier that the copy of the 200-800mm that I was eventually able to buy was sharper than the copy I had first tested. Yesterday, I had the opportunity of taking more shots of the target rigging under very similar light to previously, but with different sky/cloud colour. The difference in sharpness and contrast at both 800mm and 500mm is noticeable. You simply can't rely on sites that just look at a single copy of a lens - the only one that counts for you is the one you have, and you have to be able to test lenses before final buying.

to answer my question... https://help.mevo.com/hc/en-us/articles/23527798694036-Mevo-Core-s-Supported-Lenses has the following table:

Although we don't sell these lenses directly and have no official partnership with these brands, they have been tested for optimal performance with Mevo Core:




Key:
- Powered Zoom: Lens zoom controlled via Mevo App gestures/manual sliders.
- Zoom: Manual zoom adjustment directly on the lens.
- Prime: Fixed focal length; no zoom capability.
- FL: Focal Length - distance between the lens and the image sensor when focused.
- Ap.: Aperture - the lens opening that controls the amount of light reaching the sensor.

Each flash manufacturer has their own ID code so what ever transmitter you are using it has to be paired with a receiver of it's own kind .
I use the Godox 600s 200s and V1s but in the studio i have a mix of Godox and Alienbees, for the setup I have and old Adarama transmitters and receivers can't remember the name but they have a hotshoe so place the Godox transmitter at the top and trigger both lights at the same time. If you are in a studio you can also use the optical sensor to trigger your other brand providing both lights can see each other. However it's best to stay inside the same ecosystem, if you have Godox they have a wide range of lighting for all occasions along with Profoto and Westcott.
If you use studio strobes like Godox just forget about the Canon flashes and invest in the Godox ecosystem.
Good luck.

Thanks!
I wish I had gone Godox from day one.
I use several Canon 600 ver 2 RT and 1 430 RT and Yonguo 600 flashes.
They work together but they all glitch.

Today I had 4 flashes going and they were flawless, until I shut them down.
Booting them back up was a nightmare.
I sort of laughed at Profoto prices when they first launched, but I at the point Profoto seems CHEAP if the crap works every time!
( I really do not mean that, it would cost me 9k to switch to profoto)

I have found that both the Canon and the Yonguo are a little more reliable with the Canon trigger if I set them to never sleep.
But the units can be very warm at the end of a shoot.

Tomorrow I have an academic presentation in a room with flat black ceilings but white walls. I may set up 4 Yonguo as slaves up high and light the entire room with just a touch of flash at 45 degrees chriscrossing the room to break the harsh crap straight down industrial lights in the place.

Canon is so 2030s high tech as a flash that I carry a bunch of these 1980s peanut slaves as backup.

I bought a Yonguo 560 for a light behind the seamless but the optical slave did not pick up, so it was moved to a rim light and worked just fine in that role.

Recessed? My son is ALWAYS in a better mood after recess.

By the way, your web link under your name is pure poison. Spam, malware...Please fix that!!!

That is an approximation I picked up from ... somewhere.

that is with rr being short for "resolution ratio", which means objective resolution on sensor side divided by the pixel spacing. Variable "hp" is number of pixels horizontally. What is the best exponent is somewhat open as is whether it needs some correction constant instead of current "1" as divisor. That would handle Bayer effect and angled lines.

You must have got a good one, since there seem to be copy variations. Mine was just OK, but definitely not as good as the EF 24-70 F4.[…]

Click to expand...

The important bit for me that it needed to be better than my EF24-105L, the mark I version. The RF cleared that low bar easily

My copy of the RF is not as sharp as the one I rented years ago, but only slightly. Sharp enough for my uses, if I want better sharpness I’ll use a (non-L) prime.

