24-70 ZA + a700 sample pics
« on: January 23, 2009, 05:45:36 PM »
Here is a sample of the 24-70 with the a700.  The photo is at 40mm f/4 in front of a window on a cloudy, snowy day.  Fill flash was used.  These are silk flowers.  The silk is very fine and nearly imperceptable unless looking extremely closely.



I see a nice smooth bokeh both in the foreground and background.

I also took a picture of the same scene at f/2.8.  The bokeh was even smoother and creamier, but the entire picture was also just a touch softer.  I liked this one slightly better.

Here are a pair of 100% crops.  One captures both foreground and background bokeh, while the other shows the actual focus point.





This lens can be a killer!  More and more I am sure that bokeh depends a lot on lighting, and here is an example of how soft the out of focus areas can be with good lighting with this lens and camera combination.

Here are a few more.  Again, soft white cloudy and snowy window with fill flash.

First at f/4



Now at f/2.8



There is a direct shine, but again, with soft light it is not nearly as objectionable as had it been bright sunlight.

Just my opinion.

Nice detail, and I love the soft bokeh. Just makes me want this lens even more!

Thanks Dan.

If you look at the 100% crops at the end, you will see that there are virtually no CAs.  There is just a touch on the very dark meets the nearly white, but they are less then 1/2 pixel wide!

Hey Bill, if I were you, I'd be boxing that puppy up and shipping it via snowmobile up here to me. You have no conceivable use for a Coke-bottle-bottom lens like that. ;)

Oooooo .. it looks pretty sweet. Thanks for sharing.

Thanks Clive!

Every day I am getting happier with my two lens setup.

Bill,

There's a lot to be said for two or three lenses. I still want a faster tele and would be happy with a prime 400/4. But for 95 percent of my pictures these days I too am using two lenses, the 16-80 and the 70-300 ... ...neither are fast. The 100/2.8 macro gets used on occasion. Not been using the 500 mirror much of late, but probably will again in spring in my blind..it is crisp at close range. For a lot of us, two (or maybe three) lenses are totally adequate.

Clive,

I am not married to a 2 lens kit either.  If a really good 200-400/3.5-5.6 G SSM came out, I'd be very tempted!  :-D

Speed really helps.  Our cameras have an extra sensor that really speeds up AF if the lens has an aperture of f/2.8 or larger.  It makes a big difference.  It also means that by f/4 the photos are very sharp and fully sharp by f/4.5 or 5.6.  I rarely shoot anything slower than f/4.5.  If I am really looking for extreme sharpness, I may stop down to f/5.6, but that is about it.

On that note, f/2.8 is expensive by 200mm.  Anything over that and I know for a fact that I have to get slower.  I could never afford even a 300/2.8, much less a 400/2.8.  That is why I would love to see a new 200-400/3.5-5.6 G SSM with a 77mm filter.  It would complete my system and it would be all I could afford.  It would be about the same size as my 70-200 G SSM with a 2x t/c attached.

I am now reading that the a900 begins to produce poor results at f/11 and smaller, due to lens diffraction and how the sensor captures it.

On the wide side, I would love to try a 12-24mm zoom, but it is probably not practical as I am not big on really wide angle.  The 24mm focal length is about as wide as I can really see myself using.
