Wide Angle or Not Wide Angle
-
I been looking to get my hands on a wide angle lens for scenery and landscape photography and i came across two which claim to be wide angle on adverts.
I wont like the items themselves but i’ll show links to the info pages
This is the first one, its a EF 28-105mm f/4.0-5.6 USM, the seller, (local) claims its a wide angle lens, but i looked up the spec and from what i can see, its not.
EF 28-105mm f/4.0-5.6 USMThis is the second, its a EF 24-85mm f/3.5-4.5 USM and looking at the spec it seems to be the real wide angle.
EF 24-85mm f/3.5-4.5 USMIts hard to judge when using adverts all you have is the sllers word but when they give the name makes it easier to look up the make and model.
So if someone could look at them and tell me, which one is actually wide angle i’d really appreciate it.These would only be classed as wide angle on a full frame body, like a 5D etc. So it depends on your camera.

its a Canon 400D i’m using at the minute. Does that help.
You’ll need a Canon 10-22 or Sigma 10-20 to get a decent wide angle outta that body :wink:
thanks for that :) i’ll have to start looking now then :) now that i know what to look for.
Yeah, that Sigma 10-20 gets great reviews. It is very wide though so might take a bit of getting used to. You can get some cool effects shooting at 10mm though.
pity their so expensive. am still looking at between 500-1000euro for it depending on the make. I love sigma!
It´s very simple, but I make it a little bit complicated to provide you some extra information.
You say that you have Canon 400D. It´s sensor size is 22.2 x 14.8 mm. This means that it´s diagonal is 26.7 mm long. So when using lens which is 26.7 mm long, you will get the “correct” perspective and this will be your standard lens.
Every lens shorter than the diagonal of the sensor (in your case 26.7 mm) will be wide. Every lens shorter than the shorter side of the sensor (in your case 14.8 mm) will be super-wide.
When you have zooms, wide zoom is a zoom shorter than 26.7 mm, standard zoom is a zoom which includes 26.7 mm focal length
What does it say about your lenses? Both are standard zooms, but the shorter end of the second one will give you a wide angle of view.When you look at Canon website, you can see the exact angles:

Diagonal Angle of View: 84° – 28° 30′

Diagonal Angle of View 75° – 23°20′
However they apply to a full frame camera with larger sensor (it´s diagonal is 43.3 mm long) so it´s standard lens will be 1.6× longer.Now if you think there´s too much math; if I don´t want to be precise (anyway there´s no 26.7 mm or 43.3 mm lens on the market), I will apply these numbers to Canon´s lenses. And if I do this, I will see that the 50 mm lens is the standard lens for full frame cameras and 28 mm lens is the standard lens for APS-C cameras (these are the actual and well known numbers that all the photographers work with). Anything shorter than 50 mm on a full frame and anything shorter than 28 mm on APS-C camera will be a wide lens.
PS: Your question really made me laugh. Everybody who has at least the most basic knowledge knows what lens it is because it´s “name” (actually it´s not a name, it´s a physical parameter and it´s the first parameter everybody looks at when he wants to buy a lens) says it. If you say you needed to look it up, it means that you want to buy a 28-105mm or 24-85mm lens without knowing what these numbers mean. And I don´t want to be rude, but if you don´t know this, you probably don´t deserve to own a DSLR camera because you have no idea what it is and how it works. It´s like looking at Land Rover and asking if it´s an off-road – if you have to ask this you obviously don´t know what an off-road is.
So, I hope you learned something new, now you may feel a little bit offended but you may thank me later :wink:
While MMX has given a very detailed response to Dave’s question I feel it’s a bit over the top to stick the knife into him at the end. I’m sure MMX is no different to the rest of us and didn’t know what all the numbers meant when starting out either.
I agree with what Code187 said, your advise while helpful was ruined by your superior attitude. How did you learn about the parameters of the lenses and the camera?
I’ve only been interested, part time, in photography since February and since this is the beginners section i thought i could ask a question, dumb or otherwise, without having some knucklehead judge me unfit to own a camera.
I found your information helpful, very much so, as no-one had explained it so well to me. Although seeing as til now i’ve rarely asked a question and i’ve taken some very nice shots, i figured, i wasnt doing so bad. My main reason for asking was, and if you read my message, i wanted to know which of the 2 had the wider angle since i couldnt get much information on them. And i thought someone here, with experience, would happily share their experience with me, as you did, til you decided to be a big head at the end.
I work with a couple of forums giving advice to people about computers and the like, how many do you think would keep me on if i were to tell each user who asked a silly question, that they didnt deserve to own a pc if they didnt understand how to defrag or change their backgrounds.
I appreciate your math, its cleared alot of questions up, i just dunno why you couldnt give the advice and leave it at that. We all have to start out somewhere and all i wanted to know was which of the two would give me the wider angle.Thanks anyway and i think you need to work on your interpersonal skills a little.
Hi Dave,
I have the canon 400D and i use the sigma 10-20mm, its a great wide angle lense and for about 450 euros new to 250 euros second hand great value. I hope MMX’s stuiped comments have not put you (or anyone else) off asking questions, because we are all learning and contrary to belief we don’t know everything! after all this is the beginners section and you do get some really great answers here. :DThanks Sinead, i’ll keep an eye out of those. 250-450 is well within my price range, i also spend alot of time in germany once a month and i find that they have a much larger selection of camera shops and lenses for alot cheaper then ireland and sometimes even ebay or adverts.
I’m pretty set when it comes to most other stuff, i have a nice 18-55mm and a 70-200mm but for scenery i would love a real wide angle lens as thats what i mainly enjoy taking shots of, play you can get some amazing pictures close up to people with one :)
I’ve recently bought myself a book, old (talks of how 1.3mp canon digital cameras are the best) and i’ve been reading through it, but it mentioned very little about wide angle shots, well no real math or detail anyway.
I wont let him put me off because for all his dickishness his explanation was helpful. I think if i’d based my question differently he wouldnt have had such a superior attitude.
What i’m looking for is a multi purpose lens, something i can bring with me everywhere instead of a bag full of stuff. And out of the two i was wondering which was the better lens, in general not just for wide angle, so my structuring of the question could have been better but still no excuse.
Dont worry i’ll have plenty more stupid questions to ask in future :DHi edg3, no questions on here are anyway stupid and yes you do have to start somewhere. Most people here with any experiance are only too glad to give advice when asked and again it was rather silly out of MMX to add on the bit at the end. Keep asking…thats the only way to learn.

