Re: SR-mount lenses, what's hot or not!
Actually, there was one better Rokkor—the 50 mm f/2 MC Rokkor issued immediately before the 45 mm MD. Hey—I love it when others come to the same conclusions, with regard to lens performance, as I do. I also found the MC Rokkor-PF 50 mm 1:2 one of Minolta's best standard lenses ever. It is at least ...

Re: Minolta AF Apo 100-300 mm or AF 75-300 mm Beercan
The Minolta AF 75-300 mm 'Beercan' used to be my workhorse telephoto lens on both the Konica-Minolta Dynax 7D and Sony Alpha 900 ... until I got the Sony SAL 70-400 mm G SSM which is even better but also significantly bigger and heavier. I compared the AF 75-300 to its own successor models of the sa...

Cameracraft arrived
My copy of David's new magazine 'Cameracraft' arrived today. It feels thinner than expected but still has a lot of content; it makes you realise how many pages are wasted to advertising in other print magazines. The print quality is extra-ordinarily high, and it on many pages the spirit from the old...

Re: Full-frame rumour about NEX—is it possible?
Huh!? :shock: All of sudden, everyone is discussing 'the upcoming full-frame NEX'? Where does this flakey rumour come from? I am pretty much sure there won't be a full-frame Sony NEX ... not next week, not at Photokina, not in any foreseeable future. It simply doesn't make sense. Or rather, it would...

Re: Zeiss 24mm f/2 review now posted
David, are you aware of photoscala's review of fast 24 mm lenses they did in May 2011 (in German language)? The test included the following lenses: Canon EF 24 mm 1:1.4 L USM II Nikon AF-S Nikkor 24 mm 1:1.4 G ED Sigma AF 24 mm 1:1.8 EX DG Sony SAL Distagon T* 24 mm 1:2 SSM ZA Leica Summilux-M 24 mm...

Re: Sony 70-300G Auto-Focus with Polarizer
But I think you problem is not because the kind of filter, but because the amount of light: at 300 mm, your lens is a f/5.6, and your polarizer takes about two stops of light. Usually camera makers recommend f/8 as minimum for the AF system working properly. A polarising filter (or any kind of filt...

Re: Sony 16mm Fisheye and DXO
Pako, you've said that correcting fisheye would get at 20 mm. That would be true for a 14 mm fisheye with distortion close to that 8 mm Samyang. That's nonsense. Pako's statement about the Samyang 14 mm wide-angle lens and his statement about correcting a fish-eye lens appeared in two separate para...

Lightroom 3.6 and Camera Raw 6.6 RC available on Adobe Labs
If it's on Adobe Labs (rather than Adobe.com) then these are just release candidates, not the final releases (which can be expected to appear four weeks after the release candidate versions). Sometimes, new cameras are inofficially supported by new ACR or LR versions ... that means the raw files can...

Re: Minolta Creative Cards
The Sports 2 card is perfectly compatible with the Dynax 9xi and is particularly useful in conjunction with the AF-xi 28-105 mm and AF-xi 35-200 mm lenses—i. e. those AF-xi lenses with extra-wide zoom ranges. The electrical connection between the card compartment in the hinged card door and the came...

Re: Fairy tales about 'diffraction'
Image-side telecentricity is a pretty common thing among lenses designed for digital cameras. The sensor nature simply requires that. (Actually, every cheap superzoom in existence becomes very much telecentric at its long end.) Yeah, sure ... :roll: If you are a professional physicist then I am Pet...

Re: Fairy tales about 'diffraction'
I didn’t think that extended objects produced Airy disks, or do they? Of course they don't—simply because extended objects are no points. Still, Airy disks are more that just a theoretical concept. Any image in fact is composed of a virtually infinite number of partially superimposed Airy disks of ...

Re: Fairy tales about 'diffraction'
Telecentricity means the exit pupil at infinity, by definition. Exit pupil at infinity means the output flux is always collimated, regardless if lens is focused or not. Sure. But first—telecentric lenses usually are not found in the average hobbyist photographer's closet. And second—they're not req...

I've been using a Bellows 1 with my cameras for a long time. I bought it used a and it came with a slide adaptor. Has anyone ever tried the slide adaptor with APS-C? [...] with the crop camera and a 50 mm lens I'm having trouble getting the whole slide in the frame. Too much magnification, so I won...
