    Interested in picking up a super telephoto lens.

    I know that this lens is expensive... and large/heavy. I'm prepared to accept that once optical quality is very good. I've used a Canon 100-400LII previously and was very happy with that, sometimes wishing for longer reach. Conversely I've also shot Pan100-300 on m43 (600mm equiv reach) and often wished it performed better at the long end.

    Has anybody here tried the Tamron 150-600 or 70-400 with LAEA4 on A7 system? Care to comment?

    I would like to hear about this too. Unfortunately, I would only use that lens with the A7ii to have a stabilization option, as it doesn't have its own OSS. :(

    This guy has a nice write up of LAEA4 + 70-400...

    His photos are stunning - I suspect that he is just a good solid photographer that can make any system or camera sing.

    I tried it on my A7ii in a local shot yesterday. Shot 400mm and 1/8 second hand held and ISO6400. It worked quite well. Maybe there is the slightest lag between pressing the shutter and taking the shot - relative to a fast FE mount on A7ii (which is very fast and snappy). But very impressive glass all the same.
    My only question now is whether this will be a better buy with an A7ii + future APS-C FE or just get 150-600 tamron?

    Yes that exactly what I am talking about - hoping for an APS-C E-mount with IBIS that can also use the 70-400. Although the A77ii supposedly works fantastic with this lens!

    The Tamron 150-600 looks lovely - although the Sigma 150-600 sport also looks lovely but unfortunately not available in A-mount. Contemporary model is available however. Neither lens look to be as sharp in the 100-400 range of e.g. Canon 100-400LII , Nikon 80-400G or Sony 70-400 G2. Which makes me wonder whether the 100-400 is 'enough'. Obviously

    A few other considerations that I have - 70-400 on APS-C will provide equiv field of view of a 105-600 on FF. The slightly wider short end would make it good for portraiture both on FF and on APS-C where it would be 105mm equivalent FOV.
    On the long end for APS-C, 600mm is enough. However on FF where it would be used most of the time, I find myself questioning whether the 70-400 would provide enough reach given that I shoot wolves who don't like to come too close to me :)

    One big advantage of going 70-400 is that it fits into my camera bag :)

    Real Name:
    I just received my copy last week after reading Phil's review and going for it. Great lens for my liking. Using it on the A7R and the A7S with the LAEA4. I was worried about the focus speed for sports/birds. However it is as great as they say - focus is every bit as fast as my Canon 70 - 200mm F2.8. And to my eyes the sharpness is there. Maybe I am lucky with my copy but I haven't faulted it yet.

    Only thing worth mentioning and it is obvious from the specs with the limited aperture F5.6 and no stabilisation - a monopod or tripod is essential. So that is a limitation.

    I haven't really done any detail tests - these are just general observations.

    I also shot video with it on the A7S. The focus was smooth and relatively easy to pull.

    Here are some shots I took on the weekend. If I zoom in on the tall ship to 1:1 I can see the rope windings.

    Long exposure fully zoomed out 70mm. ISO 50, 2 seconds, at F4 on Tripod.


    400mm, ISO 320, 1/1000 - 1.4m from the subject on Tripod it still resolved good detail in the leaf and at full zoom which is thought to be soft. Leaf veins are strong in detail at 1:1.


    The bokeh is also lovely, as contributors on a Canon forum commented for this photo.

    230mm, ISO 200, 1/160th


    At high shutter speed (1/2000th) in the mid zoom (135mm) - wide open (F5.6 minus one third) on monopod. 1:1 detail on the Athlete's eyes is perfect and the continuous focus picked out the faces at 10 metres and tracked them right over the jump.
