Can someone explain DSLR lenses to me?




Elizabeth


Can someone please give me a crash course on lenses? I recently just bought a Nikon d40x and have the basic [18-55mm] kit lens, but I want to upgrade on lenses so I can get better picture results.

Say if I wanted to get a 50mm 1.4 lens... what do those numbers mean? I really need some help and understanding.. I mainly want to do portraits.. but i'd still like a lens that isn't limited to just portraits too.

Also, What would be the best lens for me to get next?


Thanks!



Answer
TBH, you don't need a crash course on lenses, you need to learn more about the basics of photography.

The lens you have is absolutely fine for a heck of a lot of photography and getting a different lens will not get better picture results except in certain circumstances. For instance shooting sport or wildlife where a long lens is required.

Without meaning to be rude, you obviously know nothing about the basics such as exposure (you wouldn't ask about the f stop if you did) so the best thing you can do is go to your local library or book shop and get hold of a couple of basic photography books.

This will guide you through the basics of the camera, lenses, exposure, light, composition etc.

Alternatively - here is a search on "photography basics", have a look through them.
http://www.google.co.uk/search?hl=en&q=photography+basics+tutorial&meta=&aq=0&oq=photography+basics

I am not having a go at you for asking the question but it is a bit like learning to drive. You need to know the basics of what to do and how to do it before you think about buying a Ferrari.
You are likely to get answers on here which go into too much technical detail and that is not actually going to do you any good initially.

have fun learning though.

How to set up and use a Canon 650D digital camera?




Geb


How can I set up a new Canon 650D digital camera and what are suitable hardware and software that I could buy to use with the camera to view, edit and print my photographs.
Also explain how to set it up and maintain it.



Answer
Explain how to set up and maintain the Canon DSLR. Tells me that you bought a DSLR because everybody on this site told you too. Now you are faced with how to operate the darn thing. Simply put you bought more camera than you should have. Well the only thing is to make the best of it.

LETS ADDRESS YOUR QUESTIONS FIRST:
1.You should not get into editing beyond the simple cropping that processors offer for now, you have enough on your plate. I always use a store in my community for most of my pictures.. I do not go into their store except to "pick-up" my order. I use their web site to crop, & order my prints. I don't like putting my memory card into machines that have been abused by every "Tom, Dick & Harry!"
COMPUTER UPLOADING: buy & use a memory card reader ($6.00) instead of the camera to computer cord that drives people nuts.
2. Hardware; there is no hardware to buy now or ever. If you are referring to lenses, you do not have the experience now to go out and spend money on lenses that YOU really don't have a need for yet.
SOFTWARE: you should have connected your camera to your computer for any up dates to your camera, when you first got your camera. Make this a once a year project. When I connected my camera, the web site updated the cameras software so I could use the (then) new SDHC memory cards.
3. Set the camera up and maintain it. Starting backwards unless you use some other size battery you should get yourself about 3 sets of double "A" rechargeable batteries. The best brand are Eneloop. Buy together with a battery charger is the most economical way. If you have a different size battery buy two extras batteries, or at least one. Keep batteries charged , what ever size you use.
4. NECK STRAP- Yahoo does not like it when I use capitals all the time BUT this is perhaps the most important thing you can do. Always wear the neck strap. You drop this camera, be warned-dropping is NOT covered under warranty! The camera belongs in two places only, around your neck or in the gadget bag! Not carry by it's strap in your hands (like that blasted Nikon commercial implies!)
5.Auto setting, most people who own DLSR's recommend against using the "Auto" setting. But I recommend YOU use it until you become familiar with your camera.

I also recommend you invest in some easy to read books by Scot Kelby. He writes in a very easy to read style. I have a few because at first digital was foreign to me coming from a film environment.
The really nice thing about his books beyond the understanding factor is his web site. He often refers you to his web site to make visual presentations easier to understand! This is a real plus for me.
And while we are on the subject of reading you should check amazon for a good book on your model camera. Instruction books are often hard to read because it seems they do not employ "tech" writers anymore and you are left with what is left.

That is enough on your plate!

Good Luck

P.S. I just read "Jim A's" advise on the manual. He is correct but I take it one step further. I download and PRINT the manual, leaving out simple things I already know like putting batteries in the camera etc. I take the remaining pages to a large place like Staples and have them cut and spiral bind the rest. I carry this home made manual with me should I encounter a situation I am not familiar with.
All this editing and preparing also enhances my knowledge of the camera and I find I have less & less to refer to. And while I am on my soapbox, get your backside out there and shoot and shoot. Experience is the best teacher!

What camera should I buy? Also can someone explain the differences between Nikon and Canon?

Kathleen E


I am a photography student and I am looking for a good intermediate dslr camera. I am familiar with the Olympus E-PL1 and I have been shooting with the Pentax K-1000 for a year now. I am at that time in my studies were I am switching from film to digital and need a more professional camera. I am looking for a good overall camera that works well in most conditions. I would like to stay in the $1000 price range or lower. I have been looking at the Nikon D7000. Any thoughts?


Answer
Of course there are differences beyond ergonomics, Canon use old sensor technology, Nikon cripple their entry level DSLR cameras (doesn't apply to the D7000), both charge extra per lens for image stabilisation, Nikon charge extra for auto focus on their entry level models.

Why not the Pentax K5? All your Pentax lenses will work as designed, all will be image stabilised as it's built into the camera, it has functions not available on the Nikon, such as Tav mode where you set the aperture and shutter speed and the camera alters the ISO, multi frame up to 7 images in one frame both with and without exposure compensation, capture in focus is another function unique to Pentax and it uses the same sensor as the Nikon D7000, but the Pentax imaging engine gets slightly more out of it.

