Graphic high-ISO images! .Phase II evaluation Sony A900.

<P> Sony's high-ISO: most likely controversial topic </ P> <P> in the last issue of the trial, we did not go into A900's high ISO image problem, the reason we in the end has also been explained on .. .Considering this is the highest number of pixels, but also the highest pixel density full frame digital SLR 135 specifications. .We have to treat it more carefully: the face of imaging products in the technical indicators of progress, as the reviewers should be more positive attitude to look at it, which itself is also an encouragement to those who forge ahead. .</ P> <P align=center> <center> </ center> of the picture using Tamron SP AF 17-50mm F/2.8 XR Di II LD lens photography </ P> <P> Based on this idea, we use .Sony A900 specially filmed some of the traditional view that the poor performance of Sony's Alpha DSLR will be the scene: especially at night, the fainter still life under fluorescent and incandescent light shooting. .</ P> <P align=center> the picture using Tamron SP AF 17-50mm F/2.8 XR Di II LD lens photography </ P> <P align=center> we will use the A900 fitted with 50/1.7 lens .completion of filming, because the small size of the lens to capture the more subtle, and we can have full confidence in the fuselage A900 AF drive capacity </ P> <P align=left> capture this part of the indoor use of still life is a second-hand prices .800-1000 yuan only old AF50mm/1.7 lens, this lens is to avoid the use of high-end imaging to bring some help. .</ P> <P align=center> focal length 50mm F3.2 aperture shutter speed 1/40s ISO320 noise reduction Normal </ P> <P align=center> high resolution images for large size of the output is good, but .High pixel density is the current distrust of many enthusiasts </ P> <P> then we will use the A900 to shoot still life studio, the interception of A900 test images is mainly used for high-ISO noise reduction performance. .Then the A900's high ISO, the performance under indoor light how it, or let everyone see Figure talk. .</ P> <P>.
