The A12 50mm GR Lens has a focal length of 50 mm. Part of its appeal is that it gives a natural visual field with an angle of view nearly the same as the human eye. The 50 mm focal length is one of the most basic for candid photography. Compared to a wide-angle lens, a suitable distance is maintained from the subject, and the photographer is able to chat with the subject and elicit natural expressions to capture the person in a candid way without undue attention being paid to the camera. GR LENS A12 50 mm is also a macro lens. The photographer can enjoy close-up photography to a maximum magnification of 1/2x and, from a wide open aperture setting, obtain images with excellent sharpness and high contrast and resolution to the edge.
From the Manufacturer
The Ricoh A12 50mm f/2.5 Macro GR lens uses a 23.6 x 15.7mm (APS-C size) CMOS sensor with approximately 12.3 megapixels. In combination with image processing engine GR ENGINE III, it achieves high-image-quality photography with high definition, low noise, and smooth tonal gradations. A newly-developed GR Lens with an 8-group, 9-element configuration (aspherical lens: 1 element, two surfaces) is featured. Representing a further advancement in the GR tradition of high image quality, the lens thoroughly corrects for various types of aberrations. Despite the compact size, it is also a full-fledged macro lens with a floating lens structure. At shooting distances from infinity down to the 1/2x maximum magnification macro range, it achieves strong imaging power all the way to the edge of the frame. In addition, the low level of vignetting means that the photographer can enjoy rich and genuine bokeh effects. The manual focus ring is perfect for use in macro photography as it makes highly precise focusing possible. It can also be used to make fine manual adjustments to the focus after autofocus is done.

This particular lens is the standard and ubiquitous 50mm lens found on most starter (D)SLR cameras around the world. If you truly want to learn how to take good photography, a 50mm lens is the way to go. No uber-zooms, no wide angle issues - just straight photography as it was meant to be taken. Add to that a great macro feature and you can really take some amazing photos. The MP (12.3) on this lens isn't exactly first class any longer - but still very respectable for the average photography. Unless you plan on blowing the picture up to wall-size, you should be fine. And while this lens is fairly expensive (comparable to most DSLR lens that fit on Nikon, Canon, etc), it contains not only the lens, but also the CMOS chip that captures the photo - something that DSLR lens lack (as the camera body holds that chip on most DSLR cameras).
Pros: near DSLR like quality photos; respectable megapixels; excellent macro; fully enclosed body to prevent damage/dust
Cons: cost; sliding on/off camera body sometimes a pain; if/when something finally finds a way inside the lens, no way to remove it
Overall, this is a fine lens for the money and a great way to take photography - 50mm is the most versitile lens out there, in my humble opinion. Ricoh gives the average photography an excellent means of having near DSLR like capabilities in what amounts to the size and weight of an advanced point-and-shoot camera. Whether you are on the go or simply don't want to lug around a suitcase full of camera accessories, the Ricoh camera has you covered.
NOTE: when updating this particular camera's firmware, remember that each lens you own must be individually updated, since each lens contains its own processor. Many people update the camera body (as you would on most DSLR cameras), but forget that each lens likely has an update as well. This could alleviate some issues you may experience with your lens.
Why you should buy the the GXR -
- 100% customizable interface. there is absolutely no need to dive into the menus.
- everything is at the "top level" meaning there is instant control - just spin the knob or push the button. There's no "hold this button down then turn this" For example: I shoot in aperture priority. here are the commands that are directly accessible without any need to hold down any button or dive into menus:
3) exposure compensation
4) switch to Manual focus
5) enlarge image (focusing aid)
6) focus assist (peaking)
There are 5 additional, easily accessible and completely customizable functions that are just 1 button press away.
- snap focus mode with depth of field gauge. This is amazing, highly useful for street photography, and taking photos of fast-moving kids. there are 2 ways to do this:
1) when the camera is in AF mode, you can make it so that if the shutter button is fully pressed in 1 motion, the camera will focus at a pre-determined and user-adjustable distance (i.e. 2-meters). You can change this distance with 1 button press. if you use 1/2 press shutter, it is AF as usual.
2) when you are in snap focus or manual focus mode, there is a depth of field gauge that tells you the focus point and the DOF around that focus point.
- great LCD screen at 920k dots
- magnesium alloy build. the build quality is superb.
- you can hold the camera in 1 hand and operate almost all the controls. Also, the back of the camera has a large area where the thumb can rest and not accidentally touch any other button.
- the mode dial locks. This prevents accidentally changing the shooting mode.
Why you should get this lens module -
- Very sharp lens
- very versatile - 50mm standard lens, and also a macro lens
- the focus is good. The older firmware was not as good. The latest firmware is much better, and focus is much improved.
- the sensor is outstanding. clean to ISO 800, and ISO 1600 needs just a touch of NR in lightroom 3. the colors are fantastic and the image has a great look to it.
- one issue that DP review points out is that the raw file output is a bit soft - that's just how the processing is. It sharpens up perfectly with a bit of sharpening in LR3 - this reminds me of the files from the canon 5D. The jpg files are sharp and contrasty.
Now, here's a thought. I never understood why people bought the GXR until now:
1) the GXR balances sensor size to deliver a great shooting experience in a small form factor. want a large zoom? ok, get the 28-300 module. It's got a small sensor to keep the overall size small. If you want a 28-300 lens on full frame, buy the Canon 5D2 and 28-300 L for about $6000. You want uncompromising image quality? ok, get the 50mm or 28mm module w/ APSC module. The A12 APSC sensor is superb. clean to ISO 800. 1600 needs just a touch of NR in Lightroom.
2) why would the majority of people really need more than ISO 1600 and 12MP? this sensor and lens setup on the A12 modules is so good, I don't think anyone would need to update. i'll take the superior user interface any day.
Who should NOT get the GXR?
1) Sports photographers who need long, fast zoom lenses to shoot from the sidelines
2) night wedding photographers needing ISO 3200 and a 70-200 2.8 zoom
3) gear heads wanting to buy 12 lenses at 1,000 each, then wind up using just 2 of those.
4) people who need long tele lenses (i.e. bird photographers or animal photographers) or ultrawide lenses.
if you are in one of these groups, the GXR would not be a good 1 system camera, but would be a great 2nd system camera.
Now that the M mount is coming out, it's just getting better.
