DSLR camera lenses?




kajunprinc


i know different lenses create different photos. but which lense is a good all around lense that you can use for many projects? so i dont have to use 5 lenses on a shoot, only one good one. please! doesnt matter which brand or anything. thanks!
im an aspiring photographer, and will be getting a dslr very soon. i dont want to have to go out and buy many lenses at first, i just need one good lense (for now) to get the job done nicely. also i am thinking about buying the nikon d60 or d80.... which would be better? any suggestions?



Answer
Right now the 18-200 mm seems to be one of the favorites (based upon sales in any case).

For my general shooting the 24-70 mm f/2.8 is the best for me. I use it for over 80% of my assignments. The 12-24 mm is perfect for landscapes and architecture. And the 70-200 mm f 2.8 is good for general action, field sports and action like motocross and 4x4 adventures in the mud.

The other lens I use a lot, but is specific to sports photography is the nearly $7,000 400 mm f/2.8.

Eventually as your client list gets larger and your assignments become diverse, you will eventually end up with about ten lenses. If you end up in any kind of advertising work, you may find yourself behind a medium format camera like a Mamiya or Hasselblad ... even a 4x5 view camera ... but time and your clients will influence that more than your personal choice

EDIT:

We have been changing lenses for decades and as long as you don't change the lenses in a dust storm, you don't have to worry much about dust. I have been shooting digital SLR's for just over six years and only twice have I had dust get on my sensor ... Both with swirling dust present, one at an air show an the other at the sand drags.

Besides I think most of the new DSLR's have some sort of dust removal system incorporated within the cameras now ... I know my new ones do.

How to choose a DSLR Camera Lenses?

I have a Nikon D40 DSLR, If I want to make great pictures to small objects what I need to know for choosing the right lenses, because there are several lenses on sale over the internet, some of them are cheap and some very expensive, what is the basic guide? is the optics quality? thanks for your help


Answer
Basic guideline is to stick with the original manufacturers lenses. So in the case of your Nikon, that means Nikon-Nikkor lenses. Nikon once regarded it's primary line of lenses are professional lenses and only gave special designations to their "cheaper" consumer grade lenses. That is no longer a hard and fast rule. Still you will not exceed Nikon optical quality with Tokina, Sigma or any other non-OEM brand of lens.

As for choosing the right lens, that's largely determined by how you'll use the lens and your budget. For small objects shot close up, you are generally talking about macro photography with lenses that allow very short minimum focus distances of only a few inches in most cases. Nikon gives their macro lenses a "micro" designation. At present, Nikon only offers four lenses with such a designation and the cheapest of them at $450 is their 60mm f/2.8D AF Micro Nikkor lens. This actually is a very good macro lens for your D40. The bad news is this lens will not autofocus on a D40 because D40s do not have a built-in autofocus motor like older and higher-end Nikon bodies such as the discontinued D70/70s or current D90. Thats not really a problem since most macro photography involves manual focus anyway.

The only Nikon lens meant for macro photography that will autofocus on a D40 at this time is the Micro-Nikkor 105mm f/2.8G ED-IF AF-S VR lens. This is also a very good lens but, you may find the 105mm focal length to be a bit too tight and depth of field will be practically non-existent. You can often use other lenses for macro photography but some lenses have fairly long minimum focusing distances that can make macro photography difficult at best.

Anthony R


I own a canon point and shoot and I would like to get a dslr that can produce better quality. What are some good entry-level dslr cameras? What about lenses? Any information or tips for a beginner?


Answer
Stick with Canon. They produce excellent quality cameras. And you are familiar working with them.

Look into the:

- Canon XS
- Canon XSi
- Canon T1i
- Canon 7D

Depending on your budget...

The 1st two are entry - intermed. level offerings. The next two are more intermediate (as is the Canon 50D).

What are all these FF55 - 200 stuff on the DSLR camera lenses?

I'm getting a DSLR camera for Christmas and I don't know what all these funky letters and numbers mean.

Thanks in advance!



Answer
Labels, Numbers, They stand for different things.

If you just bought a DSLR you can go to the brand DSLR website and find information about such.

55-200 means that the lens has a 55-200mm focal range. Your kitlens has 18-55, in effect from a group shot to a relative thigh shot. And the 55-200mm is a lens in the tele range meaning it can pull closer for instance a bird in the trees.

Ah you can even see it in effect if you move one of the ribbed rings on the lens you see it extend a bit. Now look through the viewfinder and do it again. Hey wasn't that easy!

The other ring is for focussing, it allows you to manual focus if for instance the automatic focus doesn't cuts it [dark outside or something in the way]

What the other things mean..well that depends on brand and lens brand.

I agree with the others best is to buy a book into the basics of DSLR and read it, keep it with you and most important MAKE ALLOT OF PICTURES. The only way you can learn is through experience! And that means actual doing it.

DSLR's are great tools, but at the same time they are tools, it is the person behind the camera that makes the magic happen. Yes it offers auto modes but one of the nicest thing about the DSLR is control. You get the shot as you desire!

So buy a simple starters guide for your specific model [for instance if you own a Nikon 3100 buy a book that with pictures and easy words tell you what the buttons are for and what does what]

Then buy a book about different types of photography and well again with nice pictures inside so you can see what they mean.

Photography is an art, it is something you can almost touch, taste, feel.. but also it is a technical thing.

So just buy some basic books and actually make pictures. Learn the way get hooked on it.

What are the zoom capabilities of a dslr camera?

So I am wanting to buy a camera, but I don't really know what to look for. I know dslr cameras have interchangeable lenses, and a standard one seems to be 18-55 mm. What does that translate to for zoom relative to a p&s? (Like, is it 30x zoom or something like that?)


Answer
If you are going to spend real money on a DSLR you need to stop misusing words. A zoom lense is a variable focal length lense. 30x is totally meaningless. 30x what? An 18-55mm lense can be set to any focasl length between 18mm and 55mm. Nothing else has any meaning unless you know the dimensions of the sensor the image will be focussed on. Then you can calculate the angle of view options available for a given focal length range.