@docsmith, your snapshots from Portugal are truly inspiring! The old fortress in Lisbon with its peacocks sounds enchanting, and the opportunity to create personal tiles is a unique touch. Your experiences at Sintra’s historical sites and the Algarve’s natural wonders like the Benagil sea cave add to the allure of these destinations. I appreciate the recommendations and will definitely consider adding them to my itinerary. Also, a big thanks to @Click for the kind words. As I’m quite new to photography, any advice on choosing the angle for my photos? I’ve seen the profile of “José S.” who is both a professional photographer and a local guide here https://gowithguide.com/portugal/guides. Do you think it is worth it to get the services of a local guide, especially one who is also a professional photographer, to help me with my shots?

My European electronics engineering sources have recently told me about Canon Singapore sources showing off an internal document about the current iPhone sensor of 7.01 x 5.79 mm being replaced with a Canon or On Semiconductor manufactured RGB imager and lens-assembly. A set of 64 Megapixel one inch sensors is now being tested at Apple which are 13.2mm by 8.8mm (i.e. RGB Bayer-Patterned 1.3 microns per photosite) very-high-light-sensitivity imagers that are rumoured to rival even Sony Starvis image sensors in terms of low-light sensitivity. The KEY ISSUE is that Apple has been looking AWAY from Sony as its primary image sensor supplier via recent exploratory talks with On Semiconductor AND Canon being leaked to external 3rd parties!

My European Engineering Sources have told me that Apple and Sony have been having a recent technology and price disagreement about high-light-sensitivity Sony RGB image sensors not being made available at the price points Apple is looking for. Exploratory talks with BOTH On Semiconductor AND Canon have indicated a willingness to supply large and very light-sensitive RGB image sensors for super-smartphones at a minimum of 64 Megapixels (i.e. 9216 by 6912 pixels) in resolution.

A research and development contract was seen by an external 3rd party which indicated that Canon and On Semiconductor are both willing to supply such high light-sensitivity imagers to Apple at the price points needed. The current in-house rumor has Canon having the current technology/production lead over On Semiconductor due to an obvious and documented difference in the reduction of luminance and chroma noise between the Canon-supplied and On-supplied 64 megapixel one-inch-sized test image sensors during low-light conditions. Basically, it was found the Canon sensors looked much nicer on RGB output at pre-and-post sunset and sunrise light levels and during night-time street lighting photography scenarios in both still photo and video recording sessions. The new sensor offerings will be for an upcoming series of higher-end iPhone models. The exploratory talks with both image sensor suppliers were rumoured to have taken place in May 2023 with test sensors from both companies being shipped to Apple by December 2023.

I suspect Apple is trying to show Sony that it isn't kidding around and is VERY WILLING to change suppliers if it doesn't play ball with supplying low-light sensors at a good price point to Apple. Apple is large enough that even Sony is not immune to being put on notice for providing Apple a better price point or more technology-leading sub-systems!

I should also note that an American-based LIDAR/IR emitter supplier was ALSO INCLUDED in this exploratory set of talks which indicates Apple is likely going ahead with the long-rumoured high-resolution 3D-XYZ scanner that will be included in future iPad and iPhone systems used to support live 3D-XYZ object and 3D-Environment scanning during still photo and video recording sessions to be used as datasets for the Apple Vision Pro AR/VR glasses systems now available and for those future AR/VR glasses versions in current development by Apple.

This LIDAR/IR scanner is a ALSO part and parcel of the long-held-rumour that Apple is exploring the world of designing and building super-fast metal powder deposition 3D printers and super-fast plastic resin 3D printers as an entirely new product category for Apple where it has the fastest multi-head 3D printers along with the most durable and tough metal and plastic resin 3D printing "inks" around! You need really good high-resolution RGB imaging and 3D scanning for that and this rumour starts to look more and more like a very coherent internal product plan that is very forward thinking for Apple! I actually can't wait to see an Apple plastic and metal 3D printer --- After personally sampling what the Apple Vision Pro can do for AR/VR, I can DEFINITELY SEE the potential of ultra-high-quality Canon or On RGB image sensors within Apple iPhones/iPads being used for 3D-Scanning and super-fast 3D-printing!

You Heard it Here First!
