I've been looking at large glass in Michaels (camera store in Melb.) window for thirty years.Just after I bought the 20D saw the Canon 300mm F2.8L in Michaels second hand window.It was actually a brand new and unused display lens in Japan.Michael's was selling it as second hand.I waited till the grandprix was over and made an offer.Finally got it for $4999.I wanted it more than the IS version as I have heard they are not as sharp.As you can see from the picture the faint stars are all the same size over the whole field,about 2x2 or 3x3 pixels which is about 15x15 micron.The theoretical airy disc size for a perfect optic (ie diffraction limited) at F2.8 is 4 micron.So for a multi element lens it is very good.
I would really like to try it on a full frame Canon the new 5D say.This would result in a field of view of 6.87x4.58 degrees.

One very nice feature of this lens is the whole lens plus camera can be rotated inside a collar on the lens mount.This makes framing an object easy.
Yes expensive, but it performs like it cost.

Sounds silly but @ $5K it was a bargain...Tony http://www.baltronics.com.au hire the same lens for a paltry $165/Day or $384/ Weekend; you would want to be sure of the weather though.

Yes, I guess you are correct it is a bargain, as knocked around ones sell on Ebay for about the same price.Most pro. photographers sell them when they are no longer up to scratch.

By the way submitted this picture to AS&T this morning.

Yes a stunning shot there, pinpoint stars and perfect guiding/alingment. Excellent lens too sharp out to the edges.
I always thought a 20D would do very well by using the "photoshop" noise reduction method as you dont even get amp glow from a 20D as it turns off the amplifier during long exposures

Yes thanks Scott.I had hit a brick wall until I used your method for noise reduction at high ISO.All other noise reduction methods I tried left 'dark holes' where the noise was.The Photoshop method was far better as you have control over the noise being removed.

The Canon lens is superb.The 5M jpg or the 24M Tiff of this picture is even better.Would love to try this lens on a full frame to see how good it is to the edge.
Will they bring out a 5DA?Or will Hutech offer a modified 5D?Just dreaming!

Bert,

What a fantastic image, very smooth and detailed! Looks very sharp all the way across for f2.8. My only other comment is that you have clipped a fair bit of faint detail (i.e your background is a tad dark).

Phil, 300mmf2.8 sells around $7000 new but keep your eyes open for secondhand one. I have also seen a good condition 200mm f1.8 sell for $4000 AUS, that is mean't to be an amazing lens.

avandonk · #33 27-09-2005, 07:23 PM
