Default Confused by lenses, help please?

Hi

I've only ever owned relatively cheap compact cameras. I've decided to splash out a bit and go for a better product, but don't want something as large as a dslr. So I know very little about cameras.

Anyway, I've decided on the Panasonic GX7. It seems to be available with either a 20mm lens

Or a 14-42mm lens. What I can't understand why the package with the smaller lens, 20mm, costs more than the bigger lens.

Can anybody explain please?

Thanks

Don't know much about this particular camera, but a lot of times, the "prime" lens ie the 20mm, often costs more than its "zoom" equivalent as they are normally a sharper lens (better quality pictures).

Don't they have interchangeable lens's?

If you're looking at spending 1k on a camera I'd be buying from London camera exchange or Jessops where you'll get sales staff who know about photography.then ask them what they recommend for the type of photos you'll be wanting to take.

Have a look at Canon's equivalent and Samsung also.

I think it's the prime lens thing, as above.

You can get a Nikon 18-55mm lens with Vibration Resistance for between 60 and 150.

Yet a GENUINE Nikon 35mm F1.4 is 1300......

The photos taken at 35mm with both would be decent with the former and outstanding with the latter.

No probs.
It's the reason why my prime lens for the D300 isn't a Nikon

I bought a second-hand Sigma for 250. Still takes pin-sharp photos.

The 20mm is an f1.7 which lets in twice the light of the alternative f3.5. Primes in general, especially anything going sub f2.8 are very expensive. On that crop sensor its going to be equivalent to a 40mm so its still a very wide lens so consider carefully whether its going to suit your intended purpose. Its wider than "human View" which is 50mm so in laymans terms, if your trackside at silverstone and take an image, the car on the image is going to look smaller in the image than it did to your eye.
