Dear Canon,

Why don't you make it a 24M so that my Mom can have enough pixel for her Facebook posts?

Regards,

Except Sony, this is painful for everyone.

On Leica unveils D-Lux 6 Silver Edition article (92 comments in total)

In China, this makes great gift for a manager or party leader who has no idea and does not care how good/bad it is as long as it has a luxury brand logo. L or H's management understand this and they know such products have nothing to do with photography. People who buy this want no part in good picture taking. Therefore, this is a very logical product.

These images show that the photographer is definitely at NG class regardless tools used. I hope I can get back with images close to these even with Nikons.

However, the decision of leaving camera with a brand and bring a phone of a brand to a costly trip always demand questions. What;s the agenda? is it/are they:

1. Here is the beautiful Scotland, come visit. (We know before hand)
2. iPhone x can take beautiful images if used in right situation. (We've been shown many many times)
3. I will use iPhone x instead of Nikon in my future trip. (really?)

I will be much less confused if the story read "When I open my case at our first camp, I was shocked that, except my phone, all my gears were damaged by radiation during the fight...."

Hongze: What the heck is "light gathering capability"? I am so confused by the formula someone come up with - "42.5/1.2 = 85/2.4 = 35.4mm". Is a 1.2 lens 1.2 regardless of their focal length? If two lenses can project the same amount of light to per square inch/cm of sensor, do they have the same "light gathering capability"?

Please help me to make sense the "42.5/1.2 = 85/2.4".

Hi Guy,

Thank you. You clarified the issue. I have a old Canon 300D (not a FF also not a 4/3 either) and 17-40, 70-200/4. After evaluating the price and weight/size of a 6D, I bought a GX1 and a 14/2.5 for the amount of hiking I plan to do. I found converting the actually focal length to a equivalent 35mm field of view helpful when buying a lens.However, when using a lens, I found the conversion is irrelevant. I got whatever the lens produce.

Then, I saw this formula which list all 4/3 lenses like 20/1.7 = 40/3.4, 25/1.4 = 50/2.8, etc. Because I use mostly A mode, the formula seems indicating that the shutter speeds should have been doubled on GX1 comparing to (or thinking of) a FF camera. Then, the question rises. What if I am thinking of a medium format camera? which makes it funny.

Thank you for the replies but I am still confused because you were talking about comparing with 5D or FX. Why are we comparing with 35mm not, say, a medium format which may give us another formula 42.5/1.2 = 175/4.8? If the formula is right, should I always compensate my exposure on my GX1 if I do manual exposure?

Matching DOF is even more confusing to me, I can't think of a case that I need to match another camera's DOF when I am using a different one. Oh, does that mean "DOF of 42.5/1.2 on my GH3 == DOF of 85/2.4 on FF"? Then, what the heck is role of the "light gathering capacity" in this formula?

On Panasonic GX7 First Impressions Review article (1201 comments in total)

After using GX1 with LVF2 for some days, I will say the electric view finder for a mirror-less is a must for anyone who enjoy the picture taking process. The way that time freezes in the finder after you press the shutter release is just wonderful and dream like.

With the high quality finder built in GX7, Panasonic is showing their efforts to please ppl who think such a finder is an integrated part of picture taking.
