    I have an extra older computer that I don't use much and that is the one I will sometimes download software to just try out. At the moment I have it packed away so maybe later I will get it out. The last time I downloaded darktable I put it on that one. It also […]

    Yeah, several companies are coming out with rather slow FF lenses which are smaller than the faster FF lenses. IMO, one can't compare to the speed of old film lenses though. In film days ASA 100 was about as fast as I went with slide film -- slide film speeds that were the best were […]

    I did toy with the A7iii, at least a grey import one which is more reasonable priced (pros and cons to that take). I'm just not sure it's going to be a particularly good purchase at this time, I gain video features (which are not super important right now 1080p is fine for the videos […]

    I have a nice selection of A-mount cameras and lenses. I'm not like the Invicta watch collectors. I don't have any of the long tele lenses that you mention in your posts, except for the Tamron 70-300 f4-5.6, which I value, but wish it was much lighter. I use it with the a65. I also […]

    I have picked up a Minolta 80-200mm F2.8, it's coming from Germany photo dealer with warranty. Based on the serial no. it looks like a late production one in very nice condition, but it's not turned up yet. I'll let you know how it goes, I have a return if needed 14 days hopefully it's […]

Sony FE Macro 50mm f/2.8 – only $500

Sony has just announced yet another 50mm, and this time it’s different – a truly affordable 50mm 1:1 macro, only $500 US. We reckon this will become the most popular standard 50mm lens by far, even more so than the budget 50mm f/1.8. Now you can photograph your food properly at last!

or-sel50m28---3quarter

It certainly looks neat and the specifications are good.

It features one ED (Extra-low Dispersion) glass to reduce lateral CA (colour fringes) as the image scale increases. The optical and mechanical construction of the lens is claimed to have less glare and ghosting. The lens is also dust and moisture resistant.

Examples shot with the new lens can be found at www.alphauniverse.com, Sony’s new corporate pseudo-community site. We have to say the bokeh looks funky, not good, and this lens probably lacks the classical drawing of the more traditionally designed (and more expensive) SAL 50mm f/2.8 Macro A-mount.

or-sel50m28---controls

The 6.25″ (16cm) minimum focusing distance is a clue why. The effect of the 7-blade circular aperture design can be studied in the Sony photo examples. It has a focus-mode switch, focus-range limiter and focus-hold button (the mode switch is valuable as you may not want AF for macro shots most of the time, and the focus limiter is similarly good for controlling frantic hunting and missing – all three switches/controls are important on the mirrorless bodies).

or-sel50m28---macro-convenience

The lens is 7cm long, weighs 235g and during focusing it extends in length by only 26mm, not the 50mm required for a typical Tessar-type lens of this focal length. This, and the minimum focusing distance (should be at least 20cm for a 50mm macro at 1:1) indicate that the design relies heavily on internal/rear focusing groups, much like the 30mm f/2.8 DT SAM macro for A-mount. We would reckon the true focal length of the lens at 1:1, which can not be more than 40mm with a 16cm close focus, may be around 35mm as 1:1 is achieved with 76mm of overall focus extension.

The distance from the subject to this lens front rim at 1:1 is only 3.5cm which many will find a little too close for insects and even for plants, as the shadow of the lens and photographer may interfere. Even the SAL 50mm is not perfect, reaching 1:1 at 20cm from the focal plane with a 48mm dual barrel extension and 53mm front element focus travel (the extra 3mm is down to floating element correction which slightly changes the focal length). This places the lens rim 7cm from the subject, twice the working distance relative to this new SEL FE design.
