On Fujifilm X-T10 First Impressions Review preview (369 comments in total)
In reply to:

iudex: s there any reason for limiting ISO 100 to JPEG only? I can imagine that ISO200 as the lowest sensitivity in RAW mode is too high for a shot with large aperture, e.g. f1,4, making outdoor portraits impossible (or needing an ND filter).

But other brands (Canon, Nikon afaik) can make it in RAW and despite some negligible lowering of dynamic range it works great. Why not Fuji?

King Penguin: So this Fisheye is larger and heavier than my FULL FRAME Nikkor 16mm AF 2.8D......mmmmm, the benefits of M43....LOL.

Sorry M43 guys, but facts are facts!

mrouleau: I wasn't talking about fisheye at all ;) And I wasn't the one who started comparing m4/3 and FF lenses as well...

Actually equivalent focal length is the same and equivalent speed is f3,5 vs f2,8...

On Lee releases pricing for SW150 Mk ll filter system article (37 comments in total)
In reply to:

James Shields Photography: Why are people whinging about the cost of Lee Filters/Holders? They've always been expensive. It's kind of like complaining about the cost of a new Hasselblad - expensive equipment is always going to be expensive. If you need it and can afford it, you'll buy it. If photography is just a hobby and you're not loaded with cash, then maybe don't go buying lenses you can't afford to attach a filter system to if you know you're going to need said filter system...

That's why I'm thinking about 3d print my own holder...

In reply to:

blackcoffee17: Why the manufacturers don't use a drop-in filter system for the superwide lenses?
Yes, the lens would be a bit longer and maybe 10% heavier but
it would be possible to use small 49-50mm filters and avoid buying and carrying monsters like this Lee filter holder.

Is there a technical reason or manufacturers just don't care?

With ultrawide lenses, adding extra space for drop-in filter would complicate optical design a lot.

Gelatin filters are easy to scratch and cause contrast lost and some reflection. Not a good option.

Unfortunately only real solution are large expensive filters in front of the front lens...

bluevellet: 5axis stabilization for shooting roller derby like in the video? Tripod? Please, do not post about things you know nothing about.

"A few people here seem to be under the impression that the goal behind shooting derby is to grab a handful of shots for your blog. That is incorrect. The photos are usually for the players so they can see the bout from a more relaxed viewpoint "

The goal behind every shooting could be whatever. The goal behind this field report was to show readers that 4000$ mirrorless gear is capable of shooting roller derby. Was the goal succesfully filled? I don't think so. Images are really bad, both from technical and aestethical aspect. And it's definitely not just camera's fault, but also photographer's.

Yes, my (for example) Dakar photos are useless for roller derby people, great observation ;)

No composition, no value added by photographer, just average mindless point and shoot. I see a lot of photos like this around, but I belive Dpreview can do better. Plus the technical quality looks like it's from APS-C DSLR with kit lens.

I hardly shoot with small aperture, so I can live with it.

I have 16-35 II and found out that I most often use 16 or 35, so that's not much of a problem

Well, I believe Canon and Nikon weights include hood nad tripod mount, so Pentax weighs 2 kg, that's almost half a kilo heavier.
