I've been using Pentax cameras since 1977. Due to my arthritis I am probably switching to Fuji MILCs. But still keep the Pentaxs and use many of the lenses on the Fuji. Also I think Canon menus would seem less foreign to me. I hear Sony is odd, as is Nikon in that area. Not interested in anything smaller than APS-C format. I used to use a 8x10" View Camera at one time. The IQ of my two film 4x5" cameras is still astronomical!

My two favorite cameras thus far of many, have been my

K-5 (digital)
K2 DMD (film)

I also miss my (stolen in 1987) K1000SE as it hand a split image focusing screen. A great thing not found on digital cameras it seems.

Well, you did buy a mirrorless Camera with two lenses for $425. What else did you expect.

You will be delighted! I shoot Sony, Nikon (D850, Z7) and Leica. I give the edge to Sony.

It's not going to be just the size or number or hard drives you have, it's also going to be how much RAM and how fast your motherboard and processor are. I have a friend that bought a Nikon D800 when they first came out and his computer couldn't handle the huge files without the hourglass spinning and spinning. In other words, it took forever to process those images and your Sony is going to have even bigger images.

I'm not bagging on your choice of cameras, there are a lot of people going to Sony cameras. They seem like fine pieces of gear. I'm a Canon guy and have a lot invested in them so I don't see myself moving to a different brand any time soon. But if and when Canon comes out with the mirrorless camera of my dreams, I may add one of those to my collection. So far, they haven't done that.

To jump on UHH and ask us if you made the right decision is kind of moot. You've done it, and now you should give it a chance and then report back and tell us how you like it instead of dreading making the wrong decision. Roll with it and I hope you are happy.

I think you'll be happy with the Sony camera... 61MP, after all, is nearly triple the resolution of your antique (in DSLR terms) 1Ds III.

I never really understood what Canon did with that 2007 model. How was it that the 5D Mark II, released less than a year later, had higher selectable and usable ISO while using the same sensor? At the time it was surprising that they even used the same sensor. I suppose the IQ difference is that the 5DII got a Digic 4 processor, while the 1DsIII used dual Digic III. But it always struck me as odd that the "pro" camera's ISO range was 100-1600, expandable to 3200... while the "consumer" camera's was 100-6400, expandable to 12800.

I'm not sure a high ISO range has much to do with dynamic range, though. In fact, dynamic range decreases dramatically with all cameras, as ISO is increased. This website charts the relationship between ISO and DR, for almost every camera model (I've highlighted the Sony and several Canon for comparison... you can change them easily by clicking the model listings on the right). What's important here is how DR is effected as ISO increases. The Alpha 7R IV appears to have less than half the DR at ISO 12800, than it does at ISO 100. Of course, landscape photogs often use tripods that allow them to make longer exposures that keep their ISOs low.

Resolution is what it's all about, with landscape photography like you enjoy doing. And the new Sony currently has the most of any full frame camera (only medium format digital offer more, but the cost, size and weight increase significantly with MF). Rumor has it that Canon will be releasing an EOS-R model with even more megapixels (83MP?) in the not too distant future, but for now the Sony is top dog.

These ultra high resolution cameras are very "demanding" of lenses. They need "good glass" and are unforgiving of any flaws a lens might have. There are all kinds of reviews online, both formal and informal. I find the feedback from the guys at Lensrentals among some of the most useful, since they handle and regularly test dozens of copies of any particular lens model, in the course of their business. Regarding the 70-200mm, you might want to check out: https://www.lensrentals.com/blog/2019/07/just-the-mtf-charts-70-200mm-f2-8-zooms/

I don't see any Lensrental discussions of the other lenses you mention (but you might search their blog more than I did).

I also find Bryan Carnathan's The-Digital-Picture website helpful with detailed reviews and lens comparisons. You can use the Image Quality tool there to compare test shots done with almost any two lenses side-by-side, and see for yourself how they might be expected to perform. There you can see how some of the Sony lenses compare against lenses you used with your Canon DSLR. Of course, most likely Bryan only has opportunity to test a single lens, so any copy variation isn't taken into account, the way it is at Lensrentals. But, hey, it's something... Better than buying things "in the dark", more info than many reviewers provide and let's us see for ourselves how things compare...

No review and testing of the new a7R IV yet. https://www.the-digital-picture.com/Reviews/Sony-a7R-IV.aspx

Personally, if I go mirrorless with my next full frame camera, I'll be looking at f/4 lenses. Especially for landscape photography, where I'd nearly always be stopping my lens down to a middle or small aperture anyway. f/4 zooms are smaller and lighter than f/2.8 zooms (which look pretty hefty mounted on mirrorless cameras!) Not to mention, f/4 lenses are less expensive. In most cases they are at least as good and sometimes f/4 lenses are sharper in the corners of images.

If it is really an improvement over the a7Riii, you are in for a treat. The contest between me as a photographer and the iii as a camera just doesn't exist. Sony wins hands down.

Welcome to the Sony world. I made the change from Canon in 2013 with the A7R then an A7S. I've also had an A7 II and an A7R II. I didn't like the A7 II's low light performance and the 42 MP of the A7R II was nice for resolution but the file size was too much. I still have the A7S, full spectrum converted, and an A7 III; both have superb low light performance.

You'll grow to love Sony full frame cameras! I have.

P.S.: Don't forget your Canon lenses; some of the best available. I use mine with Sigma's MC-11 adapter.

When I switched from Canon back to Pentax, I found the controls to feel familiar. When I did my spreadsheet five years ago, lack of an EVF was my only reason for not staying with Canon and getting an EOS-M. The Sony seemed a tad strange ..... and I don't remember anything about a Fuji. If I were making the same decision today, the EOS-M50 would be very high on my list.

You seem to have a habit of replying to posts and saying you know nothing about the subject and can't be of any help.

Why bother replying?

Since the first Canon DSLR (1D) came out in 2001, your title isn't quite right.

Obviously he had film cameras too.

I guess the title should use the term "(D)SLR".

I have a good friend who has recently made a switch from Canon to Sony and he said he just wishes he had done it sooner.
