What's Canon 328 IS

[JJphoto]

you may already knew or already figured it out.


the other day I visited some photography websites(in Chinese), on those sites, people were talking about Canon 328, Canon 640... at the beginning I didn't understand what they were talking about then figured out they were talking about Canon lenses


Canon328 IS stands for Canon 300mm f2.8L IS


same thing like Canon 428, 440, 456, 540, 640, 856


thinking it's interesting and want to share with you guys

Hmmm.... I guess that's a result of the MSN-generation [:P] I prefer the whole range of name and characteristics myself.

[neuroanatomist]

Well, for Canon lenses at any rate. I can't make much sense of APO DG EX DC HS OSM... [:P]

[Sheiky]

Not to even mention Tamron

what about the 228? is that the 20 2.8 or the 200 2.8? or would the 20 be the 48? :P


Sounds too much like BMWs to me, but it makes sense if it

I think 228 should stand for 200mm 2.8, three digits refers to hundred and last two digits refers to f-stop number, though it's kind confusing with the 20mm 2.8.


not sure about the "48?;P", what does that mean?


and yes, it does sound like the BMWs, especially the 328 IS and the 540 IS[]

They also have nicknames for the lenses. The "big white" is the 100-400, "little white" is the 70-200 2.8, "little little white" is the 70-200 f4. If you add an "s" sound to the end, it

I love it!Their system is much faster and clearer than typing out the entire name of the lens; however, I think it can still be improved further.


First, you use capital letters to convert hundreds:

• Z = 000mm
• A = 100mm
• B = 200mm
• C = 300mm
• D = 400mm
• E = 500mm
• F = 600mm
• G = 700mm
• H = 800mm
• etc.

Then, you use lower case letters for the tens:

• z = 00mm
• a = 10mm
• b = 20mm
• c = 30mm
• d = 40mm
• e = 60mm
• f = 70mm
• etc.

Then you use binary for the ones:

• 0000 = 0mm
• 0001 = 1mm
• 0010 = 2mm
• 0011 = 3mm
• 0100 = 4mm
• 0101 = 5mm
• etc.

So rather than typing out the long and boring "375mm", you just write "Cf0101mm".


Of course, we still need to specify the f-number:

• green = f/1.4
• yellow = f/2
• red = f/2.8
• blue = f/4
• orange = f/5.6
• purple = f/8

The intermediate f-numbers are obvious:

• yellowish-green = f/1.6
• greenish-yellow = f/1.8
• reddish-yellow=f/2.2
• etc.

So rather than typing out the cumbersome and unclear "161mm f/2.2", you can write this instead: "Ae0001mm reddish-yellow" and everyone will immediately know what you're talking about.


But what about I.S., USM, L, II, etc.? Simple, each one of these has a special character:

• ! = I.S.
• @ = USM
• # = L
• II = $
• Macro = %

So a "100mm f/2.8 L IS USM Macro" would be: "Az0000mm red #!@%".


Big improvement, don't you think? []

I'm not sure what other people think, but I bet Neuro will not like it because He can no longer type the letter"<span style="color: #ff0000;"]<span style="font-size: large;"]L"[:@]
