Got this lens about a week ago and haven't really had a chance to try it out. Got bored so went out to get some shots. The lens is everything that had been advertised and reviewd, both the good and the bad. It gives really good and sharp images from 70-200mm. At 300mm however the images start to get a bit soft which is a bummer since the main reason i got the lens was for its upper range. It has macro function which isnt bad but macro works only from the 200mm to 300mm range. The macro button allows you to focus closer to the subject arnd 1m instead of something like 1.5m. The auto focusing motor is pretty loud, about the same as the sony kit lenses. It comes with a really sturdy lens hood and a great lens bag which im loving right now.

Here are some example of pics. Most of these (not all) were shot at 300mm at the ISO of 400 with the D80. I'll post specific exif data if you guys request it.


These images were out of camera shots, no crops, etc.

Image

These 2 were cropped for better visibility, size not altered just cropped.

Here are some macro examples

vignette effect from photoshop

This one is a little soft as the auto focus failed to properly judge the focus range. Too close to the limit of the af range.
Image

Take a step backwards and the auto focus works much better allowing the subject to look much sharper.

Very happy with this lens. There is loads of room for improvement but it seems to peform really well for a $230 lens (including shipment).

I am/was looking at this lens but as you say it is a tad soft most of the time. I think I will hold out for the 55-200 F4 L lens from canon its not that much more exspensive from the US.

this is my first post, and only a week ago I bought Pentax K10D and a Sigma 70-300mm APO DG macro..

my experience is limited, but i already managed to take several great shots with it, in all focal lenghts:
Since i'm not used to post here, i will post my samples in several replies.
first i will post several samples of 70mm.

well i'm in trouble, i do not know how to add an image to this thread..
when i'll figure it out, i'll update :)

here's the update :)

all images are straight of the camera
four samples of 70mm:

this image is: shot in P mode f/7.1; iso100; 1/400; no exposure compensation;

Image

Image

next image is: shot in aperture priority f/11; iso1250; 1/80

Image

Image

next image is: shot in aperture priority f/4; iso200; 1/80

Image

Image

next image is: shot in Shutter priority f/9; iso100; 1/1250

Image

Image

these are not the best shots, but there is no argument that this lens has any difficulties in 70mm focal lenght so, in the next reply i'll move on to greater focal lenghts were i usualy shoot with this lens.

the following images will be in various focal lengths, but not 70mm and not 300mm.

this image was taken: in P mode; focal lenght 108mm; f/5; iso100; 1/200;

Image

Image

next image was taken: P mode; focal lenght 260mm; f/7.1; iso100; 1/400;

Image

Image

to my judging all pics are razor sharp, crystal clear, with nice colors and many details.. i do not see any problems in the matter of lens operation..

to be continued.. with telephoto 300mm and later fabulous macros that this lens lets me to do..

here i'll post several pics of 300mm and one series of 70mm and 300mm from the same spot.

the following two images are taken in 300mm focal lenght P mode f/5.6; iso250; 1/160

Image

Image

the next image is taken in P mode f/5.6; iso500; 1/160

Image

Image

the next serries is, the first picture is taken at 70mm and the next at 300mm to see how the lens is zooming:

Image

Image

the distance to these buildings is approximately 8-10 kilometers.. about 5-6 miles

 Post subject: Macros
PostPosted: Mon Aug 11, 2008 1:28 pm 
Well, this lens lets me to do macro like pictures, while macro being 1:1 ratio, and this lens lets me to do 1:2 ratio.. so it's not quite macro, but as far as i experienced it it's quite enough to get dramatic results.. see for yourself.
more pictures on my flickr stream.

the following image was captured on P mode; focal lenght 300mm macro from about 90cm distance f/11; iso800; 1/200;

Image

Image

the next image was also captured in P mode; focal lenght 210mm macro; from a distance at about 1.5 meters; f/4.5; iso100; 1/200;

Image

Image

phew.. got tired :) hope this will be helpful..

Nice shots Mystic!! I'm thinking the one of the child and the trees could be a great black and white image. :!:

EDIT: Just tried it (hope you don't mind, I deleted the image afterwards) and I think it looks much better in B+W. However, you need to play around with the different colours when converting, not just let the program do it for you. Then she stands out really well.
