If you really don't care about f1.4, and can afford the extra for rx1rii, get that and sell the 1.4. i do care about 1.4; I find that the 1.4 combined with eye focus opens up a new era in wide ...

Possibly a bad sample; though it seems to be symmetrical (though to be sure we'd need to know how many measurements DXO takes to generate the field map) But even more likely I think is that it's a ...

Best or most expensive? Best is always relative to purpose; for some an f2.8 zoom is what is best, for most who need zooms I think Jim is right and an f4 is best (if it's a really good f4; in ...

In general I completely agree with Jim; but not about a 35mm 1.4 In fact this is the only focal length where I prefer a 1.4. 50 and 85 mm lenses have plenty thin enough DOF for any effect I want at ...

(1) Don't get an A7r. It's a nice camera, but it requires a lot of thinking about shutter speed to avoid vibrations that reduce the resolution to the point where you'd be better off with a ...

Hi Magnar It was done with daylight; I later did an infinity test on distant buildings and the results were similar. I haven't done really close (the ApoLanthar is fantastic really close, so I ...

Hi Geoffrey. What he means is the A7rII and the sII have the same high ISO performance when you view images at the same actual image size. Even DPR agrees: it isn't controversial. Of course if you ...

Some of you may recall that I've recently got an Apo Lantar 180 at extortionate cost for an old lens that was not pricey at issue, but at a reasonable price given the going rate! I got it primarily ...

Actually the 90mm G macro has a linear mode. If you manual focus with the focusing ring in normal position by switching to manual on the camera  it foucces in non-linear mode (which has some ...

With a brand new format? Could that mean sensor size?

I would be very surprised if the smearing were an adapter issue; the lens is made for SLRs so there will be no corner issues aside from ones the lens has on every platform. Is the smearing at f1.4 ...

If it's informal people photography you like to do with a 35mm lens I wouldn't go Loxia; you are missing out on continuous eye focus, which is one of the most fantastic benefits of the newer A7 ...

Fair enough! I take it though that you are getting a more or less circular fisheye image on FF? Which of course is maybe what you want..

I Wouldn't let the lens tip review turn you off if you are interested in the 12. I have a nice copy of the 12 that seems much better than th cooy they tested on the edges. This is Samyang! Copy ...

I'd rather that discussion of lenses is integrated with the rest of the lenses for a platorm. If I want to know about, say, 28 mm lenses for Sony I think the OM Zuiko, the SMC pentad, the CY 28, ...

Maybe, but OSS is supposed to be better with the hybrid mode where you use the lens for two axes and the IBIS for the other three. So if they want the best performance they will include OSS (and ...

There's a third option - which we see far too little of - which is relatively slow for the focal length (like an f 2.8 40) but *absolutely not compromise amazing*. In theory you ought be able to ...

My claim was just that the level of centering was very good for a 20 1.4 - not hefty at all of course there are very few such fast super-wides. And of course you would expect much better ...

On a tripod M+ Auto ISO will give you in many situations too high an ISO I either set the ISO to 100 and use A mode, and let the shutter speed be changed, Or else I use M mode with the ISO set to ...

hefty decentering? That's actually pretty good for a 20mm f1.4! The sharp area is nicely centred, the corners are soft and a couple are much softer than others. I doubt if there is any fast UW ...
