Robert Callway: 50mm Summicron – The Right Kind of Everything

This is a guest post by Robert Callway, who has his own production company Nilsfilmwhich produces corporate promos and documentaries. Also a cameraman and occasional photographer, Robert has shot a number of prime-time award winning C4/BBC documentaries including this year’s C4′s “Battlefront” (Digital Emmy) and BBC’s “Remembrance-A Sikh Story” (RTS Award). 

The last lens I wrote about on the Leica blog was the 50mm Summilux ASPH. A lens that took me by surprise with its incredible detail, aperture, etc., but … but I didn’t gel with the lens as much as I hoped. Call me “finickity”. Call me “slowcoach”, but I always had trouble with focusing quickly with the Summilux. But when I got it right, the quality of the photographs were outstanding, superlative. However, I want and need to have a higher hit-rate as most of my photography is street style/documentary. I don’t want to wait on myself trying to get the focus right before the shot disappears.

So in the end, I had to wave goodbye to the “world’s best” Leica 50mm Summilux ASPH.

Say “Hello!” Leica 50mm Summicron!

Purchased through the excellent Leica Forum trade. I opted for the a new chrome version of this legendary lens to match my new chrome M9. I had read so much about the Summicron on the web and wasn’t sure what to believe. How could a lens, originally designed in the 1950s, have kept photographic standards so high that its optical formula is still used in today’s latest designs?

As soon as I mounted the lens on the M9 I fell in love. The focus throw was perfect. The aperture ring, perfect. The build, perfect. The design, perfect.

But the proof is the lens in action. Would I take more useable pictures than with the Summilux?

I noticed the difference immediately. It helped that I now had a digital M rather than my ol’ M6. But even if I had the M6, I was confident that the Summicron would hit more than its f/1.4 partner. I also starting noticing something else — the incredible sharpness and gorgeous bokeh. I thought the Summilux was sharp, but the Summicron is definitely sharper, in fact, the sharpest lens I have ever used. I am not super mad about the sharpness, but I would rather have a lens that delivers it than not. For portraits, the Summicron, in my humble opinion, has just the right mix of sharpness, micro-contrast and close-focusing. I love great micro-contrast on wide shots, but on portraits this can be a disadvantage as too much detail is captured. I found that I have had to spend longer in post-production trying to flatter the subject.

Bokeh is so subjective. Some Leica-philes describe the bokeh out of the Summicron as busy. After having the pleasure of owning not only the 50mm Summilux ASPH, but also the “King of Bokeh” 35mm Summicron V4 and 90mm Elmarit, I have to say that the 50mm Summicron more than stands up in the bokeh stakes and when you are close-focusing the bokeh beautifully flutters the background away. On mid-focus subjects, the bokeh really helps your the image pop.

All you have to do is look at some of the images that I have accompanying this blog post. A mix of family, friends and the odd wide and documentary shot not only shows the qualities of the Summicron 50mm, but also its flexibility and usability.

So can I add anything new to what has been written before about this lens? Well, no. I can only reiterate it. With all the new rockstar lenses that have recently been released, it is worth remembering that there are great Leica lenses available that still set the standard and will for years to come. I actually heard of one collector who snaps up every secondhand 50mm Summicron he comes across because just because he thinks it is the finest lens available.

There are on-going rumours that Leica has been working on a Aspherical version of the 50mm Summicron. If it’s true, I can’t wait to try it out, but it is hard to imagine a more perfect mix of everything.

  • Interesting read, I just caught up on your Summilux article as well.

    I’m especially interested in your comment about the Summicron being easier to focus – could you expand on that a bit more? Is this just a matter of preferring the ergonomics? Or do you mean easier when shooting wide open?

    I jumped ship from DSLR and bought a used M8 and 50mm Summilux sight unseen, the only Leica lens I’ve ever used so I’m very interested in learning about other options.


  • hi mugget….i felt, and i am not the only one, that the 50mm summilux asph had too much focus-throw and because it also has a floating element i.e. a lot of glass moving inside…the focusing was quite heavy and not smooth like the summicron.

    that was my experience with this lens…others may differ.

    the summilux is incredible but that is the trade-off.

    if you are buying the summilux secondhand I would buy it and if its not for you…sell it for what you paid for it and get a summicron instead.

    hope this helps…bob

  • Great info – thanks Bob for your reply.

    Maybe a big difference in my case is that I have a 40 years older non-ASPH Summilux, which I believe doesn’t have the floating element. In any case it sure sounds like the Summicron is worth looking into! (Haha, can’t miss a chance at a good pun!)

  • I’m one of the few who didn’t get along well with the 50mm Summicron. I had some focus issues and flare problems. I traded it back in towards a pre-ASPH 50mm Summilux E46 which while not nearly as sharp, I can focus much easier and all my flare problems have gone away.

  • dan….would agree with flaring actually but its like 1 in 99 shots with me so don’t notice it. did you have latest version ? i have no problems on focusing…would love a go on a pre-asph lux to see whats different between it and asph vers.

  • Cheers Chester! Been a great response to article…quite a lot of messages have come through to my email as well. Appreciate them all.

    I am looking forward to writing next blog about the 35mm Summilux Asph. V1!!

  • Great pictures! I like them all, but the Dad photo, #8 and #9 are outstanding!

    BTW, have you maybe had a chance to use ZM Zeiss Planar 50 f/2? Would be interesting to see how you’d test it 🙂

  • Great images and a great lens. The latest 50mm Summicron was my only lens for a while and is what 90% of my shots are taken with. Now supplemented with a 28mm Summicron.

    If I could only have one lens it would be a 50mm Summicron. As it is I only use two lenses anyway.

  • Domagoj….cheers. My Dad actually doesn’t like that shot but liked that I got it on the Leica blog! I told him it was either that one or the one of him in a turkey costume!! He is a big Leica fan and introduced me to the M6. I haven’t had any chance to use the Zeiss which I hear is outstanding. I do have a Voigtlander 50mm 1.4 but hardly get used since I got the Summicron…which is superior.

    Mike…yeah it’s a superb lens. I got a Summilux 35mm Asph. V1 to complement to take my low light shots and a wider POV. It is magic at 1.4 and handier for street sohts…likewise your 28mm ‘cron.

    Thanks for the messages
