Does Velvet 85 Work On A Crop Sensor Camera
I hear a lot of people in my photography classes and workshops say they want to upgrade to a full frame camera. It seems to be the ultimate goal for many photographers, but why is that? Are you really articulate on exactly what are the differences betwixt full frame and a crop sensor photographic camera?
In this article, I'll demonstrate the difference using side-by-side image examples and try and dispel some of the most common misconceptions nearly why crop sensor cameras aren't as good.
What is full frame?
I'll start with explaining total frame because I remember it's easier to grasp the concept.
Back in the film days, there were many sizes of cameras and coincidentally different sizes of motion picture. 35mm cameras became the standard for hobbyists and even some pros towards the cease of the 90s (I even used 35mm at weddings for blackness and white low calorie-free piece of work).
The size of a frame of 35mm film is 24x36mm (the proper name 35mm comes from the width of the actual film strip including the sprocket holes). But that actual image area of 24x36mm is the same size as the digital sensor inside full frame cameras.
What that means
So what that ways for your application in the digital world is that any lenses yous used on your sometime 35mm film cameras will work and behave the aforementioned on a full frame digital camera (if the mount is the same).
Merely they will not piece of work the aforementioned on a ingather sensor camera (APS-C), though, considering of something chosen roofing power and crop factor.
I'll explain that a bit after in the article, keep reading.
Why aren't all digital cameras full frame?
The short answer here is price.
The beginning digital cameras had much smaller sensors and a lot lower resolution (epitome quality). Equally the technology advanced, manufacturers were able to make larger sensors, ones that replicated the 35mm size and which had increased image quality.
I bought the starting time Canon full frame body, the 5D Classic (it was just called the 5D then) in my urban center dorsum in 2006. It price me nearly $4000 CAD (almost $3150 USD) which was a lot at the time! More than you'd pay for a full frame digital camera now even (the Catechism 6D II is nether $2000 USD).
That's also a lot more than than the Catechism 30D which was released a few months later the original 5D. The 30D at 8 megapixels compared to the 5D which was 13, are both small past comparison to today's DSLRs.
And then while prices have gone down in some areas of digital photography, you can still expect to pay quite a bit more for a full frame than a crop sensor photographic camera. Read my commodity: vii Questions to Enquire Before You Upgrade to a Total Frame Camera Body to help yous decide if you should spend the extra money on total frame or not.
What is ingather sensor then?
You may have seen a chart like this earlier, yes?
It shows the relative sizes of the most common digital crop sensor sizes. For purposes of this commodity, nosotros're comparing the largest (35mm or total frame) to the adjacent size downwards (APS-C or crop sensor).
Let'south see how that applies in the real world.
Look at the prototype beneath which shows the sizing grid to a higher place, overlaid on top of the image expanse of the Kodachrome slide. Observe how much smaller APS-C is compared to total frame.
The smallest on the chart represents the size of a common smartphone photographic camera sensor. So when people say their phone can take photos that are just every bit good quality as your DSLR, show them this!
And so sometimes size does affair.
Simply does that mean that your crop sensor camera is no good? Are the images that you create with your Canon EOS Rebel, Nikon D5500, or Sony a6500 ever going to be inferior? No – permit's have a closer look.
Side-by-side comparison
Ingather Sensor Photographic camera vs Full Frame
In order to demonstrate the differences between total frame and crop sensor cameras (APS-C), I did a piffling shoot with the cameras next using the same lenses.
Often, I observe the biggest confusion most people have is around understanding the ingather factor, and what the heck that really means.
Same distance – aforementioned lens
Full Frame vs Crop Sensor Camera Instance Photos
This series of images was shot with both cameras the same altitude from the bailiwick, using the aforementioned lens. Let's await at how they compare.
The cameras used for this experiment were my Fuji X-T1 (APS-C or crop sensor) and a Canon 5D Mark II (full frame) I borrowed from a friend because I have at present sold ALL my Canon gear!
Wow – what practise notice nigh the two images above?
