I "think" I'm finally ready to try an A1ii. I have been watching too many videos/reviews of the sony's, canon's, and leica's, that I'm going mad. Here is what I want very simply, a smaller camera that has the autofocus speed of my R3, a nice clean EVF (eyes aren't what they used to be) higher mp's so i feel like I can crop (in camera and in post) without losing too much detail, and some smaller lenses where my kids don't roll their eyes every time I go to take their picture with my R3 and 28-70 f/2.

I test drove an A1ii for a little bit and was then serendipitously presented with an opportunity to get two R5ii bodies for less than the cost of a single A1ii. Do I ultimately think the Sony is the better cam all around? Yep. But it certainly doesn’t come close to being twice as good.

I’ve been a Sony/Canon/Fuji shooter for a long time and I’m a gear nut, so I maintain multiple rigs from each company. Based on what you’ve stated, I feel like you might benefit from getting an R5ii and an A7Cii for when you really need compact. The A7Cii may not have a stacked sensor, but it is by far the most compact and capable FF body on the market. It also has the added coprocessor for AF functions which makes it quite proficient in the AF department. I routinely have both in the bag with me.

Hi All,

I have made experiences with both, the A1II and the Canon R5II. I have been driving myself mad (and my GAS wasn't helping), because I wanted a new camera system for Wildlife shooting on my next Safari. I've started with a Leica SL2 and a Sigma 100-400, which is easy enough to improve on, but this system had already something pretty unique - an amazing viewfinder, which is beside all technicalities in my opinion very enjoyable and almost lifelike.

After a quick test of an R5II and an A1 Mark I I decided to order the A1II, assuming that with the AF improvements it should be at least on par with the R5II. Main reason was spec sheet hunting - better viewfinder, higher resolution, faster sensor, super flippy dippy screen, best lens system on the market ... - you name it. I waited ages, committed also several lenses (200-600, 35 GM, 24-70 GMII). First things first - it is an amazing camera. I would not hesitate to call it the most complete camera on the market. That said, I failed to enjoy it. I used it for street, tested it with wildlife, but it was never fun. Three things, which looked great on the spec sheet, but were never great in practice:

- Viewfinder: although the best viewfinder on the spec sheet, it always looks like a screen, not like reality. It is overly sharp, resolution drops, ... . It is on the spec sheet blowing all others out of the water, but I recon that Leicas viewfinder just looks better to the eye, Nikons viewfinder looks supposedly better from what I heard, and honestly I quite like the viewfinder in the R5II better in real use cases.
- Autofocus: There is so much talking about the AF system, that it is almost impossible to get to what it means to us individually. First things first: the AF system of Sony is second to none. The tracking is best in class, human subject recognition and tracking is certainly good with almost every brand, and the options you can configure are mind-blowing. You will be able to do everything with this system that you need to it do. What was in my opinion by far not there where the Canon is, is the subject recognition.
- Weight: I found the combination of the A1II with the 200-600 extremely clunky and heavy. Yes, again it looked great to have a high performing internal zoom, and yes, it is only 2.7kg according to the specs, but in reality, when I've put it on a scale, it was 3152g (measured!). The reason is, that they just mention the bare lens, but when you add the tripod collar, the lens hood, the lens cap, etc., then you are adding significant weight. The canon with the 100-500 is significantly lighter (~2700g, haven't measured it yet myself, but I love it). And that is one of the reasons why the OM Systems OM1 Mark II with the 150-400 was much more fun to use, see below (measured weight 2654g).

I am cutting to the case. I had committed a serious amount of money, and I had the "best" camera on the market with the "best" possible glas (please spare me the discussion on WL primes - too expensive and I think zooms are better for safari unless to need to make a living out of it).

Then I tried to photograph a bird in a cage in front of me, and the camera didn't acquire the bird, whatever I did (unless I used spot AF, which is the way to go with Sony in "difficult" cases). I was so annoyed with it that I decided to try OM Systems OM1 II with the high end glass. And, what happened? I liked the viewfinder, I liked the AF (even though it is supposedly and most likely objectively "worse"), I liked the handling. I didn't like that it would have cost me almost the same amount of money that I had spent on the Sony system. I knew that the Canon has the objectively better subject recognition, and after some scrutiny I was able to get to the bottom of any marketing bla - when I actually take the right lenses (RF100-500, RF28-70 f2.8), I am able to get one of the lightest, and in the same time best performing systems on the market, despite all influencer BS. I was able to get a good deal, saving some money, and jumped.

And now what? I have a tremendous amount of fun in every shooting situation so far - street, wildlife, documentary. For anything else I am anyhow using Leica digital and analog.

What I want to say is the following: the technical nerd in me was initially doing an excessive amount of research and engineering to get the best possible outcome. It reminded me of comparing the Nokia N95 to the first iPhone - the Nokia was winning in every objective category. I got the iPhone and never looked back. Here I decided to go for the Sony, and that was for me a mistake, because I didn't go for the handling, but for the spec sheet.

Or in other words: My recommendation is, choose the system what feels better and forget the spec sheet optimisation and what you can find in all the videos on Youtube. I would say that I finished watching all videos about the top cameras, and it wasn't really help - it is more like watching voluntarily 600h commercials than anything else. Test it. And from your background I would find it hard to believe that Sony would be doing the job better for you than the Canon - and you are even already heavily invested in RF mount. You can get two VCM lenses and an R5II, or any other sexy combination for the same money than the overpriced (yes, now I said it!) A1II.

The A1II for roughly 10-20% more than the Canon R5II would be arguable, but not for 100% more.

I am very happy Canon user now.

I hope that makes all sense and helps a bit.

Cheers,
Toertel

My advice from someone who has bought and sold more gear than I care to admit: If you already have a Canon kit and there's not much bothering you about it other than size, I personally would just look at a smaller camera within that system and one or two small lenses to supplement your larger ones.

I personally have never liked Sony ergonomics, but I've been shooting Nikon and Canon for my whole career and so I'm most comfortable there, this is my own bias.

But the R5II is an incredible camera, and without a grip it's quite compact. I have the 28-70/2 beast, but I also have the 28/2.8 pancake and it's brilliant. I love it. I also have the 35/1.4VCM which is a bit bigger but still a lot smaller than the beast.

There are some real benefits IMO in sticking with one system and having options within that system to suit your different use scenarios.

I use Nikon Z8's at my day job, they're heavy and some of the lenses are heavy as well. So not sure that would solve your problem, although they're workhorse cameras. I don't like the AF as much as Canon for documentary/event coverage, but that doesn't sound like what you're doing.

Switching systems is expensive, I'd suggest spending that cash on travel, a workshop, or something else that actually involves going out and making photographs. But if money isn't an issue, then just go for it and sell it later if you don't like it!

I have found that "intangibles" are almost always more important than paper specs (unless there are some egregious differences)... Good for you to have recognized this in the end.

So many forum wars are fought over hair-splitting specifications--it is honestly exhausting.

It's also worth recognizing that personal preferences play a big role in how we respond to gear. Some people love the more tactile analog control scheme of, say, Fujifilm, while others won't. Neither preference is right or wrong.

I decided to order a RF 45 1.2 and see what that produces for a walk around lens on my R3. After some serious thought, I don't think I'd get along too well with an R5ii body as it's been forever since I've not had a canon 1 series body and would miss the integration of the battery and am so familiar with the placement of everything. If the 45 1.2 works out, great! If not, I may try a small sony or Q3 43. Heck, I may still try one anyway.

I've appreciated all that have commented. I love being able to post a question and get such honest and respectable replies. Happy shooting everyone! Getting on springtime! Can't wait!
