Novoflex Adapter to Mount Nikon Lenses on a Leica M Body Review

Novoflex Adapter to Mount Nikon Lenses on a Leica M Body

Novoflex built this slick little adapter so that you can take advantage of your vast collection of Nikkor lenses. It fits like a charm, and works well with Leica's in-camera metering systems. I used this on a Leica M6TTL as well as a Leica MP. There were no conflicts. I used a variety of lenses from the 13mm f/5.6 Nikkor AIS exotic ultra-wide to the 58mm f/1.2 Noct-Nikkor (head to head testing of the Noctilux by Leica with the Nikon high speed lens). No problems with mounting nor conflict issues. While I did mount my Fisheye-Nikkor 7.5mm f/5.6 lens on the M6 successfully, I did notice some image cutoff. Will test that again with the MP. I have no idea why that would happen. For the most part, this adapter is not a problem. Of course, the focusing cam is non-functional and focus should be via the manual method or using hyperfocal rules.

Panasonic G2 is a successor of G1, which is the first micro four third camera. G series focus on make the camera as small as possible without sacrificing image quality and control. G2 adds video recording and touch screen feature.
Panasonic G2 main specs
- 12 megapixel - four thirds sensor
- 3"' 460k resolution swivel and touch screen LCD
- 1,280 x 720 high-definition at 60fps
- Built-in Electronic viewfinder (1.44 million dots)
BODY DESIGN
Panasonic G2 weights 371 g / 13.09 oz body only, 593 g / 20.92 oz with battery, memory card and 14-42mm lens. It has dimension of 124 x 83.6 x 74 mm exclude protusion. Compared to regular DSLR camera, The package is significantly smaller and lightweight. Compare to advanced DSLR such as Canon 7D , G2 is approx. half the size and weight. As a result, it is more fun to carry around and it takes only a bit of room to store.
Like G1, Panasonic G2 has built-in electronic viewfinder which is helpful for composing photos, the rear 3' inch LCD is also very bright and nice to use. It can also swivel so you can compose a picture in unusual angle for example overhead or very low in the ground.
New in micro four third system, LCD screen is now equipped with touchscreen technology. You can touch the screen to select or change various settings and also you can touch the screen to set auto focus point.
Therefore, changing AF points in G2 is very fast. In regular DSLR camera, you might need to scroll around until you get AF point that you want. in G2, you just touch it. AF point could be also be enlarged or decreased for precision.
HANDLING
Panasonic G2 is nice to hold, thanks to the grip. It also has many dedicated buttons and switches. It has one main dial, camera mode dial, Release mode switch, Auto focus mode switch, metering switch, ISO button, WB button, Function button, AF/AE lock button, display button, delete button, live/lcd button, intelligent auto button, and video recording button.
As a result, control and handling is significantly better and faster than many entry level cameras where you need to dwell deep in the menu to change setting that you want.
IMAGE QUALITY
Image quality in low ISO setting is excellent. However, like all four thirds system camera, image in high ISO is not as good as regular DSLR camera that has APS-C sensor.
Image quality from ISO 100 to 800 is excellent. in ISO 1600, image starts to lose some details, sharpness and a bit of saturation. In ISO 3200, image starts to breakdown and 6400 is reserved only in emergency situation.
AUTO FOCUS PERFORMANCE
G2 is an very responsive camera. It shines in auto focus performance. AF speed is almost instantaneous whether in bright light or low light condition, I feel it can beat some beginner DSLR cameras. In G2, you can also touch the screen to set up AF point which is very convenient.
Auto focus tracking work well in slow moving subject, such as people walking, however, sometimes, it failed to track, especially fast or erratic movement. This is where the area G2 lacks compared to regular DSLR camera.
There are plenty to like about Panasonic G2
+ Small and lightweight relative to DSLR camera
+ Built-in high-res electronic viewfinder
+ Touch screen that allow you to change setting, set AF and flip image in playback
+ Swivel LCD screen help to compose photos in awkward angle
+ Fast Auto focus performance
+ Many dedicated buttons and switches
+ What you see is what you get (changing color balance, film mode shown in LCD)
+ Very good performance (responsive)
What I don't like about Panasonic G2
- Auto focus tracking is not reliable
- Image quality in ISO 1600 and above is not as good as regular DSLR
- Harder to achieve shallow depth of field (Defocus background)
- 1/2 to 1 second screen freeze after capturing photo
- Auto ISO is not very accurate and tend to stick with ISO 400
COMPETITORS
Samsung NX10 - Digital camera - prosumer - 14.6 Mpix - body only - supported memory: SD, SDHC - noble black
NX10 has bigger image sensor (APS-C) and higher-res (610k) AMOLED screen, however NX10 built-in viewfinder, body handling is not as good as Panasonic G2. G2 also slightly faster in auto focus performance.
Olympus PEN E-P2 12.3 MP Micro Four Thirds Interchangeable Lens Digital Camera with 14-42mm f/3.5-5.6 Zuiko Digital Zoom Lens and Electronic View Finder
Olympus E-P2 has a smaller design and more appropriate to be compared with Panasonic GF1 instead of G2. The main advantage E-P2 has is it has built-in image stabilization, however, it falls short in many areas such as slow auto focus especially in low light condition, low res LCD screen, and no built-in flash.
CONCLUSION
Panasonic G2 is the best flagship micro four thirds camera in 2010 with many new innovative technology such as touch screen LCD and full HD video recording. It is fun to use and carry around. However, G2 still has the same problem that has plague many four third system cameras which is image quality in high ISO setting. Despite it offers up to ISO 6400, but I recommend user to stick with ISO 800 or lower.
Subjective rating relative to mirrorless camera system 2010
Image Quality : 4/5 (with 14-42mm kit lens)
Features: 5/5
Performance: 5/5
Body / Handling: 5/5
Value for money: 3/5

Nikon 20mm f/2.8D AF Nikkor Lens for Nikon Digital SLR Cameras Review

Nikon 20mm f/2.8D AF Nikkor Lens for Nikon Digital SLR Cameras

The Nikon AF20mm f2.8 was designed as a "pro" wideangle lens back in the days when 20mm in autofocus was as wide as you could get. Originally introduced in 1989 it was the AF equivalent of the manual focus design of 1984 and uses the same optical formula as the MF. The subsequent addition of the D chip has changed nothing else. In it's day an AF 20mm was pretty radical and it was only superceeded in 1993 by wider primes as the pros sought wider and wider views. For most amateurs however 20mm on film will get you into the "superwide" range without breaking the bank. For digital shooters, dealing with the 1.5 magnification factor in Nikon D-SLRs, it becomes effectively 30mm, which is still wide enough for most situations.
Optically it delivers typical Nikon high color saturation and contrast, with distortions well controlled for it's focal length. While it is reasonably free from flare I strongly recommend the optional HB-4 lenshood designed for it and polarizing will be dificult for film shooters due to vignetting caused by the thick polarizing filter mounts of a "standard" polarizer. Digital shooters should not have this problem because the camera's sensor is only using the central portion of the projected circle - inside the area of vignetting.
Mechanically it is all metal and well constructed with an nice "solid" feel to it for an AF lens but those of us who still miss the old manual focus "tanks" will find the undamped focusing ring a little too "loose" when manually focused. As part of a planned outfit, it can form the wide angle anchor for a travel kit standardized on 62mm filters. Add Nikon's 28-105AF 3.5-4.5 and 70-210AF 4.5-5.6 and you have a lightweight kit for either film or digital SLR's
