Rod McD: Might be an excellent lens but sadly no use to me as a Fuji user unless it's offered in either in Fuji mount or a mount with an aperture ring that could be readily adapted. Neither seems likely. A rotating tripod collar would have been a nice pro touch too.

Good to see the conventional focus by extension. I've less time for IF lenses whose FL collapses at higher magnifications. The impact on working distance is bad news - my old MD 100/4 Macro focuses by extension and offers considerably more WD than either Fuji IF macro lens.

Yes, both Steelsring and Fringer adapters are on the market now for EF lenses on the Fuji system, but as far as the posts indicate, they still seem to be working out their teething issues with specific lenses.

It's interesting that the Canon EF model interacts with Canon cameras to do chromatic aberration correction. Obviously that wouldn't be available on non-Canon cameras. I wonder how it performs without the correction..... For the time being, I think I'll stick with my MD 100/4. It has a virtually no lateral CAs at all and very low axial CAs at apertures smaller than f4. AF is irrelevant for macro anyway. It just comes in handy when you're using it as a general telephoto.

The real test of their intentions will be the native lenses they release with their mirror-less camera and the lens road-map for further native lenses to follow. Canon tested the water with their M system, but completely failed to offer a convincing lens range in their mirror-less mount. (It was the same from Nikon with the Nikon 1 system.) It may well be that Nikon (and Canon) offer adapters to capitalize on the FF lenses already held by their existing market, but that's not going to impress new buyers or brand changers.

The 100mm Apo Macro that focuses from 2:1 to infinity and offers tight control of CAs sounds like a remarkable achievement. We don't know the full specs yet, but I'll be interested to see its images. It's not available in Fuji mount, but if the promise is borne out, adapters are cheap

On photo The Monolith in the Statues challenge (5 comments in total)

Well done! How was the sculpture lit and exposed? It looks very uniformly lit and yet it's shot into what appears to be a very bright sky. I know it's subjective, but I think I'd have been just as impressed without the upper vignetting.

I don't know why we haven't seen more images of that sculpture - it's amazing and all the more remarkable for being carved in a single piece of stone.

Thanks. Regards, Rod

Where's the LX200? Or an upgraded variant of the LX100 with perhaps slightly more reach at the long end.... ? Their exec's comments that they would not abandon the LX100 market are getting loooong in the tooth and every tipped announcement has faded into obscurity.

On article Cosina announced three new Voigtlander lenses at CP+ (95 comments in total)

Interesting how the historic name Apo Lanthar seems to be applied to multiple models with very different optical configurations.....

Cosina - please re-manufacture a run of the SL series Apo Lanthars - they're fetching high collector prices on the used market. A lot of people would now buy them for mirror-less cameras if they could afford them.

And finally, how about offering the E-mount lenses in full manual Fuji mount?

On article CP+ 2018: Hands-on with Laowa 'Magic Shift Converter' (119 comments in total)
In reply to:

WalterJ1959: Its a great idea. Their are so many older manual lenses that are inexpensive to purchase and you can now add tilt shift to them. It would be interesting to try something like the Canon FE 20mm f/2.8 with this which sells for around $200 used. Very inexpensive way to start to learn tilt shift with many lens choices. Even though software can do some adjustments, in lens will keep your crop down and your MP up.

WalterJ1959 : I just watched the whole link you included above. Nowhere does it say that the adapter offers tilt. It shifts 10mm either way and the base rotates to allow shift in any direction in any orientation. In any case, the tilt angles required for a 12mm lens would be ludicrously small - just decimals of a degree for routine J-values. So there would be very little point.

I wonder how the IQ of the 12/2.8 lens on the 'magic shift converter' on FF would compare with the IQ of the very same lens on a glass-less TS adapter on APSC..... (It would have the same FOV as an 18mm shift lens on FF). A tad less wide, but no additional glass.

As far as I can see it's shift only - no tilt.

On article Sigma introduces 70mm F2.8, first Art series macro (86 comments in total)
In reply to:

Rod McD: This looks like a very good lens and I wish Sigma would offer their lenses in Fuji mount. And nice of them to finally offer a macro lens that's relatively small. (Their 180/2.8 Macro is simply too big to schlep into the field. Who shoots macro at f2.8 anyway?)
A number of people below have made negative comment about the fact that the lens focuses by extension. I'm not sure if it's wholly by extension or whether there is also some IF focusing inside. In any case, I think it's good thing in a macro lens. It can slow AF, but AF tends to be problematic at high magnifications and most people switch to manual focus anyway. On the plus side, it allows far better working distances. The working distances of some of the IF macro lenses coming from the camera manufacturers are desperately short.

