Hello, I have a K10D, so Far I love it. IMO, it's a great camera. I have 2 lenses for it, they are SMC DA lenses 18-55 and a 50-200mm. These are cool but I am looking for variety. What lenses can I get that will work with my K10D? I have no clue. I really want something with a good zoom, the 200mm is nice but is there anything out there that will go a little farther without breaking the bank? I don't really know much about terminology with lenses. I have been learning a little here and there but the acronyms on some of these lenses are killing me.

this lens seems good for me "Sigma 70-300mm F4-5.6 DG OS" will it fit my camera? and what the heck does "DG OS" mean?

thanks for anyone who feels like replying! I am open to suggestions. Also, looking for a good camera bag. I'll take suggestions there too

Hi Matt

'DG' lenses are large-aperture lenses with wide angles and short minimum focusing distances. Where there is wide of peripheral illumination, they are ideal lenses for Digital SLR Cameras. They are usually a lower cost lens mainly due to the large aperture - f4.5 for instance. In very simplistic terms the lower the f figure the higher the costs of the (glass), - lens.

'OS' indicates that the lens has Optical Stabilsation = a feature built into the lens that aids in reducing camera shake in hand held situations.

The Sigma 70-300 will fit Pentax, providing that you purchase it as a Pentax mount.

Hi Matt,
As explained above the DG lenses anre for DSLR's, ie, Crop sensors, you dont need the OS version as the K10D already has this built into the Camera,

You could have a look at the lenses I am selling, I have a Sigma 100-300 at a decent price.

Sorry, but you're being given inaccurate information. DG simply means they are compatible with full frame. DC means they are not compatible with full frame and for crop sensor only.

So, DG lenses work with crop DSLRs but will also work with 35mm format cameras or full frame DSLRs (not that Pentax do one currently). DC lenses will not work with 35mm or full frame cameras.

Your K10D is a crop sensor DSLR so can use either DG or DC.

No need to further confuse things by discussing apertures. Sigma do the 85mm f1.4 which has a large maximum aperture. Contrary to what Paul said. a small number is actually a larger maximum aperture. But DG has nothing to do with that.

EDIT: Interesting that Paul has quoted from Sigma website. So, they don't exactly help with their explanation.

If funds are tight you might want to consider older lenses.
I had a 500mm mirror lens (Manual focus & fixed aperture) for many years, but found the F100-300 (a bit heavy) generally gave better pictures, both are often seen for under 100.
The DA55-300 is a cheapish & reasonable quality modern lens to consider too...

Must go to work.

What is DG?
These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras.

Hi Paul. Just seen that and was editing my post as you posted this. They aren't exactly helping with their explanation are they

While the 15mm DG certainly has wide angles, I don't think my 150-500 does. And while the 30mm or the 85mm f1.4 have large max apertures, again my 150-500 has not.

Hi Alan

No they are not, they could be more explicit! However it does help in some ways if not fully technically correct

They dont offer any explanation to OS in relation to whether or not the camera body itself has Image Stabilisation, merely to offer that the lens has this capability. Which in some ways you can understand as it would involve them in other product brand technicalities/marketing implications.

This is for sigma lenses,from their web site.


APO (Apochromatic )
In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.
ASP (Aspherical)
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.
OS (Optical Stabilizer Function)
This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting by hand held camera.
HSM (Hyper-Sonic Motor)
This lens uses a motor driven by ultrasonic waves to provide a quiet, highspeed AF.
RF (Rear Focus)
This lens is equipped with a system that moves the rear lens group for highspeed, silent focusing.
IF (Inner Focus)
To ensure stability in focusing, this lens moves the inner lens group or groups without changing the lens' physical length.
CONV (APO Teleconverter EX)
This lens can be used with the APO Teleconverter EX. It can increase the focal length and will interface with the camera's AE (automatic exposure) function.
EX (EX Lens)
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
DG (DG for Digital)
These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
DC (DC for Digital)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction.

Reading the original post again, I see you say you want flexibility...
So some other options to consider beyond longer telephotos:

A fast 50 (or wider) prime for low light shots? Depending on type (Manual or auto aperture/focus) These can be had from ~20 to ~150+

A Macro for ultra close-ups From 50 for older models.

Ultra wide angle/Fisheye typically >300.

Any lens with a PK mount can be used with the K10D (or any Pentax DSLR) lenses having M42 screw mounts, T2 mounts, or Adaptall2 mounts can be used with suitable adapters.

Earlier mounts (PK rather than PKA)along with nearly all adapted lenses will require manual apertures (green button for metering) and manual focusing.

PKA mounts (A series lenses from Pentax & third party ranges) give auto aperture (when the aperture ring is on A) but remain manual focus.

Auto focus lenses should all work fine, wether screw type or ultra sonic (USM/HSM). Pentax F & FA series were designed for film but fit this group. DA lenses are designed for digital (Due to lower coverage they often wont usually cover a 35mm negative)

Some thing to look at is the Pentax 55-300,I have the sigma 70-300 which is not too bad but reading from the different forums the Pentax is better.

What sort of photography do you do, or want to do? Portraits, landscapes, birds, architecture, macro....?

Ideally you'll be looking to buy a lens that will improve what you're already doing, or enable what you want to do.

As you've already seen, lots of choices.

well I was looking at nature shots, they are always cool, I like bird photography but I also like landscapes

I am not even sure what macro means.

looking to get a decent wide angle too.

I know it sounds funny, but as an artist, I want it all. the more of a palette I can choose from the better
