interchangeable lenses and my Olympus C-2100UZ

This is still about my Olympus c-2100uz. If anyone can figure out why I
cannot reply to a post I would dearly appreciate it.

Now, I have several different lenses, filters etc for this camera. Are you
saying that the lenses I have are not considered 'interchangeable'? If
they aren't , would someone please tell me what an interchangeable lens
is? Thank you for your patience.

 

Ok here goes a I hope.

An interchangeable lens means the lens dismounts completely from the
Camera Body to be replaced by another with the same mounting. On the
C2100Z you are using an ACCESSORY lens to compliment the FIXED lens on
the camera body to give you some of the flexibility of the
interchangeable lens cameras. It is a simple distinction often
confused by ambiguous advertising.

The basic lens on the C-2100 is NOT removable you can only ADD
supplementary lenses to it. A dSLR on the other hand has a lens mount
on the BODY of the Camera that permits the lens to be removed
completely and replaced by another.

Hope that helps.

So on the very early kodak digital cameras where there was a relay
lens inside the camera to make better use of the early tiny
sensors. Despite being based on, say, a nikon F90 camera, they weren't
really interchangeable lens cameras?

Interesting question, if it was simply a corrector in the light path
INSIDE the Camera body but permitting the use of existing Nikon Mount
Lenses I would tend to class it as interchangeable. I was trying to
give a fairly simple answer in a gross manner not too tight on the
fine points. It would Still be an SLR in any event since it used a
movable flip up mirror and used the shooting lens as the view finder.

Don't ya love how terms get mushy?

But it's an imaging lens with possibly multiple elements!

Ah, so the pellicle mirror SLRs aren't really SLRs. Damn.

Personally, I think the people who came up with these ridiculous group
definitions should be taken out and beaten repeatedly about the head
with a difficult-to-classify camera of your choice. Particularly the
ones with the expensive point and shoot "ZLR" cameras and their raging
insecurity issues.

And on that I will heartily agree with you!

Dave

 

On possible distinction is that if you change the lens on an SLR or DSLR
you can actually get access to the sensor (or film), and hence changing
the lens can let dust into the system and give you marks on all your
subsequent pictures. The c-2100uz is a "sealed" system optically where
this cannot happen - a plus point!

Cheers,

Actaully most sensors have a glass plate in front of them. On the
other hand, if you're consideringthe c2100uz as a sealed system it
shouldn't be possible for dust to get in between the primary and
secondary lenses, but it is.

Yes, I was considering the sensor and any filter as a single unit which is
susceptible to dust. Note the use of quotes around sealed! It's unlikely
to be completely sealed as in vacuum-tight.

Those are add-on elements to a non-removable lens. They are not
lenses..they are elements.

 

What are you talking about?

I own one of those (a Kodak DCS-460, based on the Nikon N90s):
http://heim.ifi.uio.no/~gisle/photo/dcs460.html
It has a 6 Mpx sensor that which is 28 x 19 mm. There is no
"relay lens" of any kind inside the body - nor am I aware of
any other design using a "relay lens" (whatever that is).

I can't understand what you refer to, unless you are talking of
"microlenses" - which is a feature you find on the /newer/ dSLR
cameras. They are attached to the sensor to gather light for the
photon wells.
