The Saga of the Sigma 120-300 f/2.8 OS Sport

The Saga of the Sigma 120-300 f/2.8 OS Sport

A Canon Rumors reader “JerseyShooter” has been working with Sigma to improve the performance with Canon’s APS-H flagship cameras, the EOS-1D Mark III & EOS-1D Mark IV.

Back in October of 2013, JerseyShooter started a blog documenting the issues he was having with the lens on a blog. He worked directly with Sigma and it looks like it has paid off with the firmware that was released yesterday to improve the performance with both of the mentioned cameras.

There have been other issues with the lens that he is documenting on the blog as well.

For the record, JerseyShooter is an employed professional photographer.

Upcoming Lens Reviews of Sigma & Zeiss Glass

Upcoming Lens Reviews of Sigma & Zeiss Glass

I have finally purchased the Zeiss Distagon T* 15mm f/2.8 and will be putting it through paces on a two week trip to Namibia beginning on April 6. For filters, I’ll be using the Sigma 95mm DG Circular Polarizer, as well as large Singh-Ray grads when needed.

My immediate first impressions are quite good, amazing build quality, great zoom ring  and the silly test shots looks terrific. I’ll be shooting exclusively with the EOS 6D on this trip.

Justin has received the Sigma 120-300 f/2.8 DG OS for review and he’ll be putting it through the paces with the EOS-1D X. He’s already shocked at the size and weight of the lens. No, it’s not a “hand holding” lens for most people. The first 2 negatives you can give the lens is the heavy and unnecessary metal lens hood and the equally enormous tripod foot. Third party accessory makers could surely knock a pound off the lens replacing both parts with lighter weight materials.

Optically and AF wise the lens is very good with initial test shots, Justin has the USB dock and will also put that through its paces.

Both reviews should be online some time in April, though I’ll be posting images from the Zeiss 15mm as the trip progresses.

The New Sigma 120-300mm f/2.8 DG OS HSM Reviewed

The New Sigma 120-300mm f/2.8 DG OS HSM Reviewed

From The-Digital-Picture
Bryan over at TDP has completed his review of the new Sigma 120-300mm f/2.8 DG OS HSM lens.

Bryan, just like a friend of mine that is sponsored by Sigma in Canada, was pleasantly surprised about how much they like the lens. I keep hearing the build quality, optical quality and focal range are very useful on a day-to-day basis.

From Bryan
“It is hard not to like a great looking lens with a 120-300mm focal length range in a non-extending, solidly built body that also feels great – and delivers image quality that leaves most other zoom lenses wanting even at this lens’ wide max f/2.8 aperture. I like the direction Sigma has been going with their recent lenses and I think they have another hit with the Sigma 120-300mm f/2.8 DG OS HSM Lens.”
