Reviews and Problems with Sigma APO 135-400mm F4.5-5.6 DG
Showing 1-10 of 13
8 August 2007
Conclusion: This lens does nothing wrong. Image quality is good and consistent thru out the zoom range apart from getting a little bit soft over 350mm. Images wide open at 400mm are still very usable for a enthusiast like myself. I haven't noticed the IQ getting any better stopping down. I did try this lens in store before buying and i'm pretty sure I have a good copy optically anyway. CA is well controlled needing pixel peeping to detect.
Pros: Image quality, Build quality, compact size and weight, Included lens hood, tripod ring and carry case.
Cons: Lens creep, el cheapo sigma lens caps (both ends), mf/af switch. Focus ring spin when focusing.
Conclusion: OK the weight is an issue but lets be real here...it is a 400mm f5.6 lens. It weighs about the same as the Sigma 70-200mm f2.8 and it's physical size is comparable. But the build isn't quite comparable, the base of the lens is made from metal (which is why it's so heavy) and feels cool to the touch. The weight drops a lot if you remove the tripod collar and it's the same collar that the 70-200mm f2.8 uses. So I only take one collar is I take both lenses.
Pros: The price and focal range. Hood and tripod ring and lens case included. I like the 77mm filter size. Excellent contrast and good enough IQ.
Cons: The AF is a joke really. It's noisy, crass and slow. The focus ring rotates when it focusses too. Not HSM or EX. It's very heavy too. A very stiff zoom ring. The lens REALLY extends in length at 400mm.
Conclusion: If you are looking for something better than your run of the mill 70-300/4-5.6 zooms, but cant afford a $1000+ lens then this is a good balance... It does extend a lot when zoomed, but the barrel is solid and has no freeplay... Mine has very little if any zoom creep (very stiff zoom ring).. On my *ist DS it does tend to backfocus a little when wide open and at its wider end (like some other Sigma zooms).
Pros: Very solid build for the price range, rather sharp when used on a monopod, fairly cheap yet not cheap and plastic feeling...
Cons: Backfocus at less than 250mm when near wide (like many Sigma lenses..
Conclusion: I have canon d 20. I have taken a lot of pictures with that lens. The proce of this Sigma lens is very good and I wolud recomend that lens for people who don't like spend a lot of money and who want to have a sharp lens for small money
Conclusion: This has been a great lens for me. It is a little heavy and long… you must use it with a tripod or monopod… the zoom does creep… BUT it is SHARP. I’m pleased with image quality on images shot wide open and at all focal lengths! It is sharper stopped down but it's sharp enough used wide open. This lens is a true APO so say goodbye to purple fringing (CA) on high contrast areas. It isn’t the “best” 400mm zoom money can buy but IMO it is the best for under $450 US.
Pros: Sharp, great color, good build, good AF and a great price.
Conclusion: I own this lens now for a couple of months. In common I am pleased about the results of this lens. Especially when you use it stopped down to F11 the results are good! No Chromatic Aberration and well sharp. The negative site of that is that you can’t really use it handheld. Because then you will need to use it wide open, and then the results are disappointing! The images are soft as a baby bud! So when used with a tripod or beanbag, you get a lot of fun for the money!
Pros: Solid build, easy to handle, good images when used stop down.
Conclusion: I will say I am somewhat pleased with the performance of this lens. I found I pretty much only used it at the 400 mm setting and got very good results stopped down to f6.7. Great lens when you have the light to work with. Reccommended for someone on a budget.
Pros: Pretty sharp all the way to 400mm....stopped down to 6.7
Conclusion: The zoom range is great particularly for DSLR owners as myself, you end up with a 202mm to 600mm that compliments well any 80mm to 200mm zoom or similar. I have read that image quality is very good up to 300mm, from then on it's a bit soft, but my lens does not show this problem. I NEVER use it if it's not sitting on my Bogen 3036. Actually, I never shoot anything and regardless of lens if not on a tripod.
Pros: Great zoom range and macro capabilities. Excelent glass, very sharp.
Summary: Questo obiettivo può essere una grande lente, o un gran mal di testa. A causa del suo peso, questo obiettivo non può essere facilmente trasportabile, e non può produrre un'immagine ragionevolmente nitida, se non con una velocità dell'otturatore ragionevolmente alta - non inferiore a 1/250 Bloccato su un treppiede solido (intendo un treppiede solido come una roccia) produrrà immagini nitide e con un bel colore vivace.
Summary: da mein altes Sigma zoom 170-500mm bei den vielen Einsätzen, die das gute Stück hervorragend geleistet hat, langsam aus dem Leim geht. und es hat, da ich freier Pressefotograf bin, wirklich viel mitgemacht, habe ich mich für ein neues sigma Objektiv entschieden. Diemal 135-400. Nicht ganz so lang.
