Olympus Zuiko 9 - 18mm

[tomcat]

And... for those who are interested, the diagonal AOV for 9mm on a Four-Thirds DSLR is 100° 30'.. still wider than the 12-24mm for Canon and Nikon. But not as wide as the 10-20mm lens though.

Sample pictures shot with v1 9-18mm:

Problem is no one is posting sample image of 9mm, and then taking the same picture with one of the kit lenses (14-42, 14-45, 14-54) at 14mm to show how much wider the 9mm is...without a reference ALL of the sample images I've seen so far have been USELESS!

That's not true. And by FOV, I presume you are actually referring to Angle of View
The 7-14mm does provide the widest FOV for APS-C/Four Thirds type DSLR system.
The 7-14mm on a Four-Thirds DSLR actually has a diagonal AOV of 114° 12' at 7mm focal length
The 12-24mm lens on the Canon APS-sensor DSLR has a diagonal AOV of 96° 21' and 99° 36' on a Nikon APS-sensor DSLR at 12mm focal length

Even if we consider the Sigma 10-20mm ultra-wide, the diagonal AOV on the Canon and Nikon is 106° 35' and 109° 41' respectively at 10mm focal length.... nowhere near that of the 7-14mm on the Four-Thirds DSLRs

You can check the AOV for any focal length and any sensor size at this site:
http://www.imaginatorium.org/stuff/angle.htm

By the way, the sensor size for the various DSLRs as given in dpreview are:
Canon: 22.3mm x 14.9mm
Nikon: 23.6mm x 15.8mm
Four-Thirds: 17.3mm x 13.0mm

Hi Tomcat,

I am actually referring to Sigma 12-24 on full frame shd provide the widest disgonal AOV, it actually provide 122 degree view. where as 7-14 only 114 degree.

That would be good. Should add in the 11-22mm for comparison as well? :think:

As an option, sure along with the Sigma 10-20mm, but most people will have had experience with one of the three kit lenses all starting at 14mm...even if they sold their 14-XXmm lens they can still relate to it.

Check this review out. It's got the comparisons.

No it doesn't, it's about the 7-14mm lens, not the 9-18mm...totally different price ranges for these two lenses and the amount of rectilinear correction makes a difference.

The mm of a lens isn't everything...if it was the 7mm would be wider than the 8mm fisheye.

So which IS the widest then? Is it still the canon 12 mm - on the FF dSLR?

 

[phyrewall]

A friend who attend the Olympus workshop last night says that the unofficial word about it's price will be around SG$600 more or less.

read from other forums, I think malaysia someone got quoted at RM1980 but only available early Nov'08.

Impressive lens. Though I highly doubt that S$600 price tag considering that its already going for 450GBP. Even if you take away the VAT of 17.5%, it'll probably still end up around S$1000.

mm... the distortion at 9mm looks pretty bad, and hard to correct...

Hopefully, Olympus Studio will be able correct the distortion automatically...

 

[dorts]

The distortion looks pretty complicated. I think it will be harder to correct. :think:

Here's a link to another Forum with good photos of the 9-18 as well as several samples...

I am just wondering if in the photo below
http://www.biofos.com/esystem/_img/9-18/test_9.jpg
the blue line was straight (use ruler) and the lense distort it, or it is drawn freehand. What confuses me is that they distortion is not symmetrical

The size of the Olympus lens is smaller than the Sigma 10-20mm tat i bought recently...
