User8606253983: Looking good, but outdated sensor. When will we get new sensors on m43. Been on 16 mp a while now. Would like my next om-d to have a few more pixels if possible.

mmmm 7dmk2 nice cam. i hear it nails every shot (that isn't user error) with perfect AF. also the sensor, I've read, is 20% improved over last model and usable for astrophotography. it's true the m43 still have some AF issues - but until I use the G7 I can't totally discount it.

WS,

G7 benefits: Portability/size (what good is a camera if it isn't with you), face detect, 4K video...assuming IQ and AF is good enough on the G7.

The T6s will be kept for corporate shoots...but I wish I could replace it with the G7. :)

outdated...meaning it isn't the same sensor as used in the GH4 (I believe). Also additional MP has the benefit of post processing cropping which is useful in many situations. But all in all yes 16MP is plenty to do a lot of things with. More MP is welcome though. Lately I've been shooting with the 24MP T6s and I appreciate the additional MP. I'm hoping the G7 can replace it or at least be a second camera.

nutraman: in the second image, how could both shots be 1/100s and F8? One shot was at ISO100 and the other at ISO3200... so the incorrect label should have a shutter speed 5 stops different.

ok, got it, thanks for the reply.

there are newer sensors around the corner. Panny holds them back on anything not named GH5. Panny hopes to have a 33mp sensor and 8K video for the 2020 Olympics. for today though we have this 16mp outdated sensor. but I'm betting Panny's image processing has improved.

Peter K Burian: I got to shoot for a half hour with this new G7 thanks to Panasonic Canada. Very impressive. Super fast autofocus even in a dark interior. AND 4K video. Also, a 30 frame per second drive (using 4K) that provides 8 megapixel still photos. AND superb image quality at low ISO, Surprisingly nice at ISO 3200.

see photos at https://picasaweb.google.com/110698711952841559844/20150520 (These JPEGs were made using preliminary software so I cannot post high res photos. These were SIGNIFICANTLY downsized.)

Peter I looked up your name on google...I love the lighting and color grading of your nature images - wonderful! How's the tracking AF on the G7 in stills and move?

On Canon announces 50mm F1.8 STM lens article (310 comments in total)
In reply to:

Togglebolt: 7 blades, sharpened properly can produce a sharp image but the difficulty in disassembling this lens and then to remove the aperture blades to sharpen would be a deal breaker for me. Never mind trying to put them all back together!! Of course if they come pre-sharpened like Nikon's aperture blades, then you can get at least 5K shots before needing sharpening. It's a shame these apertures get dull so easy. I have a closet full of disassembled lenses with dull apertures, such a shame to see all that nice glass not being used. I guess thats how Canon gets everyone to buy new lenses, ship them dull, make them difficult to sharpen and people just toss them & buy a new one, just like a shaving razor!

in a pinch I take off my lens and use my fingers in a circular lens-like shape, creating a 50mm f1.0 equivalent.

In reply to:

thk0: "There are three factors that affect how much light is available for your sensor to capture: your shutter speed, the size of your aperture (not f-number) and the size of your sensor."

Yes, f-number. If you use the physical aperture size, then the sensor size does not matter (assuming the same sensor coverage of the light circle). The amount of light passing through the lens, and hence "available for your sensor", only depends on the area of the entrance pupil, transmission efficiency and the duration of the exposure. If you use f-number, then the physical aperture scales with the sensor size and sensor size becomes part of the equation.

(edits for typos)

oh yeah, well I shoot without a lens. ;)

thank you dxo. I appreciate this information. Not everyone uses MF so a score for autofocus would have also been appreciated as sharpness is useless without fast, accurate AF.

oh and can you include a shot in the 'JPEG Test' section with the NR OFF and WARM OFF? Thanks!

On Olympus PEN Lite E-PL5 & PEN Mini E-PM2 preview (152 comments in total)

Mr Butler and dpreview crew, on the JPG image testing could you add 1 or 2 test shots with "warm color" off? I leave warm color OFF always on my epm1 and I think many people do too or many would be interested to see a test shot with warm off on the epm2 and epl5. Thanks much.

dpreview editors - a very minor error on page 28, which states:

"As you can see above, instances of moiré in the D800E are also present - to an admittedly lesser degree - in the D800."

the cameras should be switched:

i'm guessing these lenses could be compatible (and focus quickly) with canon's new PDAF mirrorless system - either directly or through an adapter. they were released beforehand to give the mirrorless system more 'punch' and show canons user base some level and interoperability between systems.

...just a guess.