Thanks mate. Aye thats why i asked this is my only real resource for learning. Not many courses on around where i live and when i move i will be looking more into it but at the minute i’m in the sticks so no luck.
Very little else i need help with far as i know but i’ll ask if there is :)code187 wrote:

Then I probably am different because I did. And I would really like to know how can one choose a lens without knowing it. How can I decide whether to buy a 20mm or 200mm lens if I don´t know what it means? It´s like buying a car without knowing what engine it has or if it uses petrol or diesel. I really don´t want to be offensive but sometimes when I read such questions I just wonder “What the hell does this guy want to do with his gear?”
A DSLR is an expensive thing, it´s not a can of beer which you can throw away if you don´t like the taste and buy a different one. If I´m about to spend several hundreds I simply must know what do I want to do, what I expect and what type of lens will do the job for me.edg3 wrote:

It doesn´t matter how I learned it. What matters is when I learned it. And I had learned it before I have bought the camera.

I bought my first camera in January 2008. In March 2008 I got a photo pass to shoot a concert in Vienna. In July 2008 I was shooting a 4 days long music festival with 30,000 visitors.

24 mm vs. 28 mm, this is the only information you need to know which lens is wider. The lower focal length, the wider angle. If you didn´t know it, it means that either you didn´t know what 24 mm or 28 mm means or you didn´t know what “wide angle” means. There´s no other possible answer, sorry.

Have you ever read this? http://www.tensionnot.com/jokes/customer_service_jokes/too_stupid_own_computer” onclick=”window.open(this.href);return false;
I did and I find it hillarious.edg3 wrote:

Because I wanted to motivate you to start learning and actively looking for information instead of passive asking and waiting for answers.
Have you seen the movie “Silence of the Lambs”? Imagine that I am Dr. Lecter and you are Clarice. I could tell you who Buffalo Bill is, of course I could, but you wouldn´t learn anything. And finally, telling you that your question was stupid is still better than eating your liver, isn´t it?edg3 wrote:

Another reason to tell you that you shouldn´t have bought a DSLR. Interchangeable lenses are the main and first reason why people buy (D)SLR cameras. If you want “all-in-one”, then buy an ultra zoom (camera, not lens).

You have access to the Internet, the biggest information resource on the World. What more do you want? Everything you need is there, you just need to find it. And if I can find it, you can find it too. Look:
http://en.wikipedia.org/wiki/Wide-angle_lens” onclick=”window.open(this.href);return false;
http://en.wikipedia.org/wiki/Normal_lens” onclick=”window.open(this.href);return false;Have you ever heard about Wikipedia? I´m sure you have. So why you didn´t look there? The Internet that you browse is the same Internet that I browse (unless you are in China) so there´s no reason why should we look for something instead of you.

Umm… ever heard about reading?
Who keeps asking new questions over and over and over? Small children. Why? Because they can´t read. If the could, they would grab a book and find it instead of bothering their parents every 5 minutes.
Yes, it´s good to ask if you can´t find something, but first you must try to find it, not just sit and wait for others to serve you everything on a silver plate.
