Hello Ron,

You seem to get some very good IQ with the Sigma 2.0tc and the sigma prime. You have gotten me interested in the Sigma 2x for use with the Sigma 500/4.5. I had more or less written the 2.0tc off, because I felt the IQ would suffer too much, but I now am having very good results with the 1.4tc, and your samples leave me in doubt. Did you try the 2.0tc with the 500/4.5? Is that also as good? Would be wonderful to have 1500mm eq. as an option.

regards

Chris

Hi Chris,

I suggest you hold off for awhile for the 500/4.5 + 2X teleconverter. I am still in the testing mode of mine. I havn't had very good conditions to do my tests yet. My first tests, in not so good conditions, are not too good. I hope to get to it soon.

EDIT: BTW, according to some folks on PF and MightyMike of this forum, there seems to be some questions on the autofocusing ability of the 500/4.5 + 2X when used on a K-5 IIs (very bad) as compared to the K-5 (not too bad).

Cheers.

Ron

Great shot Ron! Excellent stuff.

BTW, is it just me or do those horns look like two huge cashews?

There are a couple of other threads I started using this lens if you want to take a look.

Sigma 300mm f2.8

Sigma 300mm f2.8 + teleconverters.

Cheers.

These horns can weigh up to 30 lb (14 kg), while the sheep themselves weigh up to 300 lb (140 kg). A very good read can be found a Wikipedia - Bighorn sheep.

For those that are not aware, the Rocky Mountain Bighorn Sheep is the Colorado State Animal.

Cheers.

Nice shot.  Have you tried that shot with the Q and a 100mm 2.8 yet?  or a 135mm lens?

Just curious

Ron, you've nailed another really good shot.

I'm impressed that you were able to handhold such a setup!

It's still not easy but much easier to do than with the Sigma 500mm f4.5 lens.

Simply excellent Ron.  Incredible shot with excellent clarity for being hand held.  You are a pro with that setup!

Terrific.  Great portrait shot.  Face detail, eye detail, horn detail.

Surprised that it's listed as f/4.0 (wouldn't it have to be at least f/5.6 with that converter - or is there something you can do with the contacts?)

It reads as f4 but exposes as if it is f5.6.

There is no Pentax mount autofocusing teleconverter that passes the corrected focal length or aperture to the camera. The Pentax-F 1.7X AF Adapter requires that you enter an SR focal length when you turn on the camera. The 1.7X AFA will also pass the corrected aperture for many lenses to the camera. However, not all lenses. Many of the Sigma lenses when trying to use with the 1.7X AFA will pass incorrect aperture to the camera, usually it is something that is more wide open than the lens is listed at. Example: A Sigma 500/4.5 when used with the 1.7X AFA will pass f2.8 when the lens is wide open. You can correct this by taping certain pins but not worth the effort IMO.

Cheers.

The image in the OP was taken with a 2X teleconverter. Therefore, it reads as f4 (since that is waht I dialed in) but exposes as if it is an f8.
