PostNew Sigma 85mm lens is a KEEPER!

Last night was my first chance to get the new Siggy out for a test drive.

Shooting in a somewhat brightly-lit gym, I expected to have to resort to ISO 1000 or so in order to keep my shutter speed up around 1/400 of a second. Boy was I wrong! Either the gym has great lighting, or I am just not used to such a fine performing lens/body combo as I had last night.

I was able to get ISO 400, f:1.4 and 1/500s exposures (set on manual) all night long. Sure there were some that were a bit dark, especially those shot under the basket or in the shadows of another player, but by and large, it was not too bad as far as exposure was concerned.

I have found that with the D300, anything over ISO 800 requires you to nail the focus & exposure, or else (lack of) sharpness and excessive noise take over when trying to fix them in Post-Processing (PP). Last night was a breeze, although the White Balance (WB) was a bit warm out of the D300, but at least it was consistemtly warm when set to auto. The D200 WB was all over the place as usual. I have yet to find a good manual setting for these particular lights...

Anyway I used the JV game that started at 6:PM to test the combo and dial in the exposure. I started at ISO 800 and f:2.8 or so but quickly realized I could cut that back quite a bit and shoot ISO 400 to preserve a lot of the detail and dynamic range. Here is a shot ISO 800, f:2.5 1/400s:



All of these shots had very minimal PP work, generally just some slight sharpening and exposure adjustment.

Here are a couple more with the same exposure settings:




See how just a slight push or block can make all the difference in the world as far as 'perceived' action is concerned? This is why I shoot at 8 Frames-Per-Second (FPS), in order to possibly capture that EXACT moment where a facial expression or body pose will make the difference between a ho-hum shot and one that belongs in Sports Illustrated.

After the Varsity game started around 8:PM or so I thought I had things pretty much dialed-in. Here is a shot at ISO 500 f:2.0 1/400s:



As you can see, generally 1/400 is fast enough to freeze most action, and it is also fast enough to allow the camera to use the max FPS rate it will allow. 1/400 is fast enough so you don't 'need' VR, unless you are hand-holding a huge lens and have Parkinson's disease.

By the 2nd quarter I had settled in on ISO 400 f:1.4 1/500s:



I don't know how thin the DOF was at this distance (use one of Pats' handy calculator links to figure it out for yourself...), the actual distance reported said 'unknown', but I would guess it was 30-40 feet. I wonder if it reports the distance with Nikon lenses?

Anyway, I think with a little more practice I will have gotten used to this beast, it balances well but is still heavy with a camera that has a grip with 8-AA batteries inside. I use the hood for the FX option, the DX hood has an additional 2-inch adapter that adds a lot of unnecessary length to the combination. I just need to shield the front of the lens from the overhead lights, but it serves very well if an errant ball comes my way.

The focus is incredibly fast and accurate, easily as fast as the 17-55/2.8 DX, which is known to be one of Nikons fastest-focusing lenses. I will be experimenting with the different focus modes later this week, after I am sure I can get the exposure dialed in properly. More about this new Siggy later!

Sigma does make some of the better lenses in the world today. Would not have said that ten years ago. I have newer sigma kit lenses that are very good!

I have never shot sports, but I would think it is very challenging. I would like to try it someday.

Thanks for a great review of the siggy 85. It's on my wish list.

There's also an app for hyperfocal length for iPhone (don't know the name of that one)
and one for blackberry "depth of field calculator". You type in your camera's format
and lens focal length.
It also has the option for feet and meters.

For me, shooting sports is easy. I have great access to some wonderful athletes.
That is half the problem... then you DO need some good gear, and great timing.

It is the 'other' aspects of photography that are difficult to me, stuff like shooting weddings...

Very nice Micky.

Seems it is often about practice. I have shot 3 weddings as an amateur but everyone was happy with the results. The last one was shot with a Canon G5 P&S so was a while ago now.

Big thumbs up on the rundown.

Thanks guys. I just wanted to give a bit of real-world info here.

Too many times you only hear about the problems with camera gear, when something works well, people are too busy using it to take the time to rave about it. Since I have heard a lot about Sigma problems in the past I needed to vent a little bit and show off some of the great gear they are making.

Personally I think Sigma glass is just as good as Nikon, at half the price. Now I run the risk of pissing off all the Nikon cork-sniffers, but I really don't care, I am not a pro and nobody gives me gear to use so I don't have any connection to anyone expecting my endorsement.

Who would want my endorsement anyway? (nobody!)

Certainly gear has gotten so good as of late that it is starting to outperform even the best photographers. I know the stuff I hav is far better than I deserve. I will never reach the potential set by the manufacturers, so I can only hope to approach using their gear to the fullest extent.

As the 85 is my basketball lens, I will try to find other uses for it, but I cannot imagine using it for anything else except a close portrait or two now and then. It is about the equivalent of a 135mm lens (approx) on an FX body, and I never really got comfortable in that range for anything except basketball. Oh well.

Anyway, thanks for reading, I hope you can all gain a little insight into this particular lens from my trial and error use of it...

Sigma is my second favorite lens maker, very close to my favorite NIKKOR!

Sigma is the only 3rd party lens I own. I have been happy with the two I have so far.
