I went into a Jessops store a month ago to look at the Fuji X100, a very smartly dressed lady asked if she could help, whilst examining the camera i said "its a shame its an effective 35mm lens, as i would prefer a wider angle" rather forcefully she told me its a 23mm lens, after a lot arguing about the effective length of the lens she looked it up on a computer, even after that she said its still a 23mm lens, to prove my point i grabbed a compact camera on display that had a 35mm wide angle on it, the view was the same as the X100.
Today i went into the same shop to look at a mirrorless compact system cam, with the Apc size sensor, the salesman from panasonic said " dont go for that size sensor, this one has a sensor thats 9 times the size of any of the DSLR's" i explained that the 4/3 type is smaller than a DSLR's, i said it might be 9 times the sensor in a compact camera Oh no, they have 2/3rds sensor, i think he has been reading about 2.3 sensors etc.
It given me so little confidence in Jessops, but they are there to shift boxes, so they dont bother with learning about the products they sell.

That`s no different to the EPZ forums, all I`m interested in is the effective crop yet some will argue that a 50mm lens is still a 50mm lens no mater what the crop
Jessops, I`ve had both good and bad experiences, the worst was probably the time an assistant swore blind that the Canon 20D had spot metering, after explaining I was`nt interested he blew into the mirror box before placing the camera back on display
a 50mm lens is still a 50mm lens whatever camera its on, but its the effective length of the lens when it is on a camera with a sensor less than the size of a full frame sensor on the average DSLr a 50mm turns into an 80mm lens (effectively)
the way i explain it is to imagine a circle of 42mm dia, thats the coverage of a 35mm frame, now use the centre point and make a circle about 28 mm dia inside the other circle. inside that put a 2p piece, you will now see that it fills the frame of the DSLR sensor, the smaller one, but in the 35mm frame it needs to be enlarged to fit. both are using the 35mm lens but the smaller sensor only uses the centre part of it. the smaller sensor is closer to the rear of the lens than a 35mm sensor would be, so the light rays have not spread out the same.thats a rough guide.

There we go, I really can`t be bothered
We should talk in terms of Angle of View but nobody ever does!

My thoughts exactly Paul...
Paul - you believe that putting a 50mm EF lens on and EF-S body changes its focal length ....

I`m only interested in the final crop, nothing else matters, I`m not interested in the nerdy gobbledygook.

Depth of field?
People who grew up with film cameras who instinctively know what an 80mm lens will allow them to see can do that math and get some meaning out of the 1.3, 1.6 etc calculations when talking about 50mm lenses on crop cameras,
To someone who has only ever used a DSLR crop camera it's meaningless.
If I look through a 50mm lens I see the same magnification as I see with the naked eye (none). I see that whether looking through the viewfinder of my 10D or my 5D. I know than a 100 will be more magnified and a 17 less magnified than reality.
This is pretty off-topic though aren't we meant to be slagging off sales staff?
On the subject of sales staff, I'd much prefer they said they didn't know, that they weren't sure instead of trying to bluff their way through everything. I've heard some appalling rubbish in Comet, PC World, Dixons over the years. Jessop's didn't used to be so bad
I walked into Jessops a few days ago, the staff were all over me like flies on a turd, I left pretty sharpish.
In the Dublin branch they talk about Four Turds and Micro Four Turds
