p.1 #1 · p.1 #1 · A7CR or A6700

Considering switching systems from Fuji to Sony and wondering if anyone has done a direct comparison of these two on a couple of areas.

I have three main areas I need a camera system to be able to do well in
- Travel, so size and compactness of body + lenses is super important
- Aviation, focused on good long lenses with C-AF, continuous shooting and buffer, and resolution also really helps
- General kid/pet photography

I was planning on going with an A6700 to minimize size of kit and lenses, but with the A7CR having a 26 MP crop mode in a similar sized body, I'm wondering if it would just be better to just get the FF camera and have the option of being able to use either the full sensor or just in crop mode. Cost is a factor, but the cost difference won't deter me if it's just a better overall option

Questions...
- How does the A7CR do in terms of AF, compared to the A6700?
- If recording in crop mode, does it auto crop the entire RAW image? If anyone is shooting APS-C and cropping in post, is it distracting or challenging to try to imagine the crop in your head while you look at the FF image?
- Am I just way overthinking this and should just get an A6700?

There isn't a difference in AF speed or stickiness. They're working with the same systems there. IBIS is the big improvement between the two and it's necessary for the FF. It's a lot easier to stabilize the smaller sensor. The 6700's max FR is 11fps where the cr is 8, but, with both of them, by the time you're shooting the max continuous, you'll pretty much be framing on faith. The EVFs and LCDs have a hard time keeping up. You also get a full mechanical shutter on the 6700 and EFCS only on the cr, if that matters to you.

Yes, video and stills, if you're in crop mode, that's all you're recording. When I had the rV, I never bothered using crop mode and just cropped in post.

No, I don't think you're overthinking it. You should get the right camera for what you need. The cr's a good camera, but if the 6700 does everything you need, then it will save you a small pile of cash.

thanks for the insight - I think I'd occasionally want to use full frame primes to their full potential but mostly just shoot crop, so if the A7CR can do both... seems like it might be a nice compromise.

I'm mostly shooting aviation when I'm at full burst rate... so the AF has been the limiting factor over the burst rate up to about 8 FPS (and this is the real reason why I'm considering changing is that I've found Fuji's C-AF to just not be good enough for what I need)

Mechanical shutter is kinda like cost... it matters, but it won't be the deciding factor

I currently own both and to me they are both excellent but will cost you more for the full frame kit by about twice as much when considering lenses of equal capability and quality. I.e. the Sony E 16-55/2.8 G is excellent but it’s Sony full frame equivalent is the FE 24-70/2.8 GM II at about $1000 more if both bought new. There are lenses like the Sigma 24-70/2.8 DG DN II Art that will cost you about the same but the for APS-C Sigma has the 18-50/2.8 DC DN which is about 50-60% less as well.

Resolution is key. Do you need 61 Mpixels vs 26 Mpixels or should consider saving some money on full frame and going with the 33 Mpixel A7CII? The lenses you would use on the A7CII are really the exact same ones you would use on the A7CR so if you want full frame you could save about $800 if you go down that path.

p.1 #5 · p.1 #5 · A7CR or A6700

I'm not super knowledgable about comparing Sony bodies, but my general thoughts on the A7C series is that they're not terribly smaller than the A7 cameras. The stats say they are lighter, and dimensionally smaller, but functionally, every time I hold one and compare it to a regular A7 body, the delta is really not noticeable. It really just amounts to removing that viewfinder module from the middle to the corner... and really that's about it.

Meanwhile, the A6 series bodies are quite a bit smaller and more portable than either the A7C or the A7's.

Not to make your analysis even more confusing...

I'm not terribly into specs and performance, except maybe how quickly a camera's AF system tracks and such.
I've owned numerous Sony bodies in the past, and they all left me feeling pretty blah, though they were all good cameras.
The A7CR is the first Sony camera I'm somewhat excited to own, even though it has the usual Sony menu system and could probably use one more custom function button. It's a great camera to handle and very easy to use.
AF and image quality are superb, and the package is very compact. You'd never think that it's housing a 61MP sensor with all the bells and whistles, but it is and it does it all very quietly and modestly.
I chose a large sensor for the ability to crop first, and print large occasionally, second.

