EcoR1: Aarrg. Read some commments below and I'm just astonished by the ignorance of some people. This Panasonic lens will gather as much light as any f2.8 full frame lens when mounted on the full frame camera. There is no debate. There is no "other" truth. If you think otherwise you are wrong, and that's it . If you wan't to consider the possible size/weight benefits for any full frame lens, the only comparison must be made for the 24mm f2.8 lens. That's it people.

The proper way to look at is photon density. A FF lens will gather more light but that amount of light is also spread over a larger area. IOW, photon density is normalized. This is the basic concept of aperture. The DP article you cited discussed depth of field equivalence and not light density equivalence.

This is a huge lens especially for m43 format. I bought my e-pm2 because of its compact size. This lens is too big to be compatible with m43 format imo.

In terms of straight light gathering capability, this lens gathers more light per unit area than a f/2.8 lens because it is f/1.4. What confuses people is the depth of field. This lens has larger depth of field which is more-or-less equivalent to a f/2.8 lens. Even though both qualities are controlled by aperture, they are not the same.

This is a stunning endorsement of K-1, which no doubt is a great camera. I will buy it if I am in the market for a FF camera, but APC is fine for me at least for now. Pentax is on a roll right now, the brand that has been offering truly innovative products.

Twong: For those who want the PS technology, you can get that at half the cost by getting the Pentax K-3II. Same technology but implemented on the APS-C platform. Great technology, great innovation, great company.

The mechanical shutter in K-3II stays open during PS. This is from PF. "In order to get around the limitations of the Bayer sensor pattern, Pentax's pixel shifting implementation captures a total of four consecutive images without closing the shutter and shifts the sensor microscopically such that every pixel is exposed to all three color channels."

I think you have mistaken with the Olympus system. K-1 and K-3II share the same technology but with K-1 partially compensating for moving subjects via software, not hardware. Read IR again.

The biggest advantage of mirrorless IMO is elimination of the mirror which is a major source of vibration. Short flangeback distance is nice but not essential to me. Making it too small actually renders it more difficult to hold.

On article Design, looks and desire: Olympus does it again (397 comments in total)

I don't find it to be attractive at all. I actually find it to cumbersome and pretentious. I don't want a camera to attract attention - whether they are good or bad.

webber15: DPR...stop with the equivalence b.s....I'm pretty sure ya never used to do this 4-5 years ago,,comparing everything to full frame...I simply couldn't care less...

Dave...

Equivalence is not new to many of us but I believe it is important to state that. It is a common platform for comparison. It is a standard reference by which lenses across formats can be compared. I am familiar with APS and m43 but not much on 1" or 645. Not wanting to have it is a little snobbish imo.

I am probably in the minority here. The pictures are unique but not very appealing to me. #5 & #9 are pattern but neither attractive nor interesting.

rtogog: Samyang should offer fl 200 mm 2.8 macro lens. Not this lens, otherwise this lenses performs better than similar lens on the market today.

I'd seriously consider a 200 mm macro, but not this 100 mm.

Link | Posted on Apr 3, 2015 at 00:59 UTC

What makes it stand out among other great 100-ish macro lenses already on the market?

On article CP+ 2015: Hands-on with new Pentax K-S2 (171 comments in total)

I was intrigued by K-S1 but did pull trigger because no WR. K-S2 is exactly what I am looking for. This will replace my K-01. Time will tell if it can replace my K-5 IIs.

Essentially mimicking the lens in our eyes. Instead of moving lens elements to focus, the focal length of an element changes. Implementation represents a significant challenge.

If it had WR, I'd buy it in a heart beat as replacement for K-5 IIs and K-01.

I prefer to see a 16-32.

I almost click the "Buy" button for a K-5IIs but held off the upgrade from a K-5. Glad I did. I have little reservation not only from the specs but from experience. All of the dslrs from Ds to K-5II have been class leading. The price is even a few hundreds lower than the price I paid for my K-5 3 years ago.
