Sigma 150-600mm brothers

Sigma announced a 150-600mm f/5-6.3 DG OS HSM Contemporary (above on the right) and a higher-end 150-600mm f/5-6.3 DG OS HSM Sports (introduced here a few days ago). We now know that focal length and aperture are not the only parameters when it comes to deciding in which category a lens should go.

So let’s review the common features and differences.

    I’m still waiting for 24-70mm f/2.0

  • animalsbybarry

    Admin…can you publish side by side mtf charts on these 2 lenses as soon as they are available…
    Unfortunately as a Sony user I must choose between the contemporar version or buy another brand of camera to use the better one…I am extremely anxious to see any info that allows me to compare optical performance of the two lenses.

    • Florent – SigmaRumors

      Sure, I will.

      • animalsbybarry

        Thanx…it would also be usefull to include the Tamron charts for comparison.

  • Pittsburgh Kid

    From Sigma’s site, the Sports version is USB dock compatible, whilst no mention is made for the Contemporary model.

    sigma would do well to publish MTF curves for both, or forward a pair to DXOMark, for consumers to get an idea of relative performance. Introducing identical focal lengths without more clarification causes consumer confusion. (Alliteration apology)

    Right now, the Sports model is fetching, but only if optical performance is superior.

  • EarlFargis

    Silly me, expected a single lens. I await details to answer 2 important questions. Will Sigma eventually offer the Sports in a Sony mount? Will the Contemporary offer IQ to match the mediocre Tamron while the Sports really boosts the IQ? Even at the stiffer $2k pretty much going double it’s so cheap for this range not expecting much.

    • SimenO

      I’m curious about the weight. 2,8 kg is a beast. Even Tamrons 1,95 kg is pushing the limits for me. If Sigma can match Tamrons quality at a lower weight it could be what i’m waiting for.

      Or maby they will listen to my suggestion and make a lightweight 500mm f/4 mirror lens with HSM, OS and back end filter wheel sometime in the future. A selection of apodizing filters to smooth the bokeh and limit light like a normal lens would limit light with ajustable aperture.

      • Mike

        Smoothing the bokeh doesn’t really work when you still have that big gaping hole in each circle 😀

        • SimenO

          Actually it does help even if it can’t compete with a refractive 500/4 lens. It makes the bokeh less stressfull, especially with patterned out of focus areas as leafs, waves, grass.

      • animalsbybarry

        My suggestion for a mirror lens is an off axis CAT
        Similar to a satelite dish the primary mirror would be aspherical and the secondary mirror wold be off center and flat.
        This would eliminate the hole in the middle allowing better DOF and a diaphram.

        • SimenO

          I would like to see tests of that. The concept are like yolo telescopes, and they produce horrible comatic aberration (Points look like comets). I’m not shure wich bokeh is the most problematic.

          • animalsbybarry

            Mirrors do not produce any chromatic abberations however they are prone to distrtion..in the case of the Yolo yelescope..astigmatism.
            The Yolo consists of 2 concave mirrors mounted off axis from each other so the secondary mirror does not block the light from reaching the primary and reflects it to a location alongside the primary.
            The solution that has been suggested for this distortion is to grind the secondary mirror into a torroidal shape. It was suggested that this be done by attaching a warping harness to during the grinding process.An alternative correction method that was suggested was a glss element.
            With modern technology a more effective manufacturing process can probably be desighned and computer aided desighning can probably far surpass what was possible in the 1960s as far as optical quality is concerned.

          • SimenO

            Not chromatic (color) aberration, but comatic (coma) aberration. The of axis design produces horrible coma.

            https://en.wikipedia.org/wiki/Coma_%28optics%29

            Mirrors do not produce _chromatic_ aberrations, but mirrors are rearly used without optical lenses in the back part of the telescope, wich _are_ proned to chromatic aberations.

            A real mirror lens construction would produce both aberrations and others, but there is tricks to reduce some of them. The of axis secondary mirror is trading ring bokeh for coma. I’m not shure wich one are the worst.

          • animalsbybarry

            Another approach suitable for longer focal lengths might be a Schiefs Kutter like desighn utilizin 2 simple spherical mirrors much like a schmidt cossagrain or modern cat lens.
            By locating the concave primary and convex secondary at the appropraite distances the astimatisms will almost cancel each other out..and possibly additional glass elements similar to the field correction built int current f6.3 adapters cold eliminate the remaining distortion.

          • SimenO

            Interessting compensation technics. I didn’t know about those. I read briefly about it here:

            http://www.schiefs.com/schiefs02e.html

            I hope Sigma would introduce somthing like this aimed for photography.

          • animalsbybarry

            According to your link the torroidal secondary perfectly compensates for the coma/astigmatism introduced by the off axis spherical primary…therefore the Yolo desighn might indeed be an excellent model for designing a reflex lens for cameras.
            Your suggestion of using a Yolo desighn is one sigma should consider.
            When I suggested an off axis cat I was not aware of Yolo but your suggestion has made my suggestion a lot more doable.

    • animalsbybarry

      I would have asked exaxtly the same questions but you beat me to it..this time.
      I do indeed wonder when and if Sigma will offer bothe the 150-600 sport in A mount and the 2 new high quality teleconverters.
      I own both of thier previos apo converters but these new ones sound worth upgrading to.
