DSLR flower lens size?




Skye Skye


I have a sony a290 with a 18 55 ml lens and I ordered a 52 mm flower lens that doesnt fit.
Should I order a new one? If so what size? so pissed



Answer
Firstly, all you douchebags that say there is "no such thing as a flower lens" are idiots.
Macro lenses are also called flower lenses as that is one of the main things people use them to photograph.
Secondly, all this questions requires is a link to a page full of lenses and which cameras they are compatible with.
Like this:

If you';re just on here to boost your ego by being an ass, maybe you should start writing a diary and keep that shit to yourself.

What makes dslr cameras better than compact digital cameras?




Rachel


i just ordered the nikon d3100 which i believe has about 14.1 mega pixels. my mom just got an olympus compact digital camera that has 14 megapixels, but the quality is horrible. i know that the d3100 is supposed to have great quality pictures, but they have basically the same amount of megapixels, so what makes it a better quality than the olympus?

p.s. for all i know megapixels mean nothing at all...i dont know much about cameras lol im just curious what makes them so different.



Answer
Your DSLR is a larger format camera than your Mom's compact. Your sensors have the same number of pixels, but the compact's sensor is tiny compared to yours. In this example http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/Sensor_sizes_overlaid_inside.svg/500px-Sensor_sizes_overlaid_inside.svg.png you can see the Nikon DX format sensor compared to the compact's 1/2.5 sensor. Because of the size difference, the compact's image must be increased many more times than the DX sensor just to get an image large enough to view, and about 15X just to get to the size of the DX sensor. Every time you increase an image size you also magnify any flaws in the image. Camera format also plays a role in other capabilities of the camera.
There are many factors that affect image quality between cameras; construction, lens quality, sensor design, processor and software design.

How do I know the optical lens size of my digital camera?







I have a camera that has a 10X optical zoom. Is the optical lens size the little number that is written on (by) the lens? f=6.3-63mm?

Sorry. I honestly don't know this. :p
Thank you for your help!



Answer
It will say on the lens something like 5-60mm, 1:2.8-3.4.

Yes, the f6.3-60mm is the focal length of your lens. The second half of that is the max aperture range. at 6.3mm it can use a 2.8 aperture. at 60mm it can use a 3.4. Now it gets even trickier. Your camera has a small sensor. So a camera that has a bigger sensor has a different mm size (focal length) but is the same lens. The 6.3 on your camera is 18mm on a small DSLR and 28mm on a large DSLR and 37mm, 42 and 50mm on even larger cameras. It's all about field of view. You are not seeing further with a lens, you are seeing tighter. A 6.3 lens on a 4mm sensor and 52mm lens on a 6"x7" sheet film both have a (for arguments sake, I'm too lazy to do math right now) 75-degree field of view.

DSLR camera lens question (kit lens-zoom lens)?




Daniel Liu


I have a Nikon D5100, I have a kit lens (18-55mm) and a 55mm lens
I'm planning to sell my kit lens (18-55mm) and get a zoom lens.
either a 55-200mm or a 70-300mm, can these zoom lens do everything a kit lens do and better?

Which lens is better? 55-200mm or 70-300mm, thank you



Answer
Your 18-55mm lens IS a zoom lens. It allows you to get more coverage in tight places since 18mm is a wide angle. Obviously 55mm or 70mm are both short telephotos and not well suited for use in tight places such as an average sized living room. Both the 55-200mm and 70-300mm zooms are budget-priced and perform about the same as the 18-55mm lens you have. If you're serious about upgrading your lens selection save your money for the 70-200mm f2.8 zoom. It is an excellent performer and well worth the extra money.

I'm confused a bit about all this, so how far can a 30mm telephoto camera lens go?


Answer
It depends on what camera sensor you are using, in terms of size.

For standard DSLR crop (1.5x) sensors, its like this: http://www.flickr.com/photos/cajie/364732208/

whats one of the best dslr cameras for macro jewelry photography?




gmanz73


We are a looking for a high resolution dslr camera that can take clear sharp pictures of small jewelry items. What size lens should we look out for? whats a great camera thats recommended?


Answer
Any good camera would do. Its not mainly about the camera but the lens. The cameras i'd suggest are anything in the canon rebel line. You can look them up here:

The lens that i would recommend is Canon EF 100mm f/2.8 Macro USM Lens. Its a great lens for insects, plants and anything that falls in that type of category and would be great for small jewelry too. I suggest you read this review:
