Claimed Breakthrough Solution to Spherical Aberration in Lens Design

But doesn't that mean that one needs to reshape the lens surfaces in order to refocus the lens? Hardly feasible for general photography.

Also, the illustrations in the article suggest that the formula might not be suitable for off-axis objects.
Sorry for the late reply, I have the same impression like you. But I can imagine that intelligent optical elements made of flexible materials (like the lenses in our eyes) may utilize such a formula even for bigger lenses. On the other side, I am pretty sure that algorithms that control the shape of such a lens will most probably based on numerical mathematics, not such an attempt to tackle that problem analytically.

Another approach is to correct all types aberrations during post-processing, as it is already done with chromatic aberrations since many years. That's the most probable approach IMO, because it allows for simpler and cheaper lens designs.

Firmware: Canon EOS 80D v1.0.3

While all very witty, this is a real potential problem that is good to have fixed for some people. Canon's Hong Kong local site has a longer explanation: https://hk.canon/en/support/security-advisory-ptp-communication-and-firmware-functions/notice
Notice that if one has an 80D connected live to a smartphone / tablet / laptop and trying to beam out pictures of protests, etc, then state security has the resources to pull off this kind of hack and see what one is recording. Same for similar places around the globe. So yeah, good patch.
Still an utter fringe nano scale problem. Rather had a small functionality update upgrade.

A new EOS Rebel is coming this month, possibly an EOS Rebel T8i or entry level EOS M camera[CR1]

Nobody disputes that 1080P televisions were an excellent entry point into watching TV 10 years ago. But today, in 2019 they are simply totally antiquated tech and 4K/8K TVs are the only thing TV makers need to offer to get new buyers into their ecosystem and retain market leadership.

See how silly that sounds?
actually... you got me there for a second! until I read the last bit being: See how silly that sounds? phew.... :D

The RF mount “Holy Trinity” should be ready to ship before the end of July 2019 [CR2]

Maybe that’s normal in Canon’s world. But it’s messed up. Disney announces their new service is launching in November and it launches in November. Apple does the same. Most successful companies do. Why Canon has apparently strategically developed a reputation for announcing things consistently earlier than they come out suggests a very high level of incompetent leadership. The buyers of their products are, no doubt, their biggest fans. They should be embracing this fan base by providing updates on news flow and accurate estimates for releases. Whether it’s the hold trinity of 2.8 or the possibility of a 2.0, their fans want to know and plan for those releases. And it’s not like holding back that information gives their competition any advantage. Half of buying a brand is the brand, not the underlying product. They should do s better job building the reputation of their brand.
People insist on treating rumored release dates as Canon promises. So far as I know Canon has only said that the RF trinity will be out by the end of the year. I don't think Canon has announced release dates for any new F2.0 zooms. Sort of silly to hold Canon responsible for rumors that don't pan out or unfulfilled wishes.

Canon R experience

I didn’t want a new thread just for this question, so hope it’s okay to post it here:

Is there a way to edit the touch-menu in Live View?

The iso in the bottom right corner is getting touched and set to a specific iso value when I want auto-iso all the time. Accidentally touching when carrying the camera.
Edit on this:

I did find a way, I turned off the “buttons on screen” and instead of having the SET-button to “activate/deactivate touch-functions” I assigned it to Q-menu (since that disappeared from the buttons on screen)

Selling gear

That's a very good and fair question. To go to something that I think suits my individual needs better.. .

Thanks for the thoughtful response. I was a little surprised to learn you were dumping all your lenses, especially the 70-200, but obviously you've thought this through. I will say that the more I use the R the more I like it (although not so sure about the control bar thingy). Me, I'm not ready to dump the DSLR quite yet, but can see how future purchases might not be in the DSLR format -- depending on what Canon does with the "R1x" body. As for my EF lenses, I will hold on to them and defer R lens purchases until I see how things shake out.

Thanks.

The follow-up to the Canon EOS-1D X Mark II may come in 2019 [CR2]

Hi all, I am not so interested (yet) in the EOS R as I think Canon technology is not yet so mature. I am more interest in a replacement of the EOS 5D Mark IV possible.
I am wondering if anything think that by April 2020 anything concrete will appear in shops (I mean ready to buy, NOT just rumors or announcement for later release).
Thanks in advance.
Andrea
OK , so where are the clairvoyants in our group when we need them?! ;) I can recall one who makes great claims but they never materialize. :(

Still worth buying a T7i/77D this summer?

