1 comments about Sigma 28-200mm f/3.5-5.6 DG IF Macro Aspherical Lens for Nikon SLR Cameras.

1. The Sigma 28-200mm zoom macro is an excellent lens for the typical portrait or landscape photo. I was a bit disappointed in the macro feature for a couple of reasons. While I realize that no telephoto lens can really take "macro" images, I was used to the 28-135mm Sigma macro that I have for my SLR film camera. A friend does have a 28-135mm for his Nikon digital SLR, so I was hoping to get one. That lens has a macro switch and a image ratio of 1:2. Unfortunately, Sigma no longer makes the 28-135mm lens, at least not for digital cameras. So I selected the 28-200mm macro with an image ratio of 1:3.8 and no macro switch. With my old 28-135, I could use one lens for just about all my photos; I will not be able to do that with the 28-200. Even with these exceptions, however, I do find the 28-200 lens to have very good optics and flexibility.

1. My copy of this lens gives good image quality, though it does have slight barrel distortion (things near the edge of the field of view bulge out very slightly). This is typical for this wide of a lens, and isn't noticeable unless viewing something with lots of straight lines near and parallel to the edge of the frame.
   I like the lens, but do make sure you really want a lens with a field of view THIS WIDE. It's nice for landscapes, but they will all have everything but the kitchen sink in each shot. You can't use this lens to isolate a particular feature of interest like you can with a standard or a telephoto lens.
   One feature nobody seems to pay much attention to on this lens is that it can focus very close! You can do a sort of wide-angle macro work with this lens, if the light is good.
   I recommend it as a relatively affordable alternative to the Canon or Tamron equivalents, if you are sure a 14mm lens is something you really want. I like mine, but occasionally have second thoughts about needing a lens this wide. Finally, I should mention that I use a digital SLR which only uses the central 2/3 of the lens. I've seen reports from others saying that edge distortion on this lens is unacceptable with a full-frame film camera.



2. do a little research and don't be fooled. Sigmas are generally a hit or miss thing for the lease quality. And wordt off if you travel and with the camera..seals are not at all reliable. Last but not least go ito a store and compare the drive noise on this unit to any other brand...very very noise...sorry i can not recommend them. Nikon, Tamron, Tokina...I personally prefer Nikon and Tokina...good luck



3. As another reviewer said earlier, sometimes the QA from Sigma is hit or miss. I have had the same experience in the past. The last 2 Sigmas I have tried have been fine (14 and 150 macro) My copy of this lens for Nikon is pretty nice (sharp, decent contrast if you keep light off the front element, fast accurate focus) on digital bodies. The HSM on mine is just as quiet as any of the AF-S Nikon lenses I have. I still prefer Nikon in general, but for the limited use I have for this lens, it has worked nicely.



4. The Sigma 14mm f2.8 is a great lens. It does a good job of keeping line straight. As others have stated you need to stop down (5.6 or higher) to keep sharp focus. That's the case with most very wide angle lenses. It is difficult to focus as others as said. That's just the nature of very wide angle lenses. If you shooting something up close then let the auto-focus do it for you. It you want to make certain it's in focus then measure (the old fashioned way). I've shot numerous projects with this lens and find to be major player in the very wide angle lens field. I've shot home exteriors, home interiors, art gallery interiors and even food with this lens.
   
   My only issue with this lens is that it does not handle blowout hot spots well. It tends to shift the color on the fringes of the hot spot to the yellow. You just need to be careful not blowout hot spots which why I gave 4 stars instead of 5 stars.



5. Just got this lens as a Christams gift, and I'm really impressed with it. It's a little soft at the edges wide open, but if you stop it down a bit, you get most of the corner sharpness back. It's also a little heavier than I'm used to, and I was suprized by how large it is. Nonetheless, it's a great lens for the landscapes I like shooting.

5 comments about Sigma 28-105mm f/2.8-4.0 Aspherical Lens for Konica Minolta SLR Cameras.

1. Don't overlook this lens. It does not have the longest zoom range available. But the F2.8 maximum aperature, the very serviceable 28-105mm range, the weight and size, the high quality of material and optics, and the price make this a pleasure to use and carry. If you want to carry only one lens, you need a longer range than this one has. But if you are going to carry two or more lenses, this one deserves to be in your bag.



2. I have always been a fan of Minolta bodies and Sigma lenses - they work great together (currently I have a Minolta Maxxum XTsi). This lens is certainly no exception. In fact, this one is the best lens I've had. I was so impressed with this lens, that I have all but stopped using any other lens. The aspherical capabilities allow me to get in real close to my subject and come out with a very clear photo.



3. This lens turned out to work far better than I expected. It really is a fine piece of work. I prefer to use it in manual focus mode because all the mechanical parts are smooth and precise, unlike most cheap AF zooms these days. The AF part is noticeably faster than Nikon's entry-level 50mm lens.



4. A friend of mine asked me to shoot her wedding (so she could save some money). I obliged, but panicked due to my lack of equipment.
   
   After much research on Amazon and various other sites, I decided to go with this lens. The first couple of times you work the zoom mechaism, there is some "stiffness" but that eventually fades, leaving a silky smooth feel. The zoom ring has a nice, high quality rubber coating for added control.
   
   Sizewise, it's fairly compact and light. I also own a Sigma 28mm F1.8 aspherical lens (no zoom) for the same camera and they are about the same size, length wise, and similar in weight. I found the overal auto-focus time to be a bit slow...but that's likely a byproduct of the older camera body rather than the lens.
   
   Overall, it was a great buy. The pictures came out beautifully! And the company that this product ships through turns out to be a fairly reputable company. Highly recommended.



5. I've been taking photos with an SLR for more than 20 years. Unfortunately, I've always been on a tight budget and could never afford the best lenses.
   
   I've owned this lens for about eight years now. It is THE lens that remains on my Nikon 99% of the time. I've used it in some gritty situations - in Iraq, Brazil, the California desert and all across the US as I traveled.
   
   I have to disagree with an earlier reviewer who stated you "need" another lens. I have a Nikon made zoom that goes past 200mm and I think I've used it three times at most. This Sigma is my work horse. Its wide angle is perfect for landscapes and close ups. The longer range is just what you need for portraits. I don't shoot sports or wildlife so anything beyond 105 is overkill for me.
   
   One of the great features of this lens is the 2.8 aperature at 28mm. You're forced to use 4.0 or smaller as you zoom, but this is still fine for portraits and a blurred background.
   
   If you're still using a 35mm and you're on a budget this is a great lens to have. It hasn't failed me yet in eight years.