Compared here, I'm comparing them with a full frame Canon 5D Mk11

Chris

I will say that video is very much an afterthought with Pentax (not much better with Nikon - but some), but as a stills camera it can't be beat for low noise high ISO stills within it's price range, very nearly (and I really mean very nearly) as good as my Nikon D3s which is a full frame low pixel density camera specifically designed for low noise images in low light, at 4 times the price.

Chris

Whats the difference between these two cameras?




itsmebekah


Whats the difference between a cannon dslr camera (t3) and a cannon power shot digital camera? Other than the price? I am looking to get a cannon camera, but im a total newbie with cameras and i need your help.... All i know is one is $550 and one is $350... Thanks!


Answer
The DSLR has a lot larger sensor (over 10 times as large) and can capture more light. More light means better low light performance.

And just as important, the lens is immensely better on a DSLR. Not only in it's light gathering capability, but also its optical clarity, quality, and having fewer defects (all lenses do have some defects though).

And there are a lot of other highly advanced features in the typical DSLR that no compact camera has; full manual exposure capability, FIFO buffer (results in low shutter delay), a real shutter (electro-mechanical), phase-detect focusing, but to name a few. They are too numerous to mention - so go to a camera shop and have them explain the features.

Lenses and depths of field on DSLR cameras?

dslr camera lenses explained on Nikon Dslr Photography Tips
dslr camera lenses explained image



Sabasaurus


I'm looking at a DSLR and I'm noticing the camera lenses. Can someone explain to me the differences in them? Does one particular lens only work for certain aperatures? Will a f/5.6 lens give me ONLY a shallow depth of field? Or will it give me any type of depth of field?

Hopefully I explained that right.

Thanks for any help.



Answer
Main lens information is focal legth and apperture.

If you see a lens with 70-200mm f2.8-5.6 it means that the lens focal legth only goes from 70 to 200.
Now the F numbers at the front represent the minimum amount of aperture you can get at that focal length. For instance at 70mm you can get anything from 2.8 nothing below. This means that you can get 2.8 3.5 4 5.6 onward. Not at 200mm you cannot get any f-number below 5.6.

Some lenses have fixed aperture. For instance : 70-200mm f2.8. This lens can keep the 2.8 all the way from 70-200mm

Then there are the fixed (or prime) lenses. These have both fixed. For instance, the classical 50mm f1.8. These lenses cannot zoom but provide the best looking pictures in therms of quality and, since they don't zoom, they can have really low numbers aperture with amazing depth of field.

As for the depth of field question, a lens that is f2.8 will give you any field from f2.8 onward.

How do I take good photos of sky lanterns?




rb


There's a sky lantern festival happening tomorrow night, and I really wanna take some good shots of the lanterns as they take into the sky. Does anyone have any good settings on a DSLR camera for shots like these? (I own a Canon 500D). Thanks!


Answer
I'd use my Nikon with it's 35-80 zoom lens set to 80, that the best camera I got right now but it's definitely not adequate.

I used to own a Pentax K-1000 with an assortment of lenses, still do but they're wore out and won't work anymore. Now if you got something similar to a Pentax system---try to do this.

Use ASA 1000 film as I assume you'll be shoot at night, 200 for day. Using a 75-260 zoom lens and bracing yourself against something solid like the roof of your car to avoid hand shake track the subject and shoot.

I recommend you use a flash attachment. The flash won't really carry more than 15 yards but it will reflect and expose an image behind it's principal source of light.

I use a flash to explain UFO's and often I get helicopters and F-117's and when I know what they are they ain't UFO's anymore.

Good luck and good shooting.

Hope you win a prize in "Popular Photography".

Whats a good camera for great pictures but no experience in photography?

dslr camera lenses explained on nikon d60 compatible : mongran
dslr camera lenses explained image



Laly


I like taking pictures, especially of my kids. I want to buy a good camera for those priceless moments. I don't know a thing about cameras or photography but I love looking at those professional photos and I would love to get those results on my photos. Someone suggested the Nikon d5100 but I have been reading and the dslr cameras don't have a lot of zoom. I would have to buy an extra lens to get a good zoom and even with an extra lens, I wouldn't get a great zoom like some other cameras like the canon SX40 Hs (35x). I know that they are completely different type of cameras. (Honestly don't know why). But I would like to know what kind of camera would be good for me, even if I need an extra lens, for me to get amazing photos and a good zoom for taking far away pictures (soccer games, etc). Please explain in plain english because again I know nothing about cameras. :-/


Answer
"I don't know a thing about cameras or photography but I love looking at those professional photos and I would love to get those results on my photos."

It's not the camera, it;s the person behind it that is important. The camera is just a box and some glass that aptures light. the PHOTOGRAPHER is the one that decides what light get's captured and how the box captures it.

The camea doesn;t know anything about composition (ok so a couple of them are able to guess at the rule of thirds), the cmaera won;t know if the person's pose is bad, the camera won;t know that moving 3 feet to the left will give you better light ... you, as the photographer, have to see this before you press the shutter. YOU make the decision of what to include in the scene, when to take the shot.

No camera, will give you good results if you don't learn about photography ... none at all. all you'll ever get are porrly composed snapshots that are porrly exposed because you are letting the camera do the thinking.

Just to give you an idea ... this is the tpe of picture i was takicng when I got my first DSLR.

This is what I shoot now:
http://flic.kr/p/appbzY
http://flic.kr/p/dmngSV
http://flic.kr/p/dmngWo

What has changed over the last 6 years? My understanding of photography.

So that being said, pick up your D5100 ... see if you can get a two lens kit (18-55 and 55-200) and that should have you well set in terms of lenses. Then spend a bit on a basic DSLR course and learn about photography ... just don;t expect to be creating stunning images right off the bat.