I have a 6D and a couple of older Canon crop cameras. I wanted to upgrade the T2i and the 77D makes for a small and sharp travel camera. I bought the 77D a month ago. The image quality is better than the older crop cameras, and the features are better than on the T2i. It makes me want to sell the 60D and T2i.
If you want the best low light performance, the 6D is hard to beat. If you want a smaller body with a tilt screen, top view screen and the features of the 77D, it is a deal right now. If you want a crop body, I would go for the 77D if you want a small body or the 80D if you want to spend a bit more and get a larger camera with more features. The 77D has a good feature set and works well, especially at the current pricing.

IDXMKII - Please tell me I'm waiting for WOW!

I have an 80D (and some other cameras).

This feature / functionality is only found in the M5 (and M50) - i.e. where the touchscreen can be used to move the AF point when eye is pressed to the EVF (and EVF is one). Once you get used to it, that works very well - quick and precise.

Paul

Eos R has this functionality as well.

EOS R AF with 1.2.0 firmware

I’ve not had extreme success with the R plus RF50 for tracking faster’ish action, so I tried the RF85 tracking my son on his scooter, kicking away down a small hill, and it was very, very accurate wide open. Out of 15 shots I had two that was slightly off his face and locked on his shirt, but the other were all on his face. After quite intense testing with RF85 I find it better for AF than the RF50. Neither can track fast back and forth movement, and will completely loose focus on those playground items where for example a horse sits on a huge spring on the ground one can rock back and forth on. I tested on those since I had a reference with the 1dx2 there. The 35 L II with 1dx2 was very good, but far from perfect. The 24-70 II was best with 200 f2 and 70-200 II close second.

But when it comes to accuracy for everything else the R blows the 1dx2 out of the water with fast lenses.

Stock Notice: Tamron 35-150mm F/2.8-4 Di VC OSD at Adorama

Pan the scene and stitch - problem solved - make full use of this digital era ;)

The Tamron 45/1.8 is a beautiful lens. I have the 85/1.8 too and that is also excellent but in a much more clinical way. However somehow I just don't feel the same about Tamron zooms. I've never had one but of course as this is the Internet it doesn't stop me from being highly opinionated about it :)

I’m lazy. I don’t like doing much in post :) but... since you recommended it, I’ll give it a try next time I’m out, and see how it works out.

Never had a Tamron prime, but have had 3 of the zooms and liked them all (but never loved). I am, however, really liking the newer 17-35 as a high quality and very light travel wide angle. Got more photos with it that I like than my canon 11-24, simply because it’s half the weight and size, so I’m much more likely to carry it with me.

One thing that was fixed in EOS R firmware 1.2.0 that I haven't seen mentioned anywhere

I reported the 'magnify to original size at AF point' issue to Canon as a bug.

Glad they listened to me :)

Apparently, it never worked before in live view. So given that the R is basically just a live view 5D4, it wasn't there at launch. I wonder if others complained too? I used the feature exclusively on my 5D3 and 5D4's so I am very glad they 'fixed' this. My workflow is restored.

Two more things left:

1 - Allow a RAW file to be written to the card AND wirelessly transferred
2 - Allow exposure preview while a flash/transmitter is in the hotshoe

Then I'd be completely satisfied...
Luckily a lot of us reported the magnifying issue (y)

Raw files transfer would be excellent since I have Lr on my phone and I’m not sending away no OOC jpeg:ROFLMAO:

Thinking about going mirrorless and looking for advice

If you are not doing sport , birding or chasing the kids, mirrorless will be good for you. Whether you want a R or M is is another personal choice. If you are concern about weight, the M is a better choice, due to the size of the weight of the R lenses ( they are better than the M lenses). I switched from 40D+ 20D to M+M2, and later M2+M50 . My major (95%) use for them is travelling. I have never look back. The strength of M is light weight, small size and reasonable priced lenses with good performance. you can have native lenses( mostly zoom lens) from 11 mm to 200 mm. that should be more than enough for most people as a travel camera. The 22 mm 2.0 EF-M is an excellent little lens.