I have an A7Riv and A6700. The smaller cameras are usefully smaller than the A7/A9s, especially as they've crept up in size. Tough call. I believe the video features and mechanical shutter can be important for some users. OTOH, I found the high res can be useful if in a travel/light mode with that crop room, perhaps if choosing to go with a single lens, like the 20-70/4. You also could go with the aps-c lenses and not lose anything to the A6700 on the lens/low light side, etc.. I would probably go for the A7CR if forced to choose

I recommend to clear your lens, focal length needs. I definetly opt for A7CR long term, but it's always depnds on how much money do you intend to invest in a system, what kind of glass do you need. 60MP is a lot of detail, with huge cropping ability (not as much what you think however), but this sensor torturing lenses, you need the highest resolution glasses, but lot of them are not as small, and you'd lose the compactness of your kit.
Some small primes for A7CR: Sony 20 1.8G, Tamron 24 f2.8, Sony 35 1.8, Samyang 35 1.8, Sony 40 f2.5G, Sony 55 1.8, Sigma 24-35-50-65 f2, Voigtlander MF APO lenses (35, 50 f2).
Small zoom lenses: 16-35PZ, 20-70f4, 16-25G, 24-50G.
Look into the APS-C and FF lens selection, the camera body is less than half part of your system.

Hm. Maybe you're right.

For the record, I have an A7R4, 650grams, and an A6500, 450g. I remember going to a store when the A7C2 came out, eager to consider getting it, but when I put it side by side with the A7R4, I was really thinking, 'meh, not going to spend $2200 to shave off a few mm's and grams.'

But it looks like the delta between the A7C series and the A6700 is not that big of a deal.

Though, really, the size difference is in the lenses more than the body.

You should see the difference between my A7R4 and my Nikon Z8, lol.

There is a such a thing as too small as well. I had the a7Cii, but I found it too small for my hands and I missed a good EVF + customs buttons. But if you like walking around with a good prime lens, e.g. 40/2.5 and a a7Cx (take your pick between Cii and CR) and you like to shoot via the back LCD, then I think that is the way to go.

thanks for the insight! For me, the resolution of the A7CR would be the real reason to get it over the A6700, so the A7CII probably wouldn't meet my needs. My use case would basically be with either the Sigma 500 5.6 or Sony 200-600 to have tons of crop room when doing aviation.

Really, besides that, I would probably buy mostly crop lenses anyway to stay light. Generally, it would be used as a "crop" camera like 80+% of the time with the option of being to able to use the FF sensor when I want it. I just wouldn't want to end up keeping a crop kit with a $1200 body AND then decide I wanted a high res body too.

At this point, I'm honestly leaning towards buying the A6700 and waiting to see if there's deal on an A7CR since the primary use case of extra resolution for cropping isn't going to come up for me for at least six months due to my personal situation

Like new used A7CR’s are down to $2300 on our buy & sell board here, and new has been in the $2450-2500 range.

One thing to consider with the A7CR vs. the A6700, using the Sigma 500/5.6 as an example (which I own and it is stellar!), you essentially have a 500-750mm zoom equivalent on the A7CR. That fullframe 500mm view can come in very handy when shooting quickly moving wildlife especially birds where it is all too easy to have a wing or leg accidentally cropped off in the heat of action (easy to do if you had the A6700 and the Sigma was always a 750mm equivalent crop), or when you need less magnification for being close or having a larger animal as the subject.

Also, I recommend anyone considering an A6700/A7CR camera to get hands on it before buying, as the ergonomics in hand is very much an individual thing - some on here love the tiny size and smaller controls, and others of us could not effectively use them because they are too small for our hands.

Adding: check the comparable weights of the exact focal length lenses you are wanting. For example, I prefer a 35mm on fullframe as a single prime walkaround lens when exploring a town or Disney-type venue, and the lightest option is the Samyang 35/2.8 at only 80 grams, whereas if I were using my A6700 I would need a 23mm or 24mm due to the 1.5x crop factor and the lightest available is the Sony 24/2.8 at 162 grams - thus negating part of the weight savings of a smaller camera or an APS vs a fullframe.

Yep - it's worth keeping in mind that, in some focal length ranges especially, the A7C option can practically be smaller and lighter than the available APS-C choices. Take the 45mm focal length, for example. You can either have an A6700 with a Sigma 30mm f/1.4 (giving an effective spec of 45mm f/2.2), or you can have an A7CR with a Samyang 45mm f/1.8. The Samyang is cheaper and lighter than the Sigma. And it's a nice lens.

The immense depth and breadth of the Sony full-frame lens lineup creates a lot of options for nifty combinations. There is often a good "but I want it to be small, despite it being full-frame" option.

Total cost of the whole system (mainly/especially because of the cost of the body) is the biggest argument against just going the full-frame/A7Cx route, rather than the APS-C/A6x00 route. But if the budget is there, it's kind of just... better.

p.1 #15 · p.1 #15 · A7CR or A6700

As others have said, the a6700 and a7CR are similar from many aspects. Sony has been parts consolidating a lot for scale and volume purposes. For instance, the rear LCD is shared between the two, but the EVFs are unique (A7CR being superior). Both a6700 and a7CR have about equal weather sealing, which is less than the rest of the A7 lineup (for instance, there are no seals on the bottom of these cameras whereas the A7IV does).

