In my world the case can be important you have m or M m is for milli, M is for Meg. only about 1,000 million apart I remmeber the first digital camera I used was a ricoh 300,000 pixels was the advert. And a friend of mine was interested in slrs at school but was never allowed under UK law to buy them. He was shocked when I said I'd brought an slr. He thought I'd brought a self loading rifle. in my job TTL is Transistor to Transistor logic in the camera world it was Through the lens metering. What about TTFN? What that was, mostly a war time experssion tatarfornow was what my mum would say I think she got it from the Goons show, but she'd also say lol was lots of love. Nope: Tommy Handley. ITMA. I normaly have to look up things I'm not sure of as we use a lot of such things. Typically surface mount chip sizes which I have to order. TQFN is one I rememeber not to order, SOIC check the studetn knows what they are ordering SSOP TSOP again Q the student, FPGA , SIP, DIP, TO18, TO3, PLCC, CMOS, PMOS. N & P channels aren't TV stations. And as they say, There are 10 types of people those that understand binary and those that don't. -- Regards, Eric Stevens |

Bzzzt! Thanks for playing, but Eric wasn't talking in millimeters, but in a use context. use context does not matter. It sure as hell does to the user. a long lens does not become not long because someone uses it in a different manner. the definition is clear: https://en.wikipedia.org/wiki/Long-focus_lens In photography, a long-focus lens is a camera lens which has a focal length that is longer than the diagonal measure of the film or sensor that receives its image. The Wiki gives two sources. You are welcome to use 'long' in that sense if you want but you weren't the person who first used the term in that sense. It was Tony Cooper. It is up to Tony to define what he meant by 'long' in this discussion. -- Regards, Eric Stevens |

Bzzzt! Thanks for playing, but Eric wasn't talking in millimeters, but in a use context. You have to wonder how nospam mind works. He's been around a photography group for yonks. He knows - you know he does - what people mean when they refer to a "long lens". He knows - he couldn't help but know - that "long lens" is relative term and not a physical attribute description of the lens. He must have picked up that one person's long lens is not necessarily some other person's long lens, but both have a long lens in their bag. He surely must know that the choice of what long lens to buy is largely based on what you intend to photograph. And, of course, cost. He must know that no one will agree with him, that he's not informing anyone of anything, and that there's no point to his comment...but he persists. How desperate for attention must he be? You should see what nospam posts in the Windows 10 news group! Prolific is an understatement. -- Regards, Eric Stevens |

Nope. The discussion is about the term "long lens", not "long-focus lens". nope. they are equivalent terms. If you try Googling 'long lens' you find: "a lens with a long focal length, especially as a camera attachment for taking photographs from a great distance." It also leads you to: https://www.apogeephoto.com/lenses-t...d-short-of-it/ "When photographers use the words “long” and “short” to describe a lens, they’re talking about the magnification the lens provides. A longer lens provides more subject magnification–so you can stand farther from your subject and not have the subject appear too small in the picture." long lenses are also called telephoto lenses, although that actually has a specific meaning. You have tried to divert it to this, but is isn't working. if anyone is trying to divert it, it would be you. He is trying (quite successfully) to stick with his original subject. -- Regards, Eric Stevens |

He also hangs out in the Linux groups. A poster there one time posted that it was unfortunate: nospam is quite knowledgeable about Linux, but his attitude and demeanor turn people off so quickly and completely that they stop listening to him. I have a theory about nospam: He is not a person, but an AI experiment (probably Google or Wikipedia sponsored). 'His' programming calls for him to pick out a word or phrase, take a contrary or narrow meaning, and support it with clips from searches. Note that 'he' has no original content, and frequently uses catch-phrases. -- Ken Hart |
