I have no wish to criticize the M5 or the article - I suspect that the M5 will sell, especially to loyal Canon consumers and those who already have Canon lenses they might use via smart adapters. OTOH, the greater limitation of the M as a system is the sheer lack of glass. The other mirror-less players have steadily been developing a range of excellent native MFT and APSC lenses - that is where Canon have let their mirror-less system down.

I'm quite confident that Canon will enter the mirror-less world seriously soon or later. It might even be in FF. The signal that they are doing so will be when they announce a range of dedicated high end lenses.

The Contax/Zeiss Sonnar 85/2.8 and Sonnar 90/2.8G were wonderfully sharp small light lenses, so this lens has a strong heritage. I really like the Loxia concept but why is this one so heavy? At 600g with the caps on, surely that's over the top for an f2.4 lens? Many RF 90mm lenses and some faster DSLR lenses are significantly lighter. Not as attractive as it could have been for lovers of light weight kit.

And, on the Loxia range, can we please have a 25-28mm in Loxia design too?

Love the traditional design with a real mechanical MF implementation and an aperture ring. It's great to be able to see settings at a glance.

And generally - good to see more WA MF lenses coming out in mirror-less registration. It's a pity only a few of them are optioned in Fuji mount.

Looks like an interesting lens, especially if the IQ is as good as touted. It could have had a wider appeal if they had marketed a version with a mechanical aperture. The electronic aperture will prevent it's use on earlier SLRs/DSLRs and its adaptation to some mirror-less mounts. Maybe they'll offer it later in other mounts.... Pity, but first let''s see some tests and reviews.

Thanks DPR. I've been watching Charlie Waite for long time - one of my favorites. And some great images from other photographers too.

C.A.S.: Another MF wide-angle lens without hyperfocal scale. Absolutely unforgivable.

Yes, I believe Zeiss are trying that with the Batis line for Sony. (I don't think you can adjust the COC though, but I may be wrong - I'm a Fuji user. In any case, for a WA, I'd personally rather have a Loxia with the traditional scale). I'm cautious about electronic distance and DOF scales - the concept suffers from more complexity than an engraved scale on the lens. In the Fuji system, there is a problem that the distance displayed in the EVF from the fly-by-wire data isn't always accurate. It seems to be better with primes than zooms. And if the distance is incorrect, it doesn't matter what the COC is, the calculated DOF will be incorrect anyway. And you also have the weird situation where the COC for the DOF scale in the EVF may be different from the one on the lens (if it has one). Just to add some complexity. On reflection, I still think I'd rather have the scale on the lens.

Hi,
Great shot, well done. The FL of 240mm seems incredibly short for a tight birding shot. The heron must have been hunting incredibly close to you. Is that actually right? I'm always struggling to get close enough with a 400mm!

Cheers, Rod

@ N Contrarian. True, but I suspect that the simpler reason the DOF scale has been omitted (as per some of their earlier lenses) is that they are marketing it to users of multiple systems. No DOF scale could be even remotely accurate for every sensor size between MFT and FF. At least it has a distance scale..... Many don't - a product of focus-by-wire design and a sacrifice to AF - the throw is so short (to increase AF speed) that a DOF scale would be compressed into a small range (eg Fuji 16 & 23mm).

OTOH, I do sympathize with C.A.S about the lack of DOF scales on OEM WA lenses designed and sold for their native sensor. Yes the manufacturer has to choose a default COC, and indeed it may not suit every image, but it's not that hard to make an adjustment if one wants to shift it from (say) the common default of 0.02mm to maybe 0.01 or 0.005mm. Better to have a scale and adjust than to have none at all (IMO).

sportyaccordy: Key spec will be the weight.... could be a cool replacement for the 17-40. I could see this doing really well for low light group shots and night scenes

Hoping their next release will be AF FE mount though....

The DSLR versions weigh a tad under 500g. The mirror-less lenses weigh over 500g, no doubt because of the longer barrel. It takes a 77mm filter. It's quite solid and certainly not a small or even medium-sized lens for mirror-less systems. Whether it is attractive on smaller formats will therefore depend very much on the IQ - as always - but more so if one is to consider opting for a large lens.

Rod McD: Great video thanks. Every time I see one of these tear downs of modern Sony (Fuji, Nikon, whatever) AF, OIS lenses, the more I'm impressed with the engineering. Unfortunately at the same time, the more convinced I am that the lens is as complex a device as the camera and just adds to the potential to wear and/or go wrong. Who will be able to repair them and how long will the parts be available? To me, it makes traditional helical MF lenses like Loxia, Samyang and Voigtlander look more attractive.

