Reviews and Problems with Sigma 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM
Showing 1-9 of 9
Fishy. Very, very fishy!
9 May 2013
Summary: A nice, ultra wide angle lens. The HSM focus drive is fast and quiet. One great added feature is the adapter for the lens cap. It has 72mm threads, so unlike most ultra wide angle lenses this lens can be fitted with a protective filter, which is very important for valuable lens optics. Granted the added filter causes some vignetting, but with the circular fisheye nature of this lens the small added amount of vignetting is not really an issue.
Excerpt: Focusing can be done on objects that are only mm away. This leads to my biggest concern when using this lens: the danger of hitting the object that i'm focusing on, resulting in a scratched front optic.<br /><br />So far, I have had a lot of fun photographing every day items resulting in unusual results. <br />The main draw back to this lens, in my opinion, is that it is very pricey for what could be considered a "novelty" lens.
Pros: A really wide angle lens, Easy To Use
Cons: Can't use a filter, Easy to bump optics, See a barrel in photos
Summary: This product is great except cost. If you don't mind spending around $900 then this lense is for you!!!! If you are budget minded you could get a manual lense far cheaper that produces the same great pics. The only reason for 4 stars is cost everything else is wonderful.
Summary: I picked this one out for my Sony Alpha 77 from all the other options, because this one has autofocus. I take a lot of self portraits and I needed autofocus for that purpose. It is exactly what I expected, works well in low light, sufficiently sharp, and fun to use. I just think that price tag is a bit high, when you can get a manual focus one for $250.
Summary: Combined with Nodal Ninja rotating tripod heads, I'm using this lens to produce equirectangular 360deg x 180deg panoramas. Six shots in 60deg increments work perfectly when stitched with Hugin or AutoPano. Limited depth of field is a problem --- I find that typically I have to operate the lens at f/11 or f/16 to get decent full-frame-in-focus results, which necessitates shutter times of > 0.5s indoors, so it's only really useful for static scenes.
Summary: I've wanted a "comedy" lens for a while and also wanted to continue with VR pano shots without having to shoot 100 plus pics for hours of stitching so I plumped for this little lens. On unpacking, i have to say that for my first Sigma, I was pleasantly surprised. Solid feel, rugged exterior and functional. Minor gripe is that with Canon fit, the AF/MF switch is a bit poorly placed.
Summary: You probably need more money than sense, or be a scientist on a grant to buy this. I am the former. Used on a D300 it gives a staggering globular image that you need to zoom in on with your preferred software to make a useable rectangular image.
Pros: Very unusual
Cons: should i have got the full frame nikon 10.5?
Tolles Einsteiger Fisheye. allerdings kleiner Nachteil.

Summary: Vorab: Ich habe dieses Objektiv gebraucht in der Bucht bekommen (unter 400€) Das 4,5mm Fisheye zeichnet meiner Meinung nach sehr scharf bis zum Bildrand, wo allerdings der Nachteil begraben liegt. das Objektiv nimmt sein eigenes Inneres mit auf und erzeugt bei starkem Lichteinfall Regenbögen. Positiv finde ich, dass es bis auf die Staubkörnchen auf der Frontlinse fokusieren kann und das der HSM Antrieb sehr flink arbeitet.