The one shot with the Canon shows a lot more of the room and the model seems a lot further away, right?
So, you can run across that an 18mm focal length lens on a full frame photographic camera captures a lot wider field of view than does an 18mm lens on a crop sensor body.
In one case again using roughly a 35mm focal length produced very different images with the dissimilar cameras, as seen above.
Finally, above y'all can meet less of a difference between the two images shot at 135mm on both cameras.
Crop factor
Crop sensor cameras or APS-C cameras have smaller sensors, and the resulting paradigm magnification is called the crop cistron – every bit you lot can run into in action in the images above.
It varies by manufacturer (Canon is 1.6x and Nikon is 1.5x), merely we'll utilise 1.5 equally an instance here.
Imagine I took the image shot with an 18mm lens on the full frame camera, then zoomed in on it and cropped part of the image out. Making it roughly 1.5x bigger (like the crop cistron) should consequence in a similar paradigm equally that from the APS-C (crop) camera and 18mm lens. Or does it?
Taking that a step further, you may often hear that the crop gene of 1.5x is kind of like multiplying the focal length past that cistron.
Only it is and information technology isn't.
What it actually ways is that the sensor is that much smaller than 1 which is total frame.
For case, total frame is 24x36mm. Nikon'south crop gene is 1.5x and then past doing the math on that we can figure out that Nikon'south APS-C sensors are roughly 16x24mm. As Catechism'due south is ane.vi their sensors are roughly 15×22.5mm. These are approximations using just the math, not actual dimensions.
But that math does NOT apply to lens focal length which does not modify regardless of which photographic camera the lens is mounted to. A 50mm lens will ever exist a 50mm lens because the focal length is divers as the altitude from the center of the lens (middle of the glass elements) to the imaging sensor or film plane. That does not modify no matter what camera you employ.
Lens covering ability
What does change, is how much of the epitome that the lens is projecting into the photographic camera is actually captured. Recollect I mentioned something called covering power before? This is where it comes into play.
let me explain.
Okay, what y'all see higher up is a representation of how the calorie-free coming through your lens applies to each of the dissimilar sized sensors.
Equally your lens is circular, the image produced by it is too a circle. Your camera captures a rectangular portion of that circular paradigm. Observe how much less of the whole image the smaller APS-C sensors really capture.
Whatsoever lenses that are compatible with full frame cameras must produce a circle or light larger than the sensor, otherwise, you lot'd get image cut-off.
That is why lenses fabricated specially for ingather sensor bodies (chosen Dx lenses by Nikon) will Non work on a full frame camera. This will happen if it were attempted (only they usually won't fit on the mountain anyway).
How this all applies to you
Okay so now yous know, and hopefully sympathise some of the science going on behind the sensor size upshot. Merely you may exist asking some of the following questions:
- How does this apply to me? Is i better than the other?
- Can I still get the same and good photos with a crop sensor photographic camera?
- What happens to my lenses if I upgrade from crop sensor photographic camera to a full frame camera? Will they however work?
The short answer here is that yep y'all can still take great photos with an APS-C or crop sensor camera.
You just take to think and work a little differently.
Same lens – different distance to the subject
Allow's look at another example.
This time I gear up both cameras with the same focal length lens just adjusted the distance to the subject (the Fuji had to be moved back) to go along the model the same size in the frame.
What do you discover most the 2 images higher up? Practise you see any major differences? I practice!
Look at the demote she's sitting on. In the paradigm shot with the Canon, information technology looks distorted and the artillery are exaggerated. Likewise the girl'southward easily look a lot bigger than her face in that epitome than they do in the one shot with the Fuji. Why is that if they were both shot with an 18mm lens? Y'all tell me – what did I modify?
The distance between the photographic camera and the discipline changed the perspective!
The merely thing I inverse was that I moved dorsum to get the shot with the Fuji camera.
Because of the ingather cistron, the Fuji sees less of the scene and then I had to movement dorsum to keep her roughly the same size.
Photographic camera to subject distance affects perspective – the closer you are, the more distortion you will go.
