Both Lenses were adequately sharp, but I would have to agree with others who have commented, I really think that the 50-500 is the slightly sharper of the two. Teamed with my D7000, Color and contrast has also been very good.
After taking this lens to Alaska and shooting nearly 5,000 shots with it... I am truly impressed. Build quality is impressive & this lens has a solid feel in your hands. Most of my shots were free-hand of Eagles, Bears, and such... Only a few times was I disappointed in a shot, and they were ALL in very dark situations. A tribute to their OS, and a knowledge of what you can accomplish with it.
This lens IS my "walk around lens" I do most of my shooting outdoors. Birds, mammals, butterflies, or whatever catches my eye. I have also used this lens quite a bit with a 12mm extension ring for macro shots. Setting my f-stop to 14-20, I am able to get GOOD quality macro shots using this lens/extension tube combination.
I am truly a fan of the versatility this lens delivers. Literally from the moment I stepped off of the plane in Alaska, I began taking pictures of Windflowers & wild Foxglove. From there I backed off the zoom and took scenery pictures, and EVERYTHING in between. Sure a f1.8 50mm may have taken better scenery shots, but if you are like me, I HATE CHANGING LENSES, and the shots that I did get were completely acceptable. I am amazed at the sharpness Sigma has been able to squeeze out of this lens, at 50mm, or zoomed out to 500mm and everywhere in-between.
Focusing was in my opinion, as fast as any lens I have tried, NO i don't own a f1.8 nikkor to compare to. However, I took hundreds of pictures, from Whales to Eagles, where I had tenths of a second to get the picture... very seldom (if ever) did it fail.
This lens is heavy. The tripod mount/carry handle, makes carrying it around managable. If you are 5' tall and weigh 100lbs, you may not be able to lug this lens around all day. But with a little weight training and excersise... yes if I had to, I would !!!
If you want to get the most Reach and versatility out of your DSLR without spending thousands & thousands of dollars for prime lenses, in my opinion this 50-500mm lens is an excellent choice.
Updated.... Unknown to me before my trip, My D7000 lens/camera focus can be fine tuned. After fine tuning to -6 in my camera, the sharpness of this lens has been improved even more. For those who think -6 might be extreme.... my 18-105 nikon lens had to be fine-tuned to a value of -5. If your camera has a fine tune mode, I urge you to utilize it. This slight tweak improved image sharpness that last little nnnnnnth to crazy sharp.
I primarily shoot primes and wasn't quite expecting much sharpness from this lens, but it is sharp! Especially considering it's a zoom, and even more - a long telephoto zoom on a budget!
The build quality is superb, the finishing is very nice and the entire lens feels very solid. The stabilization system is simply amazing - IMHO it's far superior to Sony's in-body stabilization. Shooting handheld with 1/200s exposure @ 500mm - no problem at all. Also love the versatility of the lens - it goes from "standard" 50 mm to 500 + a decent macro as a bonus. It could be a great all-in-one walk-around lens if was 10 times smaller and 20 times lighter :)
I was wondering how I suppose to carry this lens on a tiny A6000 body, but found the lens strap in the box - very handy! The lens case is also very nice. Now I'm a Sigma fan.
One last note for the buyers - the lens fully extended with the FF hood attached on top of the APS-C hood with a barely noticeable e-mount camera body looks like a short bazooka, so be prepared to "answer some questions" ;)
So far in my tests it has been very sharp and operates smoothly. I will add a few test shots I made just after opening the box. BTW I read the information sheet and learned a few thing I had not known when renting it. For instance they say to turn off the image stabilization before removing the lens as it may create problems later.
First image, close up, un-cropped but re-sized from med RAW capture (10 megapixels) using a Canon 7D. I did a mild edit in LR for contrast. 500mm f/6.3 iso 400 shutter speed 1/200 (yes OS was on) hand held.
Second image same place and time just zoomed out at 50mm f/5.6, SS 1/200, iso 200
My one complaint: The lock switch that is used to keep the lens from extending. I have issues with it being difficult to unlock if the lens has any downward pressure . So if it is faced toward the ground when you try to unlock it the lock will catch and you have to tilt the lens upwards to unlock.
Side note it is HEAVY (which is to be expected). Walking with this around your neck or shoulder for 4-5 hours along with a pack is a workout. But what can I say, you get a lens like this and what can you really expect. Especially for the fact that you can still get great picts without requiring a tripod.
I ABSOLUTELY would make this purchase again!
Update: Next month four years since I purchased this lens. It continues to take excellent photos, even after enduring two years of east African roughness and a month of backpacking around India. It remains a great purchase.
