First I attached to the USB dock to find out distances and then I ran the test at these distances. I did not test infinity because I will never shoot at infinity. After testing the only setting that needed a little adjustment was at 2 meters of -5 on all FLs. All other distances/FLs are spot on. Lens fit and finish is in line with other latest Art lenses. It focuses extremely fast from either direction. Sharpness is OMG. Here is a test taken in RAW processed with default no sharpening added. This is at F1.8. The only sharpness like this I have seen from stop down lenses to at least one stop. I really don't care about bokeh much. The only negatives I see is that focus ring is upfront so I have to support the lens by the hood otherwise my hand wants to change focus. The second negative is the collar. I don't care that is non removable but it should have been longer with more holes. Or it should have been made like on 70-200mm Sport with replaceable foot. -- hide signature -- If I don't respond to your post after you responded to my post with NEGATIVE remarks that means you are on my Ignore list.

SushiEater wrote: This is the one lens that sits in my wish list that I cannot seem to decide which side of the fence I want to be on about it. I have moved it to my cart at least twice, then taken it back out. It's driving me crazy. I have 85 1.8 and a 50 1.8 primes (both Nikon) and the Sigma 18-35 1.8 that I use on my two 7500s for weddings. Both of my primes are very sharp and once I went through the incredibly laborious process of the USB dock with my 18-35, It is a fantastic lens. I do not seem to experience the issues with the 18-35 that others have concerning missed focus in the outer focus points. My thoughts on getting the 50-100 is concerning wedding ceremonies. I keep the 18-35 on one body and the way my belt is set up, I can quick change between the 50 and 85 on the other body. It's not terrible and I am pretty quick with it, but I cant help but wonder if it would be easier with just running an 18-35 and 50-100 on two bodies for the ceremony. The reviews (and I have read probably every one there is, LOL) on the 50-100 really seems 50/50 to me. They either like it or they hate it. The one common thing I have seen in reviews is that the 50-100 seems to have issues with the outer focus points and missing focus. Some reviewers say they cannot seem to figure out the reason for it either. "With the outer focus points, there is no correlation with missed focus to conditions shooting. It will focus tack sharp for a good period of time, then out of no where, you will experience several missed shots." That is a common statement about this lens. Have you experienced this with your lens? I would love to pull the trigger on this baby. I just think a 70-200 is going to be a bit much on a crop body at a wedding for my style of shooting. But, the really mixed reviews on the 50-100 have me just climbing the walls with this decision.

Few were out of focus probably because I touched the focus ring because in the same sequence there were sharp ones too. I caught myself touching the ring several times. All shots were focused with the second point on the right (second below top in portrait) and the 99% were in perfect focus. -- hide signature -- If I don't respond to your post after you responded to my post with NEGATIVE remarks that means you are on my Ignore list.

Have this lens myself and its something else image quality wise, have had focus issues, but tune it with the dock and works well overall with a d7200, I found the focus points around the center to be fine but if you go for the edges its going to back/front focused, so focus and recompose has been the order of the day. BUT ive just upgraded to the Z6 and with that focus system it is hitting everytime no problem (Its really showing just how stunning this lens is to be honest) So i would imagine the same would be true on the Z50, which makes this the must have lens for any dx shooter thinking of getting a z50 OP (unknown member) • Forum Pro • Posts: 11,356 Re: Sigma 50-100mm F1.8 DC HSM Art quick review..

Yes, I used dock as I mentioned in the review because at 2m it was back focusing a little on all focal lengths. -5 cured the problem. As far as IQ from the short to long end please explain. The way I shoot and there I shoot I doubt very much if I notice anything unless someone point that out. -- hide signature -- If I don't respond to your post after you responded to my post with NEGATIVE remarks that means you are on my Ignore list.

Using OEM lenses sometimes covers it up. When someone says they have lots of focus problems I look first to whether they have a professional or consumer body. I don't think you should get the 50-100. It is a heavy item which is best for dual system users of DX & FX. On FX you can use it as a 100mm f1.8 prime. You may come to resent the weight. An 18-35 & 85 kit sounds fine. Only using the 50-100 on DX is like having a short 75-150 f2.8 lens on FX without stabilisation for no benefit in weight. The corners are just a bit better.

