I guess that, at that price point, I'll buy a car instead... but image quality should be OK judging from the computed MTF chart (it seems totally amazing in fact).

Now... the tele-converter comes for free... so it may be a good deal after all.  Huh

Thats surprising for a 35mm lens, but for any lens in general really....I guess when you have a D800e with 36.3 megapixels you need to start producing even better glass...which costs more....

My answer, buy a MFDB and Crop! Crop! Crop! (Just kidding)

http://brianhirschfeldphotography.com/category/hasselblad/hasselblad-lenses/
If you look at the first example, the Lizard, which I bring up a lot because I think that it illustrates what is great about medium format and the things its capable of....the final 40x24inch image was a 275% crop of the original image which was 60mp, I believe I am allowed to do this math but a 300mm*2.75 = 825mm lens .... so bam, medium format 825mm lens which is a stop or so faster then this 17k monster!

^^^I jest a little bit, but still^^^

Nikon $17,900.00 vs Canon $13,250.00 vs. Sigma $7,600.00
All of these are individually way more valuable than my 16 year old car. Eight of my cars equals one Nikon or Canon 800mm lens? Add a Nikon to part of a Sigma, and there's the current "new" price for my brand and model car.
Any way you look at it, if you want 800 mm and auto-focus and high IQ, you are going to pay. On the other hand, if you just want to have an 800mm lens, you could go for one of the RoBoSamyang 800mm mirror lenses for a mere $180.00 (if you don't mind "Donut" bokeh), or one of their pretty primitive T mount refractors for a similar price. I have used the T mount refractor, and you could get $180.00 worth of fun out of it.

Hi,

I have a 400 mm wich I use with a 1.4x or 2x extender. Not like Nikon, Canon or the Sigmonster, but I make pictures with it.

Best regards
Erik

     Considering that astronomy has been an interest of mine for just a long as photography has been, for that kind of money, I could go out and get a top of a line APO refractor with field flattener, all camera attachments needed, and a top of the line EQ mount, and still have some $$$ left over.
     So yeah, even if I win the lottery this weekend, don't think it's gonna happen too fast.

Not so expensive… Canon 1200mm f/5.6 Super Telephoto Lens For Just $120,000.

I remember seeing what looked to be a photographer with a ~900mm Nikon lens on a monopod. I thought he was getting shots of American warships at Garden Island, Sydney. When I got up level with him it became all too obvious. His camera was aimed at Russel Crowe's apartment.

Those far slower, non auto-focus telescopes with far more limited close focusing abilities are hardly comparable, but what I find strange about the Canon and Nikon 800mm, f/5.6 lenses is how much more they cost than the 700mm and 840mm f/5.6 alternatives that Canon amd Nikon already offer: pairing their 500/4 and 600/4 lenses with a 1.4x TC.

After all, any true telephoto lens, meaning one that is physically less long than its focal length, already effectively consists of a shorter lens of proportionately shorter aperture ratio (same effective aperture diameter) with a matched TC permanently attached behind it, the so-called "telephoto group" of lens elements: http://en.wikipedia.org/wiki/Telephoto_lens

FWIW, Art Morris of Birds As Art blog has switched from the Canon 800mm f/5.6 to the Canon 600mm F/4 plus 1.4x TC III (840mm). More flexibility, similar performance.

There's an Italian amateur photographer who wrote an article in Nature Photographer about shooting birds manual focus with refractor telescopes. Manual focus of BIF with perhaps ergonomically not-ideal controls = hard!

A few people have figured out how to attach certain Canon FD lenses to EF mounts. You too could have a vintage manual focus Big White for under $3,000.00. That would be the talk of the town at the school football or soccer meets.

You're right! That's a bargain at $100/mm compared to about $150/mm for the 14mm!  Grin It pays to buy in bulk.

20 elements and nearly $18,000 is insane.

There's an Italian amateur photographer who wrote an article in Nature Photographer about shooting birds manual focus with refractor telescopes. Manual focus of BIF with perhaps ergonomically not-ideal controls = hard!

agreed- but manual focus BIF with good ergonomic controls is not difficult.  These were made with a 2-element 560mm lens on a cropped camera giving a field of view equivalent to an 800mm lens on a full-frame camera:







This lens cost about 8% of the new Nikon 800mm f/5.6.  The Nikon 800's MTF plot is better but for BIF where subject motion requires a fast shutter speed (VR's usefulness is limited) would anyone see a difference?  For distant subjects where dust, heat waves, clouds of mosquitoes and atmospheric crud degrade the image would anyone see the difference?  On long hikes I know I'd see a diffrerence... I can carry the 560 all day.  This 800 would be left in the truck.  As I see it the 800 is useful in a very limited set of conditions.  I'd have to have a very good reason to spend that much on limited-use equipment.

  For what it is worth, I use my 80mm, F7 (works out to 560mm)  ED refractor on my Nikons not uncommonly.     I am quite sure it is not as good as the 800mm Nikkor, and my telescope has a fixed aperture (no internal diaphram like a  camera lens has), but you know something - for the price of the 800mm, I could buy 18 of these ED refractors.

   Again, your mileage can and will vary,  but once you get 300mm and beyond in any brand of camera lens, IMO, you are getting into a real specialty market.   I have a beautiful 300mm Nikkor, but I seldom use it outside of birding, which is not all that often.  If you are covering the Olympics or the  Super Bowl, I can see where that 800mm lens (or something similar) will come in handy, but how many of us actually are doing that kind of photography on a regular basis?

The price is hardly comparable as well. I'm not knocking the Nikon lens, that MTF chart (which is usually the software model not the actual manufactured part) is amazing. I'd say its an engineering masterpiece. At that price it better be.

The brightness out of the f7.5 scope will probably be similar. 6 surfaces reflecting 1/2% vs 40. It adds up.

There is a guy Fernando Batista in Portugal that has outstanding birds in flight shots with a manual focus telescope.
http://fernandobatista.pt.vu/
He uses focus trap, where the camera is set to release the shutter when it detects focus. He turns the scope focuser in front of where the bird is going (distance wise) so it flies into focus.

So what is autofocus worth? To Nat Geo it is probably worth having a couple of these. To most photographers it may be worth re-learning manual focus skills.

I once attended a seminar where a famous sports photographer gave a lecture about his work (pushing Nikon D3), and he was still using manual focus only. He also said he practiced focusing with telephoto lenses at least 20-30 minutes every day. That is one way of approaching it, like a musician...

I would love to have an excuse to own this 800mm and use it.... unfortunately  even 400, 500 or 600mm lenses would be a mere indulgence. I am pretty sure there will not be made a very lot of these but they will certainly find some happy owners.
