the EF in EF lenses stands for electro focus

Electro optical system and it is pronounce eeeos, rather than E O S

Also in Greek mythology, EOS was the goddess of the dawn. From her island home of Aiaia, in the river Okeanos, she rose up into the sky each morning in a golden chariot drawn by winged horses scattering the dark mists of the night with her rosy brilliance

or do I need to buy a Sigma convertor?

Has any one got practical experience of these combinations?

TIA

Simon

I know from personal experience when I moved from an EOS5 to an EOS3

Simon

T2 mount for Canon FD.

Look on the B& H site. They will probably stock them.

***

Canon EF 135/2.8 SF

Obvious advantage - it's an EF lens, everything will work.

Disadvantage - I don't shoot portrait. My understanding is that even with SF set to 0, it is softer than other 135 lenses - I like sharp.

***

You've been given duff information. Every review of the 135 f2.8 sf says that with the soft focus turned off, it's a bitingly sharp lens.

I'm sure one of the custom funcions will allow this

eg cars, beer, rugby and camera bags, English is best and go for a Billingham! Their 335 and 445 bags are both very good.

Simon

In black and white, everyone's a hero

in their EX range they have:

500mm f4.5

800mm f8

50-500mm f4-6.3

300-800mm f6.6

I've met at least pro wildlife photographer who found the image quality of the Sigma lenses to be good enough to produce imges that sold.

Simon !

Yes

All EF lenses are compatible with all EOS cameras, both film and digital.

The only incompatibility is the EFS 18-55mm which only fits the D300 aka the Digital Rebel.

Tokina and Sigma offer some reasonable lenses at reasonable prices. For example Tokina offer a 80-200 f2.8 at about 1/3 the price of Canon's 70-200 f2.8 IS.

Same story for Sigma's 70-200 f2.8.

Tokina also offer a 80-400; Sigma have a 135-400, 170-500 and 50-500.

I've met one professional wildlife photographer, who obviously depends on selling his images to make a living; he was happy with the image quality of Sigma lenses. I've also been to a lecture by a FRPS who used a Sigma 50-500 for bird photography. His slides seemed sharp enough.

Simon,

go for a tamron lens, as you then use it on all those bodies if you buy the appropriate adaptall mounts

How much are you paying for 2cr5 batteries.

7dayshop have them at low prices approx GBP2.00 each plus postage

They proved to be mathemeticians. They got round the problem by using logs!

I'll get my coat

Tokina 20-35mm (not the ATX version) Seemed OK but got rid of it when it needed rechipping to work with an EOS3. This lens has been superseded by a 19-35mm

Replaced it with Canon's own 20-35 f3.5-4.5. Very happy with this lens. It's also had good write ups in AP and Practical Photography.

If this is not fast enough, then Tokina make a 20-35mm ATX f2.8. This was also highly rated by the reviewers.

In the UK these were availible in most good Canon dealers. If memory serves me correctly, I paid about GBP10 in Tecno in late 1990 for one of these. I originally bought mine for my T90 and kept it along with the remote release when I switched to the EOS range.

It's compatable with any T or E series camera that use the T remote connection

If they are Vivitar lenses look for "N/AI" on the lens mount. If they have this then they are AI lenses. If they have "N/F" then they are not.

N/AI = Nikon AI

N/F - Nikon F

1) its an auto aperture setting for cameras that have a program and or shutter speed priority mode.

You need to set the lens to this A for these modes to work.

Essentialy in this setting the aperture is set by the camera rather than on the lens itself.

2) this button is not a DOF preview; rather it's for alignment purposes when mounting the lens. You align this dome with the lens release button on the body. It's to facilitate lens mounting in dark conditions

It normallly refers to the aperature setting

Let say you have a f2 lens on your camera

f2 is the widest aperture. This is also known as fully open.

The aperture ring will also have the following numbers marked on it:

2.8

4

5.6

8

11

16

22

The larger the number, the smaller the aperture

so going from 5.6 to 8 is closing down by one stop

going from 11 to 5.6 is opening up by 2 stops.

The pictorial effect is that the larger the aperture (eg f2) the shallower the depth of field, and the larger the number (eg f16), the greater the depth of field

hope this helps

Simon

A step up rings allows you to put a large filter(eg 72mm) on a small lens (eg 62mm)

A step down ring allows you to put a small filter (eg52mm) on a large lens (eg 58mm)

The terminology is lens to filter

Lens adaptors; each manufacturer has its own lens mount Canon, Nikon, pentax are all different. A lens adaptor allows you to fit say a Nikon lens onto a Canon body

Power booster. In the case of Canon this is an extra battery pack that allows the camera to run off AA batteries or a rechargeable pack, rather than 6v lithium camera batteries and also allows a faster advance speed. In the case of a Canon EOS3, without a booster the max adavance speed is about 4 frames per second (fps) with the PBE2 it rises to about 6 fps and if you then add the rechargeable battery pack it rises to 7 fps

If you want to buy in the UK, get hold of a copy of AP, find the lowest prices and then go into your local branch of either Jacobs or Jessops. They should match these prices in AP.

Can't comment on ther import route as I haven't taken it yet.
