#Sigma 18 35 1.8 pentax full#

Looking for a hella classy lens? Well, this is the one you’ll want to fall in love with over and over again. Sigma’s new 18-35mm f1.8 adheres to Sigma’s new Art lens philosophy in many ways–and one of those is in the looks. PerformanceĬomparable 35mm Focal Length: 28.8 – 56 mm Specs taken from the B&H Photo listing of the product. If you’re not a Canon user, spring for the Nikon D7100, Pentax K5 II, or Sony A77. Ergonomically speaking, however, we would fully recommend that this lens be mated to your Canon 7D instead. We chose this camera because of the fact that it currently has the latest sensor currently available during the time of this review.

Sure, everyone wants a full frame version.įor this review, we tested the Sigma 18-35mm f1.8 DC HSM with the Canon Rebel SL1. – APS-C only but that isn’t really a con. – Perhaps the absolute best concert photography lens that anyone can get their hands on Cons – The fact that you’ve got wide to normal focal length range at a constant f1.8 blows our minds Though the lens paid us a short visit (we only had it for five days) we fell in love with it.Īnd more importantly, we fell in love with its image quality. Previously, we had only seen f2 zooms being the fastest, but now there is a f1.8 zoom. But when Sigma announced their brand new 18-35mm f1.8 DC HSM lens for APS-C sensor DSLR cameras, we were shocked. Other APS-C users have posted information in that group also, do a search.Sigma’s latest 18-35mm f1.8 lens is the first zoom lens to their Art Collection: which is comprised of lenses typically associated with a very fast aperture. If you want to see what you are getting with the Sigma, I've uploaded some 100% crops into the Great Astro Lens test thread over in the Astrophotography group (post #64) The Great Astro Lens Test - Astrophotography. For nightscapes, the Sigma 18-35 is better, obviously faster, but also better corner star shapes at wider apertures. For general day use, I can't fault it, cracking! Much better than DA limited options. The centre is good from f2.8 so it is usable depending how critical the corners are for you. I have some star 100% crops of the corner and centre in my gallery (also linked from the lens review I posted) but to summarise with respect to nightscapes, there is some elongation of stars in the corner at 11 mm and the star shapes in the corners at the 18 mm end are not perfect so it needs to be stopped down. I currently have the 12-24 F/4 and the old 16-50 DA* and I'm looking for something more modern.Very happy with it. Thanks, are you happy with the 11-18 DA*? I am planning to get the sigma for night scape and astrophotography. Even with the 1.5 crop from the KP should be nice enough for astro. All those 16-50, 11-18 are f2.8 and you need to stop down them.I have the irix on my wishlist. For wide field I think there is nothing at all. They have *85mm f1.4 and *50mm f1.4 need to be stoped down to get good results, but then I don't see a reason to pay so much if they starting to be good from f2.8. I would be happy to spend my money for something good for astro(fast and no aberrations) from Pentax.

I'm using Irix 15mm f2.4 and Rokinon 24mm f1.4 and Sigma 18-35, but on FF it usable from 24mm(very small crop needed). All those 16-50, 11-18 are f2.8 and you need to stop down them.

I'm waiting for clear sky without clouds and moon. Now I'm going to buy again 21mm f1.4 from Irix, with 1st copy I had a bed luck.

Very flat field, nice star shapes, only CA is makeing a bit of problem and slow f-number. I also own Takumar 200mm F4 in M42 mount. Rokinon 24mmf1.4 usable from f2.5, probably not best copy. Not the fastest but fast enough and on FF it's wide, maybe even too wide Irix 15mmf2.4 is really good lens for astro. I currently have the 12-24 F/4 and the old 16-50 DA* and I'm looking for something more modern. I was eyeing the f/1.8 for the extra stop of light.

Yes, the list of modern glass is limited, which lens are you currently using for astrophotography? I have the 12-24 mm f/4 and the old 16-50 SMD lens.
