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^^^

Well, if you have a 300mm lens on a mid format camera, and make a 135 sized crop from the middle of the sensor, you get the same result as with a FF with 300mm lens...

no, we would not have the same results because  the MF lens has much lower resolution and contrast / surface area compared to a 24x36mm 300 lens

Cropping from a 300mm lens instead
« Reply #23 on: February 02, 2013, 06:26:28 PM »

...  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!
So you are cropping from a 300mm, f/4.5 lens to a portion of the image smaller than 36x24mm? Then you might as well use a 300mm lens on a 36x24mm format camera, still allowing a crop to the same FOV. And with more pixels on the same subject matter if the camera is a D800(E), for which there are 300mm lenses far less expensive than the Hasslebald one (and faster).

You will need the smallest crop, for any lens FL, on the Sony A77 or NEX 7, 24MP on APS-C.

I just stumbled upon the Nikon D5200. It is also 24MP on a crop sensor so it is more relevant for this thread.
I don't know the Nikon lineup otherwise I would have mentioned it first.

Yes, I thought of that after I posted: the cheapest and highest resolution alternative to that massive 2.75x crop from a 300mm lens on a DMF body is using a 300mm lens on a sub-35mm format body like the Nikon D5200.

By the way, as an alternative to my previous idea of replacing the 800/5.6 with a 600/4 lens and 1.4x on an FX body, one could replace the TC by a DX format body, and so use half the ISO speed.

I was being somewhat light hearted....since it decidedly was not the right tool for that job, but it was what I happened to have with me when I was in this situation, D3s was back at the hotel....but fact remains that sometimes medium format cropping helps and can still give you something great.

My numbers were based off how I cropped the original P65+ image to get to the final result.

  Just to add to those old thread, and interesting tidbit form Nikon rumours at:
http://nikonrumors.com/2013/02/07/the-new-nikkor-af-s-800mm-f5-6e-fl-ed-vr-lens.aspx/#more-53302

   This is the line that caught my eye:
The lens hood for the 800mm f/5.6 lens (model: HK-38, product number: 4985) costs $1,078.96!

  Now the lens hood IS included when buy the lens for the $18 thousand, but if you ever lose or damage the lens hood, another grand for replacement?  :(

I'm sorry but I think we should all be far more appalled that the Pentax 560mm lens is $7,000 dollars...that seems far more ridiculous then this beeing 17,000 in my mind.....

No one is pleased with the price, but the Nikon and Canon equivalents are at 10k and up, although a stop faster.

I would prefer this Pentax Lens:

Very few of these were ever made: Hasselblad 300mm f/2.8 - mostly because of the limited availability of the glass.  I think they were only $25K when they came out, so the price has gone up some.
