What is a manual lens?
When a lens is manual, does it mean that it lacks autofocus?..

That pretty much spells it all out..

That would be a manual focus lens. It could still have an automatic aperture...

It could mean various other things too. For example modern lenses have electronics that communicates the focal length and aperture to the camera which can use this for exposure or shake-reduction purposes..

Without this data, you could lose not just auto-focus but also some or all of the auto-exposure modes too.Regards,Peter..

Depends on the age, and type of the lens, as pointed out already..

But remember, too, that most autofocus lenses have a switch on them, or, less often, on the camera body, that lets autofocus lenses be used without the autofocus system. Just twist the lens to focus it..

A truly manual lens can be found on cameras that date back to the late fifties and early sixties..

Cameras would use an external lightmeter, either fixed to the body via an additional shoemount or handheld..

One would than rotate the diaphragm ring to carry over whatever reading the lightmeter would give to set the correct combination of lens opening(diaphragm) and shutter speed on the camera, via rings on the lens and/or camera body..

Focussing was entirely manual of course and simple turning the diaphragm ring gave an accurate view of the depth of field..

The next major step was that pin which would close the diaphragm blades to the calculated setting, just priot to triggering the shutter.If you think most of this is chinese or hebrew, you belong to the digital age...

He read about the manual lens in the lens manual...

Hi,.

Usually it means you can focus it manually (and perhaps it has AF - look at Canon and you'll see a little switch for MF or AF). And usually you can set the aperture by turning a ring around the lens tube. Have a look at the Leica Digilux 3 f'instance..

They were normal on lenses going right back hundreds or years before they'd invented film but still were using camera obscuras... And someone thought how can we fix the image permanently, and here we are..

No auto focus.no auto exposure.it will not fit on ANY auto focus camera!.

For that Canon in the picture, your closing statement might be correct: manual focus Canons had a very different mount (FD) than the current auto focus bodies which use the EF-mount..

However: on for instance Nikon or Pentax cameras, older MF lenses will fit without any problem on the latest digital bodies. You can even get great results with them and what's more surprising: on the higher end bodies metering will still work and you even get focussing information in the viewfinder....

Ain't life great if you're using a camera from a firm that doesn't change mounts every once and a while!?.

There's no problem so big that you can't run away from it!..

Hi,.

Nice to see a camera that's been used and is still capable of churning out pictures. I must post a picture of my old Pentax K1000..

BTW, has anyone a full frame camera with an adapter for the old L39 thread lenses? I'd love to borrow them for a week or so but think buying them would mean selling all the old cameras first... Trouble is they ain't worth selling but still take pictures. It hits hardest when you see cameras up for sale on market stalls for a pound or so that you're still using..

I of course was talking about that particular lens in that photo..

Ahh.but still not all of the lenses will work on all of the newer bodies!.

Anything less than the D70 or D80 will not work with most of the manual focus Nikon-mount lenses..

Matter of fact, the Nikon D40 and D40X absolutely will not work with ANY old manual focus Nikon mount lens, even though they will fit on the body..

Ain't life great if you're using a camera from a firm that doesn'tchange mounts every once and a while!?.

Yes.back in the day I was one of those Canon users who were upset (can I say 'pi$$ed') that Canon left those of us with the FD system out to dry.but I eventually got over it!.

However, look what happened to Nikon by staying with their old tried and true lens mount.just about every newspaper and magazine in the world dropped them like a bomb as the new Canon autofocus lens mount focused much faster!.

And now, 25+ years later, as Nikon is finally catching up with autofocus lens speed, most newspapers and magazines are still shooting with Canon's!.

But.this topic thread is not about arguing over which is better.Canon or Nikon.so let's not go there!.

I know.I bought this one brand new in 1989 for $2500:.

A couple of months ago I was looking around on Ebay (never buy from there.just like to look), and saw the exact same setup in mint condition with a 'Buy Now' button for $265 (US)!.

At least mine has character marks.LOL.

Notice how on the left side of the camera (right side in photo) that there is no brassing by the camera strap holder?.

I had the PC socket fixed a couple of years ago as the flash sync was off and when I got it back I almost had a heart attack as the character marks are gone with that new body cover on the side..

Ouch, that must have hurt! Marks like these give old cameras their character and their charisma..

I will not go into any debate about Canon vs. Nikon, they both build great cameras and for me it's a matter of personal taste, style and feel that decides which camera you choose: BTW, I have chosen Fuji and Sigma. There hardly are any really bad cameras left anyway, except for all the nameless brandless qualityless junk with 47.8 Mp and 71x digital zoom that finds it's way to the unknowing through petshops, pharmacists and home shopping channels..

One little point however: the D40 will allow you to use old manual lenses, get some old pro grade ED Nikkor and the quality could amaze you. However, you won't get metering, focus confirmation, etc. and will have to work out all settings for yourself. Same goes for the D50, D70, D80 and D100. The D1's, D2's D200/300 and D3 however wil retain full metering capabilities (including matrix metering) and focus confirmation..

Same goes (as far as I know) for old FD-lenses mounted on an EOS with the use of an adapter: metering will work normally..

Hi,.

Well, Pepys said there was truth in "Old wine, old wood and old friends" and I guess it's still true: 'though I wonder how many think/know he meant old wood for the fire....
