But unnecessary. Almost every post on UHH would require some grammatical clarification but it's not necessary because most of us are smart enough to figure out what is being conveyed and we don't have to resort to being English teachers. No disrespect to English teachers. Some of my best friends are English teachers.


Really? Perhaps you should define 'us'!

I think what this fellow was trying to say is if you shoot a picture with a full frame lens on a crop sensor body you are not getting the full frame the lens has to offer. i shoot Nikon so I'll explain from that point. I shoot full frame lenses also on a d7200 1.5 crop sensor, that means that for instance, The sensor is designed to shoot at 1.5 mm of a full frame lens. example. On my camera, my 50mm f2 becomes a 75mm because of the crop sensor. my 135 mm prime becomes roughly a 202mm lens due to the crop. A 300 mm lens becomes 400mm and so on. So I think he may have been trying to say that you are not getting the full potential out of your lens. in order for you to get a full frame shot you have to stand back further in order to compensate for the cropped image. I believe the cannon is a 1.4mm crop sensor. somebody, please correct me if I'm mistaken. the lens does not loose any quality or cause an inferior image. it is just a smaller frame in view. That all there really is to it.

Canon is a 1.6

Its interesting to read the difference between Canon shooters and Nikon users.
The urguments have been circling lens quality
for years. I doubt trying to convince some other guys equipment matters much. Clarity between
compact zooms ofter get thrown into the mix.
One thing I noticed while shooting both Canon an Nikon zooms is the softer focus areas at mid point in the zooms travel. Its well known by portraits shooters that either end of most zooms design by picking one end of the travel or the other - such as 70 f3.5 will soften as the extention tube lengthens. Some zooms with a larger nano coating on 4 elements does allow more light at better color consistancies.
If you have questions check out the lens chart on dpreview and pull up the tests charts.
Canon and Nikon have been showing how light bends with different element construction.
One common answer is less is better. This idea
applies to fixed lens verses larger edif glass on
Nikon iris. Canon solved some of this with large
Iris glass or low dispersion glass, since Canon bought the glass MFg from the Germans. They had a hold on the this process for almost 55 years. So if you like packing around a sport lens 2.8 - 200 -400 zoom at 14 pounds of aluminium casing. Then have at it. But pro spirt lens are extremely expensive. Most shooters rent them because of the price. Few guys can afford these lens whether Nikon nor Canon. One thing I do like about Canon is they ad lighter gear an more color saturation with lets say a 500 mm 4.0
But Canon always had harnass problems with their cramped prisum system. Its why I carried Nikon for far less repair problems. But I did use both professionally. Backed both up do to failures. Less choices with these newer short or compact zooms only render fair sharpness at the mid point of travel. So most guys I talk to at events use one end or the other of the zoom for best results. Mid focus maybe soft even poor.
Yoou choose what works for your shooting.
Don't worry so much about what is best. Get the shot. That is the idea.

The size of my eye glasses will never change the quality of the glass they are made of. Where on my nose they hang will not change the quality of the glass I'm looking through.

You may believe, but you would be wrong in your beliefs. Time to do a little more research, your intent is good but actual knowledge a little limited.

The only way to mount an EF-S lens on a FF EOS body, film or digital, iis to modify the lens by removing a baffle that prevents the lens engaging or by using extension tubes and so on.

Secondly, your categorization of EF-S lenses as "low quality consumer line" is very wide of the mark. There are low quality lenses in the EF series, and some very high quality lenses in the EF-S line up.

Finally, there is no such thing as a kit lens. A kit lens would have to be something that would have to be and could only be bought in conjunction with a camera body. At least with Canon, they do not exist. There are good lenses and less good lenses, expensive and less expensive lenses, high build quality and lower build quality lenses, but no "kit" lenses per se.

You seem to think that 'L' glass is good glass, which it is. So if an 'L' lens is bundled with a 5D ml IV does that make it a "kit" lens and therefore worthy of derision?

Please research your information properly prior to posting misleading information or "alternative facts"!

The term "kit lens" has come to mean that it is the lens bundled with the camera when you purchase them as a kit.

I am a beginner; when I first heard that a 200mm lens mounted on a crop sensor was equivlent to the focal length X the crop sensor size, that didn't make sense to me. After researching this I found out that the correct term should be angle of view. That made sense; so words do confuse beginners..

And your point is?

If you read my post slowly and carefully you might find that I said that, and that any lens of any grade can be included in a bundle, so the term "kit lens" is for most intents and purposes meaningless.

It really has no worth as a value judgement.

You said there is no such thing as a "kit" lens and then contradicted yourself in your next sentence. Canon cameras can also be purchased with a "kit" lens.

You are only using part of the L lens and you are much better off getting a crop lens...please watch and note this is only one of many tutorials.

The outcome is a softer image.

We are talking semantics, there are lenses that are included in bundles, but the lens does not change if it is not included in a bundle or is separated from a bundle.

The phrase "kit lens" is used as a derisory term and as often as not inappropriately so. Many of the lenses included in bundles are excellent, some are not. The term "kit lens" has no meaningfull value other than being derogatory.

I have already suggested that but many are too interested in argueing trivia to listen.

In your mind it might be a derogatory term. It is simply part of a kit which is a collection of items that are packaged together.