@ Mr Scrooge. I never suggested a comparison of any kind. I suggested that you test your own hypothesis that high volume AF 18-55 kit lenses will be the most repairable lenses in decades to come. My own view is that they will be the ultimate disposable lens : parts unavailable, uneconomic to repair, and 'fixed' by replacement. The only way to test your hypothesis is to actually follow it through. You seem reluctant to do so.

I'm not that interested in further debate about the potential future servicing of any lenses. I already use lenses of both types - but I'm clearly more confident in the longevity and serviceability of simple mechanical lenses than more complex electronic ones. Certainly my actual experience and that of a few acquaintances trying to get parts and repairs for relatively recent gear helps underpin that view. If you predict the reverse will be true, that's absolutely fine.

No-one knows with certainty the future availability of anything. Why would you have expected me to? It's always about assumption and projection based on the present. Nothing new there. An array of lubricants suitable for lens helices is available today. I predicted that they'll be there tomorrow. Let's see.

Perhaps you could test your projection too - find some recently made and broken AF OIS 18-55 lenses, put them aside, and try to get parts and repair services for them in ten years, again at twenty years, and again in perhaps thirty years time - as old as my oldest MF lens I can still have lubricated. There you go - a longitudinal methodology for you to test your hypothesis. I've already had to toss out digital gear less than six years old for lack of parts for repair, so while I wish you well with that, my recent present experience is perhaps the basis for projecting some doubts........

I'm wondering exactly what your point about assumption is and why you make it. We cannot know the future and we only ever make predictions about the future based on what we know about the present. And since the need for long life, low temperature, non-gassing lubricants is so widely needed across industry for new cameras, new lenses, telescopes, microscopes, rifle sights, theodolites, electronic and medical equipment, etc, etc, etc, I think people who need them will find them available. Assumption? I'm writing here today, not 2026, so yes. Would it deter me from buying an MF lens? Not in the least.

It can go either way - lubricants can dry out, wear out or evaporate and lenses can consequently either stiffen up or become too loose. Others are fine forty years later. I'm not personally involved in repair. I send mine to a local repairman in Adelaide, South Australia. (Don't know where you are.) I've watched him do my lenses. It seems to involve removing the mount, extending the lens to expose the helix and slowly working his way around the helix, placing specific grease into the helix channels with a syringe fitted with a large bore needle. He's very careful about the choice of lubricant - viscosity, sublimation etc. Can't tell you more than that, I'm afraid. I'd be confident that a competent repairman specialising in the repair of mechanical cameras, lenses, telescopes, microscopes, etc would have access to suitable lubricants.

Wow, that's quite something. What a feat of road-building. And an extraordinary place. Was the image shot from another point on the same road? Or a nearby peak or helicopter? Whatever, it's a great shot.

@ MrScrooge The lubricants are still readily available today and I would expect that they'll remain so as long as there's a demand. One look at e-Bay will tell you that there's a thriving usage of older lenses and since they last very well, and since new MF lenses are still being made, I'd expect supply to continue. And if it doesn't, industry is so diverse, that there are bound to be excellent substitutes. I have both AF and MF glass, and I fully expect my MF primes to outlast my modern and complex AF OIS zooms.

Haven't Voigtlander been selling 10/5.6, 12/5.6 and 15/4.5 designed-for-digital FF rectilinear lenses in Leica M & Sony FE mount for the last year or so?..... Edit - just saw it's the widest f2.8 lens......fair enough.

On article SLIK introduces SLIK LITE tripod line (35 comments in total)

I like their 634CF for a backpacking tripod and these look closely related. I can't say that a light in the bottom of the center column looks all that exciting. Once you've set up the camera, there can only be one place the light can be shone - downwards. It'll be quite useless for illuminating camera and lens controls. Is there anyone who sets out to do night photography who doesn't take a head torch or handheld torch with them?

And would somebody please inform Slik USA that the internet is an international phenomenon - showing both imperial and metric specs in their site might just help potential buyers consider their products.

In reply to:

Rod McD: Interesting. No doubt priced to compete with the 50mpx Pentax 645Z and far lighter. It will appeal to many. Having said that, I don't think I'd personally enjoy the design. The body and lenses are virtually devoid of the dedicated controls that I prefer and the lenses have no scales or markings at all. Buyers will face a limited lens range and no ability to adapt other lenses. Not for me. It'll be interesting to compare it with the much-tipped Fuji if the rumors are borne out later this year.

@ surlezi Who said they preferred a non-existing system? What I actually wrote was that it will be "interesting to compare it with the much-tipped Fuji if the rumors are borne out later this year".
