Azfar: Has dpreview changed its 'Review' format ? Four pages ?

Well, it's a little m4/3s camera, so that's the equivalent of 16 FF review pages.

400mm, f6.3, 67mm filter? Damn. That's cutting it close.

In reply to:

Tieu Ngao: A review from CAMERALABS says that "the OS is not very effective at 400mm with shutter speeds around 1/100 sec and 1/50 sec". I suggest that DPREVIEW should have photos taken with that shutter speed range next time. Thanks.

I will. I'll even use 400mm on m4/3s (800mm 35efl) at 1/30 - 1/50.
Very useful to be able to do that if required.

In reply to:

Internet Enzyme: Seems slow. F/2.8 to F/4 is a F/5.6 to F/8 full frame equivalent. I do understand that that probably doesnt matter much since this is meant as a wide landscape lens, where long exposures negate the issue and slow apertures are necessary to get everything in focus. But if you plan on using this lens in any other capacity, you will be very disappointed in just how much noise that the lens will produce.

This particular lens is clearly trying to strike a balance between size and aperture, and fits into the new range of f2.8 - 4 lenses from Panasonic. Fortunately for M4/3s we have several UWA's, ranging from a 7-14 f2.8, a 8-18 f2.8-4, 7-14 f4, 9-18 f3.5-5.6, and a whole bunch of fisheyes.

Why would someone with a legitimate interest in the topic, start a discussion at 1am? Especially when they already know and presumably understand the trade off of IQ for size (as they own an RX100). That suggests pretty strongly that they aren't really interested in the discussion, but just want to stir the pot a bit.

I think you knew exactly what you were doing. You just wanted to do a bit of trolling.

Are the photos taken with the 8-18mm more impressive than the photos not taken with a hypothetical FF rig with a 16-36mm f2.8-4 lens that was left behind because it was too heavy?

Kinda like an RX100, right Internet Enzyme? :D

Second recent false report from Nikkei about a camera company dismantling their camera division.

Now I'm intrigued as to what's going on at Nikkei.

King Penguin: I'm amazed!

Rain forest destruction, oceans poisoned by pollution and plastics, corals dying world-wide due to warming seas, fracking polluting underground water resources, mass wildlife extinctions due to human activity, etc, etc, etc and commenters in the 2nd largest poluting country in the world are getting upset about a few tyre tracks in the desert!

Sorry guys, it's a bit like a passenger tidying his sock draw as the Titianic goes down.......

It is possible to do more than one thing at once. Some people can work on keeping the national parks in good condition, and pulling vans out of salt pans. Others can work on stopping pollution, or climate science, or wildlife conservation. Maybe the commentators you're speaking about are concerned about the big and the small. It's also possible they're tidying their sock draw, but I wouldn't tar all with the same brush.

On photo Magic die in the Games people play.. challenge (4 comments in total)
In reply to:

CelticOdyssey: 5 seconds??

The trick to this shot, is that there's a big shadow region behind the dice that you can't see from the camera (because the dice is in the way). The dice is supported by a paper clip and counterweight, that is superglued to the back corner of the dice.

Yep. Probably longer actually. It's a live composite.

Peiasdf: On the other hand, there is excess inventory of E-M1 II because no one is paying $2000 when the same money gets you GH5.

Clearly you didn't try and buy an E-M1 II when they were released. key word "try".

Martin.au: Wow. I took a Thinktank Perception Pro (2.9lbs/1.3kg), an M4/3 E-M1 and five lenses (average weight 400 grams), a 15" Macbook pro, an iPad, and a few accessories overseas recently. Even with that comparatively lightweight kit I hit 8.5kg. I can't imagine what this bag with a full load would weigh.

Errr no. The full load of this bag (as I specified) is a hell of a lot more than what my little backpack carries. No way would you buy this bag to put a handful of M4/3 gear in.

And, obviously 12.17kg is well over the airline carry-on limit.

Using the fully load example in their article, of a 400+gripped DSLR + other stuff suggests that that bag fully loaded may come in at around:

4.9kg - bag
2x0.8kg - 2x5D IV
3.85kg - 400 f2.8
0.4kg - grip
0.76kg - 70-200 f4
0.8kg - 24-70 f2.8
2kg - Macbook
0.5kg - iPad
2.2kg - Accessories (same as my bits and pieces, laptop charger, etc)

For a weight of around 17 kg.

Looks similar in design to their Perception backpacks, which are actually an exceptionally useful design.

The main advantage behind this style of pack is that you can fill them up with camera gear for some events, and then change out camera gear for other stuff when the situation calls for it. eg: If you are photographing stuff in more remote conditions, then you may take a camera and a couple of lenses, and stuff a waterproof jacket, food and water in the lower part of the case. The pouches just squish down (or in this case be removed) to gain back the space needed for other stuff.

Obviously, if you just want a big padded case to carry your camera gear then this isn't the bag for you.

But the earth is flat, just ask a surveyor. :D

SnappyUK: Question: Orienting the picture so the right front wheel is in the centre of the shot, move the viewpoint up a little to look at the repeating pattern of indentations - that look like wheel tracks - which do not have the same tread pattern as the rover. Weird!
Any thoughts as to what (realistically) may have caused them? Because I can't see any tracks from the rover on the terrain in any case.

They do have the same tread as the rover. Remember that in most cases at least two and probably three sets of wheels have driven over the same ground, and it's unlikely they'll be in the exact same tracks (I think the middle wheels have a wider wheelbase).

Either that, or it could be this pattern you see.
