Ray has already shown you an outstanding example of the 24 (which actually acts as a 36mm on his D7000). Here's one with it at close range which is how I like to use it. My plate was full the other day!

Hey Guys I shot in the studio today, and I have been grabbing one MF lens each session. Here is one from tonight's session with the 85MM F1.4

Matt


Matt you're very good in the use of lighting, nice image. This is what the 85mm was really made for.

Last night the sky was so clean that this was possible with a 1280 x 1.5 (D7000) = 1920mm telephoto wide open:

Even though f/11 or f/16 will deliver slightly better results, this is to show how this lens is good wide open even with a TC.


Jose, great moon shot! With your style of shooting, I bet you're looking forward to any new DX cameras Nikon may be bringing out.

Been crazy at work - but I've been following the thread. Didn't quite catch how it started but I got a great laugh over how exclusive and unfriendly you all apparently are....lol.

James - loved the misty pano and the pumpkins shot.
Phillippe - glad to hear about the 85mm purchase.

Ben, welcome back! Someone was wondering where you were just a few pages back Nice cruise ship pics again.

Bert, very nice family and home pictures.

Leighton, a lot to thank for just in that plate

Here's another pic that I found from the Conowingo outing. The out of focus eagles are an adult and a juvenile. This is a couple towers on a small isle in the middle of the river. There's usually action on and around the towers and the distance (maybe 300 meters?) is less of a burden on my setup and skills

Thank you Monty, Samy, Bert and Leighton.

Yes Leighton, I would love a D400 with 24Mp (for cropping even more), since birders almost always need cropping

Samy, nice "framing" of the BIF eagle.

Jose, the moon's upside down! Superb again!!

At that magnification you should try some of the planets. I believe you should be able to see the rings of Saturn and a pretty good look at Jupiter.

Samy, I even tried hard Jupiter with the same setup of the moon above, but never managed to get a good picture/exposure showing the belt

Jose, the 4 Jupiter moons are fantastic.

Not sure about the belt, maybe try exposing a bit less? Have you tried working with highlights/exposure in post processing. This is way beyond the limits of anything I have gotten to. With a Celestron reflector telescope a few years back, I could just barely (wasn't 100% sure) see the belt. I have to go back and check since its gathering dust in the garage, but I think it was 1200mm or so of focal length. I did see the Saturn rings fairly clearly once with that telescope.

Three more, hopefully the last ones from Conowingo Pay no attention to the dust spots!

Hi Ben. Nice angle of view! Looks like the ship just slid down the streets and into the harbor.

Yes Samy, I have tried underexposure too, but got no success. I am not expert on PS, but tried some sliders also with no success.
Some day I will experiment the 800 + tc20EIII + TC201 = 3200mm to see what I can get.

I'll have to catch up tomorrow. I really need to go to bed, but I've spent much of the day and evening processing photos from yesterday and need to post one photo before turning it.

As I mentioned there were two babies present, one a bit over two months old and one ten days old. Here is a photo of the youngster on his father's lap... Shot with the 85 f/1.4 AI-s at f/2 in manual mode because of the poor lighting. Post processing was a challenge for that reason as well.



Mother and dad are researchers in the medical field, both with Ph.D. degrees, both working at UC San Francisco and both from Finland. They told the story yesterday about the birth of their child. Husband and wife share an interest in rock climbing and are in extremely good physical condition. When Maikki began having contractions, Ville, her husband was at the laboratory where there is lousy cell phone service and terrible land line service. Eventually she reached him and he rushed home. They proceeded to WALK the five hundred yards to the birthing center where she had the baby. When it was time to leave the hospital, they were told they could not be discharged until they produced a car seat for the baby. The fact they'd walked to the hospital and intended to walk home was beside the point. Ville had to walk home and bring the car seat back before they would release mother and child... who then walked home as Ville carried the car seat.

I'll share more photos from the day, but not until I've caught up with what I missed over the last two days. Now to bed!

Wonderful image! f/2.0 was a perfect choice! THe little guy's face is in focus and the rest of the pictures is just enough out of focus to draw my eye to Jr. If PP was difficult it sure doen't show it in the picture. THe colors and white balance are spot on. Again, wonder work!

THe great story just makes the whole thing that much better! We don't just share pictures here, we share our lives!!!!
Thanks
Monty

Worth trying Jose, based on my limited glimpses through a telescope I think you are in the correct range already and the planet and its moons look reasonably circular.

I wonder though if adding more teleconverters worsens coma and degrades the image at those extremes? 3200mm is quite something though. I checked online and its seems to say 2000mm would be sufficient: http://starizona.com/acb/ccd/advimagingplanet.aspx

It maybe that the reflectors don't lose as much light and detail as the light passing through the many lens elements of a photographic lens (+ teleconverters), so maybe 2000mm in a telescope world is different?

Monty's an astronomy club regular, maybe he may have some thoughts or could ask there.
