Reviews and Problems with Sigma APO 135-400mm F4.5-5.6 DG
Showing 1-10 of 34
3 April 2010
Conclusion: may be good as a cheap start up, I got some sharp images of the moon, until I removed the UV filter, F/14 and in a tripod, (UV filters will make images a bit softer) Images comes out with a brownish color, lens creep like s..
Pros: got some sharp images of the moon in a tripod at F/14 no UV filter, I can't think of any other, oh! the foam paded lens case, better then canon's and nikon
Cons: super slow and noise focus, hunts, lens creaps, fits looose in Nikon D90 body,
Summary: 1. This lens can be a great lens, or a headache. Somehow, and probably also because of its weight, this lens can not be easily handheld, and can not produce a reasonable sharp image if not on a reasonable high shutterspeed - nothing below 1/250 at all... 2.
Summary: Bought this from Amazon at the same time we bought the Sigma 10-20 super wide and the Canon 100MM Macro. Those two lenses are great, this one is a complete dog. Unfortunately, we have been so busy with the other two only recently have we had the need to use this one.
Conclusion: I highly recommend this lens for beginners. My problem with it is that when trying to take photos (of wildlife in my case) from a distance they turn out very soft and noisy. From a moderate distance a small aperture of 8-14 is needed for decent quality.
Pros: Great price, excellent for beginners, tripod collar, good quality at a close distance.
Cons: Horrible autofocus (noisy, hunts, and slow), lens creep; bad, soft quality when photos are taken from a distance. Not sharp.
Conclusion: Inconsistant is what this lens is. I have given it a workout in different conditions, settings, hand held, tripod and I would say that for every 100 shots I would get 1 that I am just happy with. It is a fair weather lens to say the least. If you can't get 1/1000th then forget it.
Pros: Price, build quality, tripod collar
Cons: Shocking lens creep, slow AF, soft images, noise (ISO)
Conclusion: I notice that there is a wide dicotomy between the positive reviews and the negative ones. It's difficult to see what people are expecting. Sigma's QA has always been in question. I also wonder, therefore, if that it's partly responsible for some people saying that this lens is sharp wide open, and...
Conclusion: Pre-purchase reasons for buying this lens: · It sat well priced with my healthy but balanced hobby budget. · It cast a full frame image circle (making it more future proof and able to be shared with my film based camera).
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.
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.
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.
