Thanks for your help...iThe Lens is HUGE...95 cm front element. I still need to use a mono pod as it is effectively a 750mm f6.3 lens. Man do I shake when hand holding. I am used to working between 12-75 mm at most. This IS a challenge. I feel like a novice.

Well Ben, it is really interesting to see you returning to your past. I guess you can go home after all. I know you had a mirror in the past and that you like some of the effects that the circles of confusion create in your work. I would be most interested to see your potential employment of this lens in some future venue.

I would also be interested in the degree of sharpness and contrast that one could arrive at with this modestly priced lens. I have the Pentax 1000mm and the contrast is very good and PF is completely absent and the sharpness is extremely good.

Practice makes perfect on hand holding the lens. I hand hold the Pentax SMC 1000 in bright conditions and can get some sharp images, but a monopod works better and a Wimberley works even better (even though it costs three time the price of the lens ).

Please post when images are available.

Isn't 'Wimberley' the new stadium where those decent chaps in Old Blighty play their famous soccer final, eh what......lol ?

Best regards

How many degrees do you need to turn the focusing collar to go from min to infinity? Also what is the close focus distance?

Is that adapter specific to this lens or are there generic t-mount adapters that will work? How do you like this lens so far? worth the extra money for the extra to gain the 1/2 stop of extra light?

T mounts are generic on the lens end and you just need the correct Pentax mount on the other end of the T mount adapter.

I'm really wondering what's happening to Ben these days. First a 70-300 and now a 500mm. The next question will be "which 2x converter works best with this" and "how do you guys like my moon shots?" Or does this make my ass look fat? (in reference to the shot you posted last year)

Hi Stephen;

How did you know that I shot with a mirror lens in the past. Did I mention that? I am curious. I used the mirror when I lived in Milan, but that was years ago. Do we know each other, have we met or do you know my work. I am curious.

Do you not mean "from this lens"?

Closest focus is 2 meters.

It is almost a stop more than f8.0 it is 2/3rds of a stop. But also less depth of field...YIKES!

As it has been heavily overcast in Paris, I haven't given it a good work out yet. Will do so shortly. It won't be as sharp as a classic lens, but hopefully as sharp as my 500mm Sigma I had years ago.

Peter...I don't know..I wanted to get a reasonably inexpensive lens that I could stick on to my K10D's to walk around Paris with. I don't want to use the K20D's as they are for my pro work. If the K10D gets stolen that is OK, but need to make sure the K20D's I have are secure for my business. That is also why I got the the Tamron. I will use the 16-45 Pentax for snaps as well. As to the Mirror lens, I loved what I got out of the Sigma I had for Fashion Editorial work and might actually try this with studio lighting in a huge long space. My lighting will add needed contrast to give a sharper impression than is really there. I hope my flash remotes will work at the distance required. Remember that the 500mm I had in the past was for film and therefore a real 500mm. This is effectively a 750mm lens in this format. I will need a walkie talkie to communicate with the model via my assistant...Seriously.
LOL

Maybe after all these years the poor canadian abroad is missing donuts.

The 500mm mirror will give him lots of little out of focus ones
