On Using third-party lenses on Sony Cyber-shot a7 / a7R article (490 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.

On Olympus OM-D E-M1 Review preview (2142 comments in total)
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 Nikon Df combines classic design with modern technology article (313 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 Sony Alpha A7 / A7R preview (2381 comments in total)
In reply to:

Photographer 1: I had the opportunity to see the new Sony Alpha 7R at an event at B & H Photo in NYC last night. The entire Sony technical team was their to demonstrate the camera. Frankly, the camera is a game changer. To have the ability to get a full frame camera in such a small package is amazing. I watched another photographer ask if their Canon lens would work on the A7R and the response was yes. I did a double take. They took the Canon lens and a Metabones adapter and placed it on the A7R. The results were profound with the Canon lens fully operational. Looking at the new Sony FF lenses it is clear with a Prime 35mm and 55mm they are targeting the avid shooters. No question it is a bold move for Sony, but after seeing and playing with the A7R there is no question I will buy one because this is a camera of the future.

I am a little confused here. Are you very sure that the Canon lenses were fully operational with A7R via Metabone adapter? Could you change the aperture settings of the Canon lenses via the A7R body and expose it rightly in aperture preferred mode? Could you expose rightly in the shutter preferred mode? If not, then you can't claim that Canon lenses were fully operational with A7R body. Would you please kindly update

On Canon EOS M Preview preview (544 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 First Impressions Review: Using the Canon PowerShot G16 article (351 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 Canon EOS 100D/Rebel SL1 Review preview (50 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 More pictures leak of purported Olympus PEN 'E-P5' article (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 Just Posted: Canon EOS 6D In-depth Review article (530 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?

On Preview:panasonicdmcgx1 (318 comments in total)

It is really puzzling to me why Panasonic fails to understand the aspirations and desires of many pros as well as enthusiasts when they bundle lenses with their ILC cameras. Recently they have completely stopped to bundle Lumix 20mm F1.7, which is a superb lens. In fact one can choose Micro4/3 only to use this lens on a second camera that can easily slip inside his overcoat pocket. GF3 was bundled with 14mm, logic Panasonic gave - smallest and lightest ILC. Fine, I can understand that. But is it wrong to offer another bundle with the 20mm? Will it be too expensive? A little may be, but many are eager to see the 20mm 1.7 to be bundled with the new GX-1 at least.

If Panasonic fails to do this, many will opt for a 3rd gen Olympus Pen cameras & add the Lumix 20mm to it. Choice is more flexible with the 3 Pens (we get the Zuiko bundled zoom as well). A more flexible & attractive choice I guess and the Zuiko zoom is not bad.

I hope Panasonic will not do the same mistake again with GX-1.
