Bag for Nikon CX 70-300mm f/4.5-5.6

Camera bags are very personal things. A bag that works well for me, might be totally wrong for someone else.

I like sling camera bags. The kind which you wear diagonally, and slip under the right arm for quick access to the contents.

Since getting the Nikon CX 70-300mm lens (my review), I have been looking for a sling bag for it. I was looking for a bag into which I could slip the lens, mounted to a camera, and with the hood mounted, ready for use. However, not many bags are large enough.

One bag which does fit, though, is the Tamrac Velocity 7x. The bag comes with two internal dividers, which can be placed wherever you want with velcro:

Sensor size is the new megapixel race

The camera industry is in a crisis. People have more or less stopped buying basic compact cameras, since mobile phones take good enough pictures anyway. Also DSLRs are seeing less sales.

There are two areas which still see good sales: Premium compacts and mirrorless cameras.

Panasonic used to be king of the premium compact line, with the Lumix LX7, and the Leica rebranded version. However, Sony raised the bar significantly with the RX100 series of cameras with a larger 1 inch sensor.

Panasonic's answer was the Lumix LX100, with an even larger sensor, however, now the camera is getting worringly larger than the predecessor. Also Canon wants to take part in this segment, with their Canon G7 X, also sporting a 1 inch sensor. Both of these cameras have significant issues, though: The Lumix camera lacks an articulated LCD screen, and the Canon lacks an EVF.

Nikon 30-110mm f/3.8-5.6 review

All camera systems have a cheap tele zoom lens available. Here are two such lenses, the Lumix G 45-200mm f/4-5.6 for Micro Four Thirds, and the Nikon 1 30-110mm f/3.8-5.6 for the Nikon 1 system:

The Nikon lens is seen here in a glossy orange finish. I guess it could have been worse, it could have been pink. Yes, this lens also exists in pink!

Electronic shutter readout speed

Many modern system cameras feature the electronic shutter option. This means that you can take pictures silently, without activating a mechanical curtain shutter. Rather, the exposure is started and stopped electronically.

The Nikon 1 series is pretty much built around electronic shutters. The basic J and S series of cameras do not even contain any mechanical shutter at all, you only have the electronic shutter option.

The downside of the electronic shutter is that not all the sensor is read at once. Rather, the sensor photosites exposures are started and stopped row for row, vertically. This process of starting and stopping the exposure, and then collecting the exposure data, can take around 1/10s to 1/100s, depending on the camera model.

The slower, the less useful the electronic shutter is, as you can risk rolling shutter effects, buildings appear to lean if you pan while photographing, for example.

Rolling shutter effects are not exclusive to digital cameras. Rather, they were present also with early film cameras. Here is a famous photo of a racing car taken in 1913 by Jacques Henri Lartigue using a 4x5 Speed Graphic camera:



The curtain shutter moves relatively slowly on this camera 100 years old camera, when compared with modern SLRs, which gives the distortion of the racing car. The distortion is especially visible in the wheels, which appear to be leaning forward. This rolling shutter effect was later copied by cartoonists when they wanted to give the impression of speed.

High speed video, slow motion

Already from the start, Nikon 1 cameras have been able to record video at a 1200 frames per second rate, which is very fast. A normal video frame rate is 30 FPS, in NTSC countries, so you are able to record videos 40 times as fast.

This can be used to make interesting slow motion videos. In this example, I used a Nikon 1 J1 to record the mechanical shutter of the Lumix GM1 camera.

The newest Nikon 1 V3 camera also has the high speed video feature. It can record 1200 FPS, without audio, and in an unusual 416x144 pixel resolution. When the video recording is started, it lasts only for 3 seconds, so the timing of the start of the video is crucial.

Comparison of normal lenses, Nikon 18.5mm f/1.8 vs Leica 25mm f/1.4

Some decades ago, when film SLR cameras became popular, the 50mm lens was abundant. Due to the long register distance of SLR cameras, the 50mm lens was the shortest which could be designed cheaply with a large aperture, which is why it became so popular. It became the standard lens people bought with an SLR camera, the normal lens.

Nowadays, the kit zoom lens has become the normal lens, but the field of view corresponding to a traditional 50mm lens is still popular. So most manufacturers release a fast "normal lens" when they invest into a new lens mount. In this article, I will compare two normal lenses for two different systems, the Nikon 18.5mm f/1.8 for Nikon 1, and the Leica 25mm f/1.4 for Micro Four Thirds:

Lens	Nikon 18.5mm f/1.8	Leica 25mm f/1.4
Announced	Sep 13th, 2012	Jun 13th, 2011
System crop factor	2.7	2
Equivalent focal length	50mm	50mm
Maximum aperture	f/1.8	f/1.4
Equivalent max aperture, in terms of DoF	f/4.8	f/2.8
Weight	70g	200g
Diameter	56mm	63mm
Length	36mm	55mm
Filter thread	40.5mm	46mm
Minimum focus	0.20m	0.30m
Lens elements/groups	8/6	9/7
Hood included	No, HB-N104	Yes
Focus ring	No	Yes

Both correspond to 50mm field of view on a 135 film camera, and both are quite fast, with large maximum apertures:

Nikon 1 lens lineup

The Nikon 1 format is still fairly new, but they have managed to launch a respectable lens lineup already, covering most photographic needs. Here is an overview over the existing lenses that fit the Nikon 1 CX system.