So you can learn something else as a side bonus lesson here – existence closer to your subject volition add more than baloney to the subject, peculiarly on the edges of your prototype.
With an 18mm lens, your bending of view is the same regardless of the camera used. Just you can't see the edges of the paradigm in the crop sensor because well, the image has already been cropped in-camera.
So if I were in the same spot as the Canon I'd accept gotten the same baloney on the Fuji shot, but not the same framing. Does that brand sense?
The ii images higher up wait more similar considering I was farther away from the discipline for both, and the 35mm lens doesn't create equally much distortion. But I run into a few subtle differences. See if yous can spot them.
Pretty close!
I tried to keep the girl the aforementioned size in the frame and using a 70mm lens for both was able to get shots that are very like. Again I exercise notice some small differences, similar a slightly shallower depth of field in the image shot with the Catechism – so let's look at that in more detail.
Depth of field
The depth of field differences between full frame and crop sensor camera is a complicated issue.
I won't go into the science of it here, but suffice to know that you tin go a slightly better shallow depth of field and the much coveted "bokeh" when shooting full frame.
But . . . having said that, personally, I retrieve it's marginal.
Unless you're shooting at f/1.ii for paid jobs that demand it – y'all'll likely exist fine using a crop sensor photographic camera and its bokeh.
Same altitude and aperture – different focal length
My final set of images were shot to bear witness this deviation.
I placed my tripods side-by-side and used a 50mm f/1.8 lens on the Canon and my 35mm f/1.4 on the Fuji. I selected f/2 for both to maintain consistency in the discontinuity for this examination.
Tin you come across the difference? Yes, the background in the Canon paradigm is slightly more of out of focus. Accept particular note of the imperfections on the wall that are near invisible in the Catechism shot but are clearly showing in the Fuji epitome.
Just is that enough to send you running to the photographic camera shop to upgrade? I would suggest you lot concord off on that because in that location are things yous tin do to get a like look to the Canon image.
- Yous could utilize a flake longer lens on the Fuji and support a bit.
- Move the model away from the background a few more feet.
- Employ a larger discontinuity if y'all accept that pick on your lens. (Hint: Invest in better lenses before you upgrade your camera torso!)
There are three factors that affect depth of field and how blurry your groundwork is in your image. I've pretty much named them above, but if you lot missed information technology they are:
- Focal length (because using a longer lens will make you get further from the bailiwick, thus affecting depth of field)
- The distance between the subject area and the background
- Discontinuity
And so it's not only a large aperture that will give yous the flossy bokeh you so desire – all three of those factors must be taken into consideration.
No matter if you utilize total frame, shoot at f/1.2, and use a long lens – if y'all put your model a foot from the background you will NEVER become it out of focus. Menses!
Which brings me to some things that a lot of people go wrong or misunderstand when it comes to sensor size.
3 Common misconceptions about sensor size
- A 50mm lens on a crop sensor camera is the same as 75mm on a total frame body – Imitation!
- You can merely employ lenses specifically fabricated for crop sensor on those camera bodies. Ones made for full frame won't work – FALSE!
- A 35mm lens made for ingather sensor is wider than a 35mm lens made for full frame – False!
I hope that after reading this article you can see why these misconceptions about sensor size are all incorrect.
A 50mm lens on a crop sensor is not the same as a 75mm lens on FF because the lens optics of those two focal lengths are different. You will get something like to using a 75mm lens on FF but the angle of view and amount of distortion is even so that of a 50mm lens.
Aye, you can put full frame (Nikon Fx) lenses onto crop sensor bodies. They volition work, but the view you run into is not the same – as we saw in the examples to a higher place.
But, you can NOT put a lens made specifically for crop sensor (Nikon Dx) cameras onto a total frame torso. They practise not have enough covering ability, and often the lens mount is unlike besides.
No, a 35mm lens isn't any wider on one camera than another.
The 35mm represents the focal length which is the distance from the middle of the lens to your sensor. The angle of view doesn't alter either. The but thing that does change is how much of that image is captured by the sensor.
