That's why the 50-200mm (Zuiko) makes a lot of sense. Most of one's shooting can happen within the range of this lens. Beyond that, a wide-angle is a good choice.

If you shoot birds & wildlife, then you can go for a tele-photo.

In olympus, its 2x magnification. I am not sure if a 100-400(eq) lens is going to fall 'in most used range'. Well, the same 2x magnification on the other hand makes even a 50-200 lens usable for birds and wildlife.

A note to oly users.
When you look at test reports of 50-500, you will get much better performance than tests. This is because you don't use the corners, which are the problem area.
Same lens will perform bad on a full frame, better on 1.6x crop and amazingly on the 2x crop.
You are using the sweet center spot. And even cheap non high quality lenses perform as good as expensive lenses if you look at the image quality around the center.

So the 50-500 may be a problem for the full frame land, or even for the 1.5x,1.6x crop domain, but on the Oly, its amazing.
Oly E-3 + 12-60 + 50-500 = Serious Bada$$ combo!

50-200mm vs 50-500mm = 1070g vs 1,842g

The bigma is not so sharp, especially closer to 500mm. You might get really close shot, but if it is not sharp, it defeats the purpose.

Its not sharp as you go away from center. With 2x you are always close to center.

While checking out the olympus site, bumped into this news item
One step too soon

@kvish, can you explain a little more about what you mean by '2x' here ?

The sensor size is 1/2 of the legacy 35mm film. So a 50mm lens on 35mm film will be like a 100mm(fov) lens on oly slr. This is what he meant by 2x.

Its a crop factor... not sure angle of view also changes from 50mm to 100mm.

@gkrishn, thanks.

If Olympus cameras have a different crop factor, then pls make calculations accordingly. (I'm a Nikon user). I have used traditional /film camera focal lengths in my post.

I'am getting a deal on my credit card on a Canon PowerShot A550 for Rs.6000 (+ Rs.100 for delivery). They are also offerring Nikon Coolpix L11 & L12. But I did some research and found that the Canon A550 is a better camera and would thus like to buy it. I just wanted to know it is worth buying for that price?





I'am not a photographer and I'am upgrading from a Sony Ericsson k790i cybershot phone to a digital camera. I really have no idea about digital cameras and their prices. Hence I was trying to find out if this was a good deal or not?

I still use the previous model of this camera, the A520 (4MP, 4x optical zoom) even though I have upgraded to a DSLR. I am sure you will not be disappointed. But the price may be higher than other brands as Canon charges a premium on most of their cams.

The aperture rating says f/8-16. That means it will be very very soft on the tele end. People are crying foul over the image sharpness at 300mm on a lens with f/5.6 at tele end. I seriously doubt this lens.

Looks like all their lens are ultra slow. Nothing less than f/8!!!!

actually I thought lense for CMOS and CCD cameras need to be designed so that all the incident rays on the CCDs are at right angles to the CCD/CMOS sensor. Film was not as sensitive to this issue. Hence Film lenses are not really suited for digital.

as far as DSLRs go
Oly is a 2 x crop and no FF
Nikon 1.5 x crop as well as FF
Canon has a 1.6 and 1.3 x crop as well as FF
