On article Using third-party lenses on the Sony a7 / a7R (519 comments in total)
In reply to:

abortabort: Two points that I think have been missed, not only here but in the A7 review as well:

1) Why do you set C1 or C2 as focus magnifier? C2 is clunky to get to (as you say) and C1 is too close to the shutter button. After extensive playing with different settings I now do not have a 'focus magnifier' button at all! You simply don't need it on the A7/R. Why? I shoot a variety of lens types on the A7, this includes native lenses, A-Mount lenses (LA-EA4), EF Mount lenses (with Metabones adapter), MD mount and m42 mount. Now because I shoot a number of different lenses which have differing capabilities in AF on the A7, from very good (native and A-Mount) to very poor (EF mount) to non-existent (MD and m42 etc) I wanted a configuration that worked for all lens types, rather than reconfiguring for manual and AF lenses every time.... TBC

Can you please give further details of your experience with Canon EF lenses with Meabones adapte. According to Metabones their markIII EF-E mount adapter is able to deliverelectronic aperture selection, EXIF data, image stabilization and lastly autofocus.

Can anyone else comment on that if you have that particular experience.

Thanks.

Aref

In reply to:

seri_art: It's the same size as my XSi and 10% heavier. What did it do with the should-have size advantage of the 4/3 sensor and lack of a mirror?

XSi is a consumer grade SLR without
1. Magnesium alloy body
2. Tilting & much higher resolution screen
3. Weather proofing
4. High speed burst till 9 frames/sec
5. Continuous focusing in full HD movies (XSi can take movie)
6. Much smaller form factor when coupled with MFT pancake lenses like Lumix 20mm F1.7. There more................
I really wonder why you wanted to compare XSi with EM-1.

On article Nikon Df combines classic design with modern technology (314 comments in total)

I think Nikon had to compromise to put a 16MP FX sensor to make it more compatible optically with the old generation lenses (both for resolution as well as to reduce the effect of angular incidence on the sensor micro-lenses at the periphery).

1/8000 sec shutter should have been included. There can't be any excuse not to include it in a 2700$ body.It is a wrong decision made by Nikon as they also did with the 1" sensor mirrorless cameras.

On article Canon EOS M hands-on preview (563 comments in total)

Hey Canon wake up. Please observe the mirrorless ILCs that are bursting around you. EOS M is a good camera for still shots, but not a great one. It is high time to come with EOS M II with -
1. Better sensor (like the 70D sensor with better focusing capability)
2. Tilting LCD, at least vertical tilting to get the advantage of 0.15m close
focusing ability of EFM 11-22mm in low angle shot and also for macro works
3. Electronic viewfinder either built in or add on
4. Better grip to hold the camera (it wanted slip of my hands several times)
5. The battery life is very poor. If the battery type could not be changed, then a
built in electronic viewfinder will enhance the battery life.

On article First Impressions Review: Using the Canon PowerShot G16 (354 comments in total)

I guess it is time for Canon to come up with a EOS M II with the 70D sensor, an articulated LCD and of course with an option of plug in electronic viewfinder. Removing the articulated LCD from G series was not a wise step.

On article Canon EOS 100D/Rebel SL1 Review (76 comments in total)

40mm 2.8 STM is a full frame lens and it become 64mm equivalent if we use it with EOS 100D. So you really cant use for street photography. It is really perplexing to me why Canon is not making any pancake lens for EFS, like M22mm F2 (equvalent to 35mm full frame) they made for EOS M. They can easily modify that lens to be used with 100D. The combined small form factor with any 24, 28 or 35mm equivalen pancake lens EFS will be a big selling boost for 100D and other Canon APC SLRs.

I think Canon should rethink in their lens line up strategy.

On article More pictures leak of purported Olympus PEN 'E-P5' (237 comments in total)
In reply to:

Mssimo: from 43rumors

A source told me that the new E-P5 has an improved 5 axis stabilization. Compared to the E-M5 this means that it has a new IS-Auto mode that automatically detects the camera’s movements.
And here are some more E-P5 specs:

- 16 Megapixel sensor (same as E-M5)
- TruePic VI image processing engine
- improved AF (compared to E-M5)
- improved 5 axis stabilization
- 5fps
- focus peaking
- Shutter 1/8000 sec
- built-in WiFi
- 1.04 million dot tilting touchscreen LCD (no more OLED!).

17mm, 45mm and 75mm Black lens rumor

My first camera was Olympus Pen EES-2, then Pen FT then all the way up to OM-4T. Just info for the readers, Pen-FT shutter speed was up to 1/500. It had side wise prism and had vertical running metal shutter (unbelievable for 1968) covering a smaller 18x24mm half frame. That is why they could sync all the way up to 1/500.

After film era I switched to Canon starting with G2, 30D then spanning till 5DII. I was not happy with noise of the early Oly sensors.
But the OM lenses were fabulous and still is. I regularly use them with Canon and OM-D. Specially the primes - 24mm F2.8, 35mm F2, 50mm F2 macro, 100mm F2 and 2.8. OM-D with OM Zuiko 50mm F2 macro and 100mm F2 produced spectacular results.

17mm, 45mm and 75mm Black lens rumor

Good specs. But I would prefer a buily in viefinder rather than the flash. I am a candid shooter. Most of the pictures now I take with OM-D and Lumix 20mm F1.7 lens. The combination I carry in a small sling bag. With E-P5 it will be more compact

On article Just Posted: Canon EOS 6D In-depth Review (531 comments in total)

I guess it is unfare to give 6D Silver award with 83% score while 5DIII got a gold with 82% score. Though both of them are full framers, but they belong to different price and user class. For enthusiasts GPS and WiFi is are quite attractive features, but paying extra for them may be heavy on their pockets. Very fast but cheaper SD cardsnowadays should be and advantage for an enthusiast's camera. On camera distortion correction is another reason for which I plan to swap my 5DII with 6D.

Can anyone update how a Panasonic 20mm F 1.7 performs on a Olympus Pen camera. It has a high uncorrected barrel distortion of >3%. Can Olympus Pens correct the distortion of JPEG and RAW files like Panasonic cameras?
