Full Frame Or APS-C For Landcape?

Earlier today I was asked a question about cameras for landscape photography, and since I think the answer may be of interest to others, too, I am sharing the reply here. “Pat” asks:

I have been reading a number of your posts and have to say that I appreciate your balanced pperspective on camera selection….something that is missing in much of these discussions.

I am a landscape photographer that purchased a Sony A7RIIII to complement my A6000. However I have recently become infatuated with the Fuji XT-3. While many Fuji users seem to be more street or travel photographers, I focus mainly on landscape.

I would appreciate your thoughts on the “better” system for landscapes.

This is a pretty common question — whether to hold out for a camera with larger sensor and higher megapixel (MP} resolution or to go with a smaller and lighter APS-C format camera with lower sensor resolution.

“Alpine Lake, Morning” — A solitary sunrise angler stands on shoreline rocks at an alpine Sierra Nevada lake reflecting a nearby peak. (Photographed with a Fujifilm XPro2 and the Fujifilm 16-55mm f/2.8 lens.)

You might think the answer is obvious — a system with a larger sensor and high megapixel resolution is capable of producing images with more detail. However, there are some considerations that turn this into a somewhat subjective question with more than one “correct” answer.

The classic understanding holds that, for example, a 50MP full frame sensor can resolve more detail than, say, a 24MP APS-C sensor. In fact, this is true. If you work with care, using a tripod and a remote release and paying careful attention to things like accurate focus, aperture selection, and camera stability, you can produce a larger print from the higher MP full frame image. So the larger, higher MP system can help if you are likely to produce very large prints .

One of my camera systems uses a 24MP Fujifilm APS-C sensor. I’m absolutely confident that I can produce excellent 20″ x 30″ prints from images shot on this system. But my other system uses a Canon 51MP sensor, and it can go even larger, reliably producing 30″ x 45″ and larger print sizes.

Update (1/15/2023): During the past month I acquired a Fujifilm X-T5, a new 40MP APS-C camera. While my main use for the camera is not landscape, I have now made some landscape photographs with it, and I feel like I have a sense of whether the high resolution sensor is useful in this smaller format. In short, it is. Test images that I have made show lenses I regularly use with the camera are “sharp” enough to produce details that benefit from the higher sensor resolution. If you have an older 24MP or 26MP sensor, should you go out and upgrade? Not necessarily. This is not a “night and day” difference, but one you might notice if you make large prints and look closely. But if you are at the point of getting a new APS-C camera and you wonder if 40MP even makes sense in this format… it does.

So, how large will you print? If your realistic answer is, “probably no larger than 16″ x 24″, you can get excellent results from the APS-C camera as long as you use good technique. In all honesty, you could hang 16″ x 24″ prints from the 24MP APS-C system and from the 51MP full frame system side by side… and no one would notice a difference. The odds are that virtually no one would notice at 20″ x 30”. A very experienced photographer carefully comparing side-by-side prints might see a subtle difference.

If you find that APS-C is good enough — and for many photographers is is more than good enough — this smaller format has some other advantages. The cameras tend to be smaller and lighter. The lenses are also smaller and lighter, partly because a given focal length doesn’t have to cover as large of an image circle. In addition, you get the same angle-of-view coverage from a shorter lens. For example, a 50mm focal length on my Fujifilm APS-C system gives me the same angle of view as a 75mm focal length on full frame. And last but quite possibly not least, APS-C sensor systems tend to cost less than full frame equivalents.

So, yes, bigger sensors and higher MP count can be “better…” but perhaps in ways that you’ll never see. So if you won’t print so large (or perhaps you never print at all) and you value a smaller and lighter system and perhaps saving some money… you could be extremely happy with a good APS-C system, as long as you can find all of the lenses you’ll need for it.

A Question About The Mirrorless Canon R

Reader “Scott” recently wrote with the following question about the Canon R mirrorless camera:

“Could you comment on the Canon EOS R? Your thoughts on mirrorless going forward? I’ve been reading a LOT on Fred Miranda, watching YouTube tutorials by Alex Barrera, etc. I know from reading that the RF glass appears to be amazing. As a trekker, hiker who is looking to maximize lighter gear with excellent IQ, this seems to be a good plan for me. Thanks for your insights!”

In a way I am very qualified to answer this… and in another way I’m not qualified at all! Read on to see why.

For those who may have not heard, the Canon “R” system (currently with two cameras, the “R” and the less expensive “RP”) is a new line of cameras from Canon using full frame sensors, a mirrorless design, and the new “RF” lens mount. While Canon has produced mirrorless cameras with smaller sensors for some time, these new bodies mark the company’s first entry into the mirrorless full frame camera market. Although Canon’s mirrorless cameras arrived late (by comparison to companies like Sony, Olympus, and Fujifilm), it seems that Canon carefully plotted out the path to their release. In addition to these two first bodies, it is all but certain that a high megapixel camera with the lineage of the 5Ds/5DsR will be next, and after that we can expect successors to other Canon DSLR designs.

