[Sigma 10-20 EX DC HSM] Lack of alternatives is one of the best super-wide for Nikon D-SLRs

From Axel Polt

this is still compact, quiet and ultimately convincing lens from Sigma.

Once at Nikon currently at 12 mm is final, this Sigma with a minimum focal length of 10 mm an important gap in Brennweiten-/Objektiv-Portfolio. The angle difference is much larger than the “small 2mm difference” of the focal length would suggest, according to small-equivalent to the difference between 15mm and 18mm focal length.

Haptics and use are very good. Uncorrected distortion and vignetting are noticeable, but easily manageable today. Simply the RAWs on DxO run; both vignetting and distortion are then disappeared and these results can be truly proud of: sharp, distortion-and vignettierungsfrei and small at 15 mm equivalent. With the purchase of key for me was (like any other lens) the availability of a correction module for this lens for my two D-SLR body. This lens I almost always there, it’s my Nikon 12-24 mm almost completely replaced.

Even with this wide angle is: f 5,6 is Einstellblende, should be worked with f 8 – f 11, on the need “free hand” to stop ASA 200 or go to the tripod (any recommendation for the D-SLRs in general … )

Conclusion: the absence of alternatives (especially with regard to correction modules for DxO) currently probably the best super-wide for Nikon D-SLRs.

[Sigma 10-20 EX DC HSM] It’s a permanent fixture on

[Sigma 10-20 EX DC HSM] It’s a permanent fixture on my D60

By C. Nation “chrisnation” (Bristol UK)

My favourite focal lengths on my 35mm film cameras used to be 28mm and 20mm. When I worked with John Claridge as his assistant, I often used to wish I could afford the 15mm Nikkor that he used so often.

Now this Sigma gives me 15 – 30mm [equiv] and I’m pleased as can be. If I was asked to spec a focal length range for a wide zoom, this is exactly it. The drawing you get from lenses from 30mm and wider gives the kind of interest I’m looking to produce in my pictures. It’s immediately made itself my default lens and max-wide tends to be my default focal length.

I’ve got a sklight filter in permanent residence and that is very frequently joined by a polariser. Polariser filters are by nature quite thick beasts so I do get a little vignetting at max wide and well stopped down but the merest touch of zoom in – usually only removing some of the area I’d already dialed in for a crop, but in any event, not usually enough change to ruin the shot – and the vignetteing is gone.

How Sigma do this for the price, I don’t know but it’s worth every penny. It seems chunkily well made. The images seem to be very high quality – tho I’m pretty new to digital photography so have no great fund of experience to draw on. I’d buy the equiv Nikkor every time if money was no object but Nikkors are totally beyond my budget.

But anyone with a Sigma’s worth of dosh to spend on a wide zoom, as opposed to the Nikon or Canon equiv, is going to be really pleased with buying this lens.

[Nikon 18-200mm] Surprisingly good image quality

Sunday, September 6th, 2009

From T-Freak

I use the lens on a Nikon D5000 and have rather a good compromise is expected. The more I’m surprised. The mapping services are truly excellent. The vignetting is minimized chromatic aberrations, I could not be ascertained. In the wide, there is slight distortion. However, I have the automatic Verzeichnungskorrektur in my camera, the excellent results and bring me in this respect after working at the computer saves. The image stabilizer does an excellent job! I have seen many pictures with 1 / 2 second exposure time is managed to an impeccable sharpness compared.

The problem here is often with the unwanted extension of the tube, I can not confirm. The setting provides a defined, relatively high resistance. Perhaps Nikon has somewhat changed. My lens I have with the kit D5000 acquired in early May 2009. Even an acquaintance of mine, of course this lens has noted that the adjustment for him much too easily respond.

Focus on something else. This is a 50 cm. This applies only to the wide-angle. In the maximum telephoto can be up to 20 cm Sharpen and realize good macros.

[Canon EF-S 10-22mm USM] Compact.

Sunday, August 30th, 2009

From iShopper

I have the only competitor not viewed, I must confess away front. Because as far as I know there are those slightly bulkier. An additional lens in larger dimensions and heavier weight, I wanted to I just do not pack in the bag, the back thanked me.

From the sharpness of her, I am also not so very pleased, I am of standard zoom a little more normally. Also the vignetting I can recognize almost all the shots. Do not want to miss the CA (chromatic aberration) at high contrast edges on the screen. The CAs and the vignetting can be a good way, the current DPP rausrechnen, same goes for distortion.

Positive feature is the lens when shooting against the sunlight, so are class effects erziehlen. Unfortunately, the lens is so much money that I swallowed my Geli later can buy (it is also recommended for 16-40) – the Canon would really start with in the package can do.

If the well-known problems of wide reporting relativised it is certainly an excellent lens. One should, however, the expectations of the image sharpness is not on the level of a 50mm lens hold, here comes the EF-S 10-22 is not ran.

Subjectively, the lens makes a relatively dark impression, I sometimes have the feeling it would take an unusually long exposure times of need.

If you like practical compact lens like this is certainly not wrong. Who sharpness is more important, the times should also watch the competition. Otherwise, I would like 10mm below the rum not miss, is not supported by all.