Peter, if a 180mm is needed for reach in taking a portrait, there are enough non-macro 180/2.8 lenses that will do the job and remain much smaller and lighter than Sigma's 1.6kg apo macro monster. OTOH, if a long macro lens is actually being used for macro, a 180/2.8 that weighs 1.6Kg+ is very limiting. Macro lenses often need to be hiked out into nature and they need to be maneuverable to follow bugs, lizards, etc. Interestingly enough, when Sigma first marketed a 180/2.8 apo macro, they also offered a very small 180/5.6 apo macro. They were a bit dim on an SLR but with good high ISOs and EVF gain they work beautifully on mirror-less cameras. They're now sought-after because they're so portable. I'd agree they're more for macro, and less suited to portraits though.... a niche lens.

Yes, it varies a bit with different lenses - I've never used Canon EF lenses. The specific design of macros makes a lot of difference to working distance, particularly if you're comparing one with the glass recessed a long way behind the filter rim and another with the the front element right at the front. In Fuji, both macro lenses have very short WDs. The WD of the new 80mm IF lens is shorter than that of the older (hybrid focusing) 60mm lens on a tube at the same 1:1 magnification. The WD I get from my old MF Minolta 100mm macro at 1:1 on its matched tube is double that of either. (It's a pure focus-by-extension lens.)

On article Leaked: Samyang XP 50mm F1.2 EF lens coming soon (83 comments in total)
In reply to:

Rod McD: Samyang seems to have any number of lenses from fisheye to about 135mm from memory. Very good too - but the glaring gap in the independent market is long telephoto primes that anyone can afford. Why no Samyang XP 200/2.8, 300/4, 400/4.5 or 500/5.6? Fast, but not excessively so, to keep them portable and affordable. And I don't care if they're MF as long as the glass is first rate.

Ah, yes. I'd forgotten their reflex lenses. But people tend to love 'em or hate 'em because of the fixed aperture and doughnut effect. So some good refractors of modest speed might be a good thing.

On article Fujifilm X-H1 Review (1543 comments in total)

Not for me, but then I'm not into video. I think I'll soldier on with my XT1 for the time being and check out the XT3 later this year. The size of the XH1 is expanding towards what I chose to leave behind when I went mirror-less.

I don't like the ditching of the EC dial. I know some people think a top LCD is the greatest thing since sliced bread, but I just don't get it..... The ISO, SS and aperture are an inch away on the top dials and the lens, and all of them are displayed in the EVF. Why ditch a perfectly good EC dial to repeat them in triplicate??? What a waste.

In reply to:

Ed Ingold: I have Loxia 35/2 and 50/2 lenses, of Biogon and Planar design respectively. Their construction is very solid and their operation smooth and precise. The long focusing range operates with fluid smoothness, very Leica-like. As noted, they are small (2" die) and unobtrusive. The optical performance is excellent, but generally not as good as the Batis line. There is very little non-moving space to grasp on a Loxia when changing lenses. Leica used a locking tab for this purpose, itself a PITA when focusing near infinity. I would use them more for walk-around lenses, except the 35 is longer than I prefer for street use.

My personal preference will be to take a pass on this lens. Although the Batis 25/2 is larger, it is light and has outstanding sharpness and freedom from coma. The OLED display lets you set infinity with astronomical accuracy. If the 25/2.4 (or 85/2.8) were available three years ago, my response might be different.

If you already own a Batis 25 I can understand you passing on the new lens. OTOH, for those who don't, it's impossible to compare them given that no-one yet knows the performance of the Loxia. It might or might not be sharper, have more or less coma, have more or less precise infinity setting, etc. Surely objectivity demands waiting for some tests and reports from people actually using the lens.....?

Link | Posted on Feb 15, 2018 at 01:13 UTC

The 21mm Loxia seems to be something of a benchmark. What remains to be seen is how the 25mm Loxia performs and how it compares to the Batis 25mm. Personally I'd be keener on the Loxia for landscape than the more electronic Batis.

It's interesting that this 25mm is (I think) the first one where they've made a point of the compact size. It doesn't look significantly different in size, but hopefully its IQ has not been compromised....

In reply to:

Rod McD: Can we please have the upgrade for the LX100? It's long overdue. We were told a year ago that it was in development...... I understand the appeal of the long zoom compact camera to many users but where's the high grade all-in-one option for the photographer who prefers a shorter range but faster zoom lens?

I don't know if that's the reason. If it was, surely the remedy would be to offer a tilting screen on the LX200? Personally I don't care whether it has one or not. As long as it's not a touch screen, I'm happy.