The mirrorless design eliminates the pentaprism and the “flapping mirror” of DSLRs, and this allows the cameras to be made smaller and lighter. In addition, because lenses no longer need to clear the moving mirror the lens mount can be positioned closer to the sensor plane. This has some potential advantages, especially with “normal” to somewhat wide angle lenses, which can theoretically be made smaller. Canon’s lens strategy with the new mount has two parts. First, all existing EF lenses will work on the new cameras by means of a “pass through” adapter. Reportedly there is no loss in lens functionality, so photographers can continue to use their existing lenses without problems. Second, Canon is fast-tracking the introduction of new “native” RF lenses that use the R mount — and in many cases Canon appears to be making them “best of breed” lenses that exceed the performance of the older EF equivalents.

So, about that “I’m qualified to comment and I’m not” remark I made earlier… I have been shooting with a Fujifilm mirrorless system for about seven years or a bit more, relying on that system for the street and travel photography part of my work. So I’m very familiar with mirrorless cameras in general. On the other hand, my actual experience with the “R” is limited to playing with one in a shop for a short period of time. I cannot report on image quality, and my ability to analyze ergonomic issues is quite limited.

Like almost all mirrorless cameras, the R bodies use electronic viewfinders (EVFs) and do away with the traditional optical viewfinders. There are both pluses and minuses here. An optical viewfinder (OVF) is always a real time display, while an EVF will necessarily have at least some latency — in other words the display will lag the real world. The amount of latency is becoming quite small, but it can never disappear entirely. Some users don’t like (or don’t think they will like) EVF displays. My own experience is that I mostly forget that I’m using one after a short period of use. EVS displays have some real advantages, too. They can display all sorts of useful data right on top fo the image. They show the exact frame of the image — unlike DSLRs which usually are “off” by at least a small amount. They also work really well in very dark conditions, where exposure simulation may allow you to see a scene that might otherwise be nearly invisible.

One downside of mirrorless cameras is that they consume battery power more quickly than typical DSLRs. I might get over 1000 exposures from my DSLR in many situations, but I rarely get 300 with my Fujifilm mirrorless system before I have to change batteries. On the other hand, when I shoot in live view mode — which I usually do when photographing landscapes — battery life is diminished in a way that is about the same as what we get from mirrorless bodies.

Scott’s question is specific to trekking, so let’s look at that usage a bit.

Scott prioritizes lighter gear. Does the mirrorless system provide that? The camera bodies are certainly smaller and typically lighter than their DSLR equivalents, so they look good from that perspective. And for travelers who are constrained by the amount of space they have in bags and suitcases, the smaller body is an attraction. However, if you use large lenses on your DSLR system… you’ll probably use lenses that are roughly the same size and weight on your mirrorless system. So the overall size/weight of your gear many not decrease as much as you expect. However, if you can work with smaller lenses — say kit zooms or small primes — you can certainly get a relatively small system based these mirrorless cameras.

Depending on where you are trekking and on how many photographs you tend to make, the decreased battery life of mirrorless bodies could be a concern. If you are out long enough that you are carrying a charging system, you are probably fine, though you’ll likely have to rotate batteries more often. If you go out for a week at a time carrying enough batteries to see you through the trip… you many end up carrying more batteries with the mirrorless camera. (This can play into the overall weight comparison.)

There can be other advantages to these smaller mirrorless bodies. On the technical side, these bodies have fewer moving parts and rely less on mechanical components, potentially making them more reliable and less likely to break down in the field. On the subjective side, in some situations — such as photographing people on your travels — a smaller camera, especially when coupled with smaller lenses, can make your presence less intrusive and many help you get photographs where a larger camera might alert your subjects and change their appearance.

Finally, the writing is on the wall when it comes to how cameras will evolve in the next few years. That future is almost certainly going to be mirrorless. We may miss OVF displays, but I think we are going to like many of the other features of these cameras. As for me, I currently do half of my photography with a DSLR and half with a mirrorless camera… and I fully expect that five years from now I’ll be using only mirrorless.

About Backcounty Photography Gear

Reader “Paul” asks about gear for backcountry photography and how it may vary from trip to trip:

Dan, I’m curious. On your trips, what percentage of your pack is reserved for anything photographic in terms of weight? And what percentage is camping? Or does that change with your experience and knowing ahead of time what your photographic expectations are?

Great questions, Paul. The answer gets a bit complicated, but let me try to get to the heart of what I think is a question about how much weight/stuff to carry for various sorts of backcountry trips. (A longer article — My Backcountry Photography Equipment — goes into even more detail.)

As you imply in your question, the answer varies — sometimes a lot — depending on a bunch of factors: how fit/young you are, the terrain you’ll cover, your willingness to bear weight for photography, whether your focus is more on miles covered per day or the photography itself, what you’ll do with the photographs after the trip, and more.

Update: A Note About Comments At My Website

By default, visitors to my website are able to comment on posts and articles, and I welcome your comments and questions.

However, earlier this week a reader noted that comments had been turned off on an article he wanted to comment on. That surprised me, but when I looked more closely I discovered that an automatic setting was closing comments a few weeks after posting.

That isn’t what I intended… and I think I have now fixed the problem re-enabled your ability to leave questions and comments.
