FT, 我比较变态， BLADE 一两个星期磨一次。我喜欢这个草切特别整齐。
切不整齐把草叶子打烂容易感染霉菌。经常磨就 15 分钟搞定。
amazon 上有个 ACCUSHARP garden sharper 便宜又好用。
我以前还贴过教程的。
这个 blade 一两个月应该磨一次的。 |

发帖数: 2368 | 3 这个贴主说的清清楚楚只比了85L at 1.2对85G at 1.4,
到你这里就成了85L也用的是1.4了。
问：* I think it would be a bit more informative to test both at
f1.4, to see actual differences in same circumstances.
答：In the case of the 85L's image quality, there's nothing really
it lacks against the 85G when it's wide open at f/1.2. It's even a
bit sharper in the center if you look close enough. The two lenses
do have slight differences (at max aperture) but these will most
definitely not show up when doing anything other than a scient... 阅读全帖 |

新P老P双P对决: Panasonic 14mm f/2.5 on the GH2 and the Pentax 21mm f/3.2 on the K-5
虽然是山寨版对决, 但是还是挺认真的: tripod, self-timer, aperture priority autoexposure, shot in triplicate, processed with default Lightroom 3.3 sharpening and NR plus
default Nik Output Sharpening which maximizes detail but also increases noise and artifact
对决结果总结:
1. 新P老P饼干头锐度相当, 无论是中心还是边角
2. 新P饼干头焦外胜出! 油润, 德味!! XD

发帖数: 2318 | 11 My impressions are from sample photos of the two.
The thing is even for portraits (which the 24-70 should excel), feel that 70
-200 f4L captures sharper images, guess b/c 24-70 is a quite aged model? Or
b/c it doesn't have IS?
Though the 70-200 will need more space to take portraits. |

For indoor, set the parameters as - Tv, 1/1600S, ISO 200, f1.4, 45 degree

results (even the viewfinder indicates way underexposure). Good things about
these settings:
1. High shutter speed to capture the constantly moving subject

I just got a second generation copy. Before I used it I thought
it's junk, but it's surprisingly decent. Good build quality,
typical minolta color, albeit a strange range on the APS. I
think it's noticeably sharper than the 35-70 f/4. |

I used on my D7K, it is a good lens, but kind of old as many people said,
hard to compare to the new lens in terms of sharpness, like 16-35 and 24-70.
I think the 17-55 should be sharper and better on my DX.
But I bought it new at high price 3 months ago. selling it now will loss too
much, I guess I will keep it for a while. |

50/1.8D and 35-80.
35/1.8G large distortion but sharper.
35/2.0D less distortion + FX, but not as sharp
50/1.8D almost distortion free, want to keep.
50/1.4D large aperture
50/1.8G sharp, but relative large distortions
50/1,4G - do not want it for its distortions too large for 50mm. |

The blades are curved to create a circular image at all aperture settings,

In case you haven't figured it out, the Samyang is on the left, L glass on
the right. As you can see, I think the Samyang stacks up really nicely to
the L ... I find it sharper in the center than the L, but it does expose a
bit darker. Colors are a tad bit richer with the Samyang, and I think
contrast is also better in the cheaper lens. Put these two in bright light
situations and I think you'd have a very difficult time distinguishing one

"The D800E reproduces the texture of the stone pavement and twigs with
higher resolution than the D800. It allows sharper rendering with depth. "
"With the D800E, moiré and false color may be noticeable when there are
repetitive and fine patterns on a subject such as kimono fabric. To avoid
this, it is necessary to take measures, for example, changing the focusing
point or shooting distance." |

发帖数: 33224 | 34 这里还有一段：
Stopping aperture down increases depth of fi eld, making the
foreground and background sharper. Stop aperture down
too far, however, and diff raction will actually cause the image
to lose defi nition. The eff ects of diff raction are partly infl uenced
by the size of the pixels in the camera image sensor,
but with the D800/D800E’s high resolution the eff ects generally
become noticeable around f/11. When you need more
depth of fi eld, don’t just immediately stop the lens all the way

As expected, stupid-high ISOs like ISO 25,600 work, but look crummy. As expected, they're soft and smeary. They look exactly like ISO 3,200 from point-and-shoots: usable, but soft and smeared in firmware to hide the noise. In other words, with the right post-processing software, you'll get the same results and can get the same stupid-high ISOs from the older cameras by push-processing.

The Fuji X-Pro1's image quality and handling are astounding. AF and overall
speed is twice as fast as the X100, and the magic sensor, which plays tricks
to eliminate color moiré problems so it can dispense with the anti-
aliasing filter, are astoundingly sharp —sharper pixel-to-pixel than
anything from a DSLR and about the same —maybe better than the LEICA M9. |

Sonnar design lenses are faster than Tele-tessar, they provide very smooth
bokeh and are usually sharper than Tele-Tessar wide open
Planar design lenses are the fastest, sharp wide open, they provide the best
microcontrast and 3D, their bokeh can be "busy" especially with the
highlights. |