Also, for stealth pet/kid photos, rolling shutter is far lower on the a6700. For fully-electronic shutter this makes the a6700 usable for at least moderate motion (1/40), where the A7Cr is only good at static (1/10). Because of this the other main differentiator is that 4K video quality should be much better on the a6700, since the A7CR needs to line-skip to keep full-frame 4k readout.

I would agree with the "handle first" recommendation. Not everyone likes the smaller bodies. If I were to guess, the finder is the "problem," if there is one, for some. Of course, there are some features and controls that can't be fit into the smaller bodies. For "travel," I do find the small bodies fit more easily into some bags more readily. When a maker says it's "mirror-less" bag should fit x number of bodies and lenses, the A6700/A7CR might be more likely than an A7riv, for example to make that squeeze. That's a shared advantage for the A6700 and A7CR.

"Which lenses?" is an individual sort of thing. I've put the 28-200 on my A6700 for handling comparisons. I thought it a tad big but I'm used to the aps-c 18-135 on the small body. OTOH, I like the 70-350 on both the A7Riv and a6700.

I'm not a primes all the times user. I have the 30/1.4 Sigma mentioned and it's a fine lens. But at 45mm angle on a crop body/crop setting, kinda long, doesn't get lots of use. OTOH, I recently added the Samyang 24/1.8 and like it on both ff and aps-c uses.

Comfort-wise, my 300GM and 1.4x are about as long and heavy a lens as I'd want to use on the 6700 handheld for long periods. It's a little awkward, but totally manageable when necessary. Once the 2x goes on, the monopod comes out. Most of the time, it's got the 70-200GII or 100-400GM on it, and neither of those push my comfort level with the set-up at all. The 200-600 would give me pause and likely have me reaching for the monopod. It's the rough equivalent of putting Fuji's 150-600 on an X-E4 body with a small additional grip. You might find the rV + 200-600 combo more manageable.

At the wider end, I can't recommend Sigma's 10-18/2.8 highly enough and the 18-50/2.8 is solid as well.

p.1 #18 · p.1 #18 · A7CR or A6700

I bought both the A6700 and A7CR within the last year, replacing my A7III and A7RIV. AF speed and accuracy, subject detection, and IBIS is better on the compacts by a large margin. I mainly use the A6700 for wildlife at the Salton Sea and aviation photos, usually paired up with my 100-400 GM, which becomes a 150-600mm. Plus I use the 1.4x TC when longer reach of up to 840mm is needed. No need for the Sony 200-600 bulk and weight, the 100-400 does it all for me.

The A6700 has some advantages over the A7CR when using longer lenses: It has a 11FPS shutter speed instead of 8, it is a true mechanical shutter and the sensor readout speed is about 4 times faster than the FF body, thus fast moving ground level jets bypasses rolling effect is greatly reduced. Its grip is slightly larger and more comfortable, plus it has a built in, but removable, rubber eyecup which I find very useful on bright sunny days. As the A7CR/II came after the A6700 I don’t see why Sony made the mistake of not having a flexible eyecup design on the FF compact bodies like the A6700 has.

I like having the 61MP body and use that for most travel, nature and portraits. But for the smallest and lightest kit with general photos I take the A6700 with the Sony 15mm f1.4, Sigma 18-50 f2.8 and 90mm f2.8.

A7CR or A6700

In between there is A7C II.

As somebody using A7rV as main care, I feel that A7C II is a balanced camera. In practice the resolution is adequate for almost everything and high ISO images are visually pleasing and easy to post process.

The body is just too small to be used large tele lenses. For that kind of work A7IV is a better choice - if A1 is not an option. A7rV has good af and image quality, but I feel it is too slow for serious bird photography (and A7cr would not be any better).

In general I have love/hate relationship with the A7c II. Image quality and af are good. It is also refreshing smaller that A7 cameras, this makes a difference when using small lenses. However, EVF is only marginally acceptable and screen should up/down (or be same as in A7rV). Larger grip would also improve the camera. Buying A7cr is not an answer to any of these concerns. And frankly, in terms of real photography, jumping from 33mpx to 61mpx does not make that big difference.

Neither...A7rIII. I am trying to make the same decision as far as having a travel camera goes, and
well, in the past the A7rIII served me incredibly well. Images on my wall are beautiful. I'd pick up another one for cheap instead of an A7cII or A6700. Plus, I love the 42mp. AF is certainly adequate for landscape and street photography.