The lens is still 50-100 F1.8 not F2.8 even on DX. And with the crop factor it acts as 75-150mm F1.8 so really no need for stabilization as much as you think. This lens was designed for a low light shooting and if Sigma added OS it would be even heavier and cost a lot more. -- hide signature -- If I don't respond to your post after you responded to my post with NEGATIVE remarks that means you are on my Ignore list. Photography Director for Whedonopolis.com Re: Sigma 50-100mm F1.8 DC HSM Art quick review.. 1 Sushieater is doing a disservice to the uninitiated by dismissing the standard photographic concept of Equivalence. I write not for the benefit of that user but only to newbies - do an internet search for it. A 100mm f1.8 lens on DX gives a field of view and depth of field like a 150mm f2.8 lens on FX. This is not a coincidence but completely mathematic and scientific. It's to do with the reduced sensor size. Readers should realise Sushieater is out there on his own by denying the photographic concept of equivalence. Any newbie can prove equivalence to themselves by picking up a 25mm on an Olympus in the camera shop and seeing what the viewfinder shows has little in common with a 24mm lens on "full frame" cameras. They'll only see half the scene, because the sensor is only half as wide. And the problems for Sushieater's arguments go on and on... Let’s get the last fact right: at the end of the day, it all boils down to what works for you. If you only care about image quality, larger will always be better. It will come with weight and bulk, but it will give you the largest prints, the best image quality, paper-thin DoF, beautiful subject isolation, etc. OP (unknown member) • Forum Pro • Posts: 11,356 Re: Sigma 50-100mm F1.8 DC HSM Art quick review.. 2 threw the lens wrote: Sushieater is doing a disservice to the uninitiated by dismissing the standard photographic concept of Equivalence.

The later only changes if you change your camera-to-subject distance in order to adjust for the same field of wiew between DX and FX. If you stay at the same distance to your subject, there is no change of DOF whatsoever, with the only difference being that the crop factor magnifies everything, including the out of focus areas, if you compare DX with FX photos at the same size on your screen. - The aperture, and therefore the ability of gathering light doesn't change, no matter what sensor size you put behind it. People talking about equivalence should realize that a crop-sensor does nothing else than that: cropping. Everyting else stays the same from an optical point of view. Maybe you missed out on some important parts when you were a "newbie", and should go over the books again.

Hi, I am considering this lens but wondering how it might perform for indoor poorly lit basketball. I'm not a professional by any means and I currently have a 7dII, paired to the older sigma 70-200 2.8 however I find in our home gyms lighting is so bad I struggle to get to the right shutter speeds to correctly stop the action while having to shoot very high ISO. I also find many shots out of focus with the sigma 70-200 so I'm wondering if I'm better off to trade that in for a 70-200 Canon II or III for better AF or is that difference not worth while and grab this 50-100 1.8? Will the difference getting to 1.8 help more than upgrading the 70-200 to a canon lens for this application? I also worry that if I get this 50-100 on my crop and it works well, then the 70-200 will not really have any use further? I also find many times that my shots especially under the basket where I like to roam, the 24-70 just needed a bit more reach but the 70-200 was a little to much reach. Many of my shots actually end up in the 50-100 range as I look at them afterwards. I also have a tamron 24-70 that i use for wider type shots and I usually just swap at half time as my only other body is an old t3 that cannot really handle these 2.8 lenses very well or low light situations , at least compared to the 7dII so I just do half and half.. perhaps the 50-100 can just handle the entire game without having to swap. Thanks in advance for any suggestions. the only other idea which I don't want to do and it's more expensive is to somehow sell the 7dII and go with a FF and just keep the 70-200 on a FF like the 5d III or something somewhat affordable... isn't the same result accomplished by adding a 50-100 on a crop at 1.8?
