LOL Kinda talk backwards, I apologize

Thank you for helping and confirming about the lenses, this is all new to me and I am so excited to have a new learning curve with things.

With the birding, I love shooting wildlife and especially eagles and birds, so I wanted to get some really head shot macros with the birds being perched on limbs.
Hence why I wanted to use the 70-200 with it as well.

Unless these eagles are tethered to the limb, you won't get close enough to use a Raynox. With your lens set for infinity focus, maximum subject distance is going to be just under 12".

No, it won't, unless you're shooting macro. As Dan said, your focusing distance with the attached Raynox, won't work for getting head shots of birds in the wild. And a miss spoke by someone else, having used both, I've found that the Raynox DCR-250 works best with lenses shorter than 100mm, the DCR-150 works best on lenses above 100mm.

EDIT: these adapters are not teleconverters.

Head shots of birds in the wild? Drop $7K on a DA 560 and learn how to get within a few meters. (Minimum focusing distance 18.37' (5.6m))

The Sigma 150-500 like I have, $800 if you can find one (discontinued), has a minimum focus distance of 7.22' (2.20m).

At that distance it isn't macro...







And it's not a lens you are going to use a Raynox on...

Cropping works well if you have enough MP.

This is cropped to 4.6 MP with the K-5. Distance about 20'. (Maybe less)


This is cropped to 9.6 MP on a K-3. Taken through a window. Distance about 10'.

You're very welcome. Have you considered getting a teleconverter for your 70-200mm? That will increase the magnification in the way you intend.

I brought extention tubes for $3 and they were metal ones, have not figured out how they are supposed to work yet LOL I will check into the converters, is there a certain brand or name I need to be searching for for that?

Thanks for the extra replies and photos and explaining too that makes sense .. the 500-1000 are out of budget for me at the moment :-) But that will be on my wish list for sure

I assumed your 70-200mm was a Tamron or Sigma f2.8, but in your bio you say it is a Pentax. I was not aware that Pentax made a 70-200mm. Is it perhaps the SMC Pentax-F 70-210mm F4-5.6? The lens is important in determining whether a TC will work or not, and how well.

Or the Pentax-F 70-200 4-5.6, which is the same as the Takumar-F 70-200 4-5.6

Pentax-F 70-200mm F4-5.6 Reviews - Non-SMC Pentax Zoom Lenses - Pentax Lens Reviews & Lens Database

There was also a Pentax-A 70-200/4.

If this is the lens you will not want to use a tele-converter.

Your best choice, if you can budget it, is the Pentax-DA 55-300/4-5.8. You can find the DA L version for less than $200. Usually around $170.

Yes, it is the Pentax 4.5 F 70-200 not a sigma or a tameron.

So I will look into the DA 55-300, that would be more in my budget , Thank you for helping me save money too

I did buy the Raynox DCR 150 and should get it next week sometime :-))

The Raynox 150 is a great match for the DA 55-300mm. Just set focus to infinity, zoom to adjust magnification, move the camera closer and further from the subject to focus. Actually all of the preceding applies to your 70-200 as well.
