If you're looking for a quick and easy way to measure out camera lens size, and so read on! This is an of import part of photography that many people don't retrieve virtually when they are buying a new lens, filters, or other equipment. Our article will teach yous exactly how to measure out camera lens size.
Past the end of this article you won't have to wonder what your camera lens size is - and you'll be able to make all of your purchases with confidence going forward!
Permit's become to information technology!
Don't Mistake The Diameter Of Your Lens For The Focal Length
The easiest manner to identify a lens is by information technology's focal length.
Some common focal lengths are 24mm, 50mm, 85mm, etc. You lot get the idea.
Some beginner photographers fault this for the diameter of the lens. They and so become confused because when they're looking for equipment for their lens (similar a filter) - they can't discover a 50mm filter.
If this is yous - don't feel bad. Nosotros've all been in that location.
Technically...
An 85mm lens is a lens with an 85mm focal length. Technically, information technology's the distance from the sensor to the signal of convergence - or the bespeak where all low-cal that passes through the lens converges and then passes to the sensor, together.
A basic caption is how broad or narrow your field of view is. A lower focal length value (like 24mm) is much wider than a higher value (like 100mm). Makes sense, right?
That's focal length in a nutshell - don't confuse this with camera lens size or diameter.
**Also, be aware that lenses of the same take different sizes. This can exist because of different manufacturers or different apertures.**
**The images above show the size difference between an F/one.8 and an F/1.2. Overall the GM (second image) is much larger, this includes the bore.**
Diameter Of Your Lens
The moment you pull the trigger on a new lens - your artistic side is thriving, nearly overstimulated. You're imagining all of the amazing photos you'll exist able to take with it.
One matter that is overlooked by most - is the diameter of the lens.
While information technology usually isn't a big deal, there are things that are affected by the diameter. These include:
- Size and toll of filters
- The ability to actually use a filter
The Diameter Of Your Lens Determines The Size Of The Threaded Filter
That's right. The diameter of your lens determines the threaded filter size. Generally speaking, the larger the diameter - the more than expensive the filter will be. Larger filters tin exist harder to find also.
I've included a comparison chart below. It shows how larger filters are more expensive than smaller ones - and they're sometimes out of stock for months while smaller filters go on to be in stock.
Lenses That Crave More than Gear
Believe information technology or not - there are lenses on the market that don't permit traditional hardware or filters.
Wide angle lenses are a common one. Mostly speaking, annihilation below 24mm crave a special mount and filter. This is due to the curvature of the outer drinking glass (popular out bubble). There'south a special mount that attaches to the lens and a filter slides through and is held by the mount.
Another instance would be if the front element is just too big to have filters/mounting. A good instance would exist the Canon 200mm F/1.8 or a 400mm F/2.8. The front elements are too big to accept threaded filters (and if they did, they would be huge and incredibly expensive).
Measuring The Diameter Of Your Lens
You tin do this past measuring it with a ruler or tape. This is a super erstwhile schoolhouse fashion of doing information technology - but, yous'll ultimately know the diameter of your lens.
You do this by taking a ruler or tape and while looking at the front end element - measure out from the very outer edge of your lens (where the threads are), to the other. Do this while passing over the center of the forepart element.
Passing through the center is disquisitional, seeing as if you 'cheat' the measurement (not quite through the centre) - your measurement volition exist off.
Write down what you lot got, and double bank check. Once you're confident with what yous got, that'due south the diameter of your lens threads - and the diameter of whatsoever threaded filter you want to put on information technology.
There Is A Much, Much, Easier Way...
Once I tell you this, you lot may wonder why I even went into talking about the tape/ruler measuring... Well, I want to give you options. There could also exist an example where yous aren't able to use the method that I'm nearly to mention.
The easiest manner is to read the numbers that are on 90% of all lenses, effectually the inner glass/threads.
This number next to the symbol if your lens/thread diameter.
Easy right!! Very.
Now, I mentioned the method from before because this writing can wear off. Information technology'southward basically painted on the lens - this can wear off. If you lot buy a 2nd paw lens that's worn and you tin't read it, you lot now have a method to detect it yourself.
Now, What Tin You Exercise With This Information?
The most common reason for needing to know this information is for lens filters. Hither is a list of filters that do good various types of photography and video. I'll so pause that down and divide them into either photography or videography filters.
Most Common Lens Filters:
*The examples below are amazon links. We are currently working to mankind out this commodity and add together content on each private filter* The Best Variable ND Filter is our latest article towards getting all of these filter types explained.*
- Neutral Density(ND)
- Variable ND(VND)
- Polarizer(CPL)
- Infrared
- Mist
- Macro
- Astrophotography(light pollution)
- UV
- Articulate(for protection)
Mutual Lens Filters For Photography
Common Lens Filters For Videography
- Variable Neutral Density(VND)
- Mist(there are VND/Mist philharmonic filters too)
The residuum of the filters are very specific and are only used for one type of photo or video (similar astro or infrared).
*Lens diameter is information you'd need to know for lens caps too.*
That's It! You Know How To Measure Camera Lens Size!
As simple as this article may seem to some, sometimes information technology'southward the nearly simple of things that people either forget or accept a hard time grasping.
Don't fret! Y'all now know how to measure out camera lens size, both the quondam school way (with a ruler) and the much easier way (written on the lens itself).
You lot can now get all the filters and 'extras' that you lot need with conviction knowing that you know the correct diameter!

FAQ
We talk about this topic in more depth in our article - just in that location are two forms of 'measurement' for a lens. One is its focal length (the number you see on every lens IE 50mm, 85mm). The second is the thread or filter size. This number is found on the front chemical element of your lens (in writing) - information technology's the number yous use for both filters and lens caps.
This would be determined unabridged by the manufacturer and the f/end (aperture) of the lens. This is because, each manufacturer's size (in general) of their 50mm may vary - and lower f/finish lenses accept larger front elements. Meaning, an F/1.8 50mm lens volition have a smaller forepart element than a 50mm f/1.two (49mm vs 72mm, respectively).
