Hi guy's what is the point of the apperture ring on some lens, i've just got myself a Sigma 180mm macro lens Nikon fit .When i mounted the lens it came up with error code FEE checked the hand book for my D80 and it tells me set the apperture ring to minimum and lock which i did and the lens works fine.
So what is the point in having the apperture ring or is this to do with my specific brand/model of camera :thinking:TIA From a newbie

It's useful to have if you want to use lens in manual mode.
 
It's probably an older lens which will fit on an older camera too. That way, you set the aperture on the lens ring, then the shutter speed on the camera.

On modern DSLRs you lock it and then set the aperture on the body.
 
Some of my steam powered cameras have a Judas Window which allows me to check ye aperture orifice setting without so much as taking my remaining eye from ye spyglass.

After the age of steam had passed, small crew members were persuaded to forgo rations and squeeze into the lower decks to operate the aperture upon receipt of an electrical signal.

For several years `twas considered unwise to rely upon these junior ranks in times of inclement weather pertaining to the brass monkey.

In times somewhat current, `tis found that a spyglass equipped with ye venerable aperture ring, when utilising a non-automatic setting, willst operate ye electronic flash in the TTL mode favoured in decades past, and not the newer-fangled type. But I digress into the little explored waters of the Kingdom of Pentaxia.
 
not a lot of use on most cameras these days ,,,hence the g series nikons , but on my camera i need an aperture ring to change the f's. ,and you dont need it to use a d80 in manual ,it stays on the highest f stop.
 
Seems strange that Sigma would put it on a modern lens :thinking:
 
As already mentioned, an aperture ring offers more flexibility with the lens if you ever decided to use it on a film body.

It's also quite nice to use when in aperture priority mode, something quite intrinsically satisfying in setting it on the lens instead of a thumbwheel.
 
Thanks for the answers guy'sand girl's:thumbs:
