   Im excited about finding the battery problem with my sony a330 with AF Minolta lenses (and some Sonys)  was a bad charger! ! 5 years I moped about it killing its battery within minutes, and it was never getting charged! I'm now ready to photograph  places  - 2 gig micro sd card holds over 1000 images on "fine"-  what are  the fastest lenses available? my lenses start out at 4 - is this even an issue any longer? btw, ty for the add

Unless you are an Initiate in the Cult of Bokeh, 

fast lenses are simply a tool to deal with a lack 

of light on the scene, and at a sacrifice of useful

DoF. So, you have f/4 lenses and an older body 

that doesn't handle higher ISO all that well as to 

both noise and the limited high ISO typical of a

CCD sensor. Fast lenses will cost you lots more 

than a faster sensor ... IOW a newer body. Not 

to mention a better finder, twice the MP, video if 

you're ever so inclined, and more and more. OK, 

so I did mention the "not to mention" stuff. Just

sue me ! But thank me later ;-)

The A3X0 series were quite good mainly due to the CCD sensors which had superior IQ at lower (=reasonable) ISO. The jpeg engine wasn't great, though, so I would recommend using raw.

 

All in all it's still a competent picture maker. If you want some faster lenses, I recommend the SAM 35mm f1.8, 50mm f1.8 and 85mm f2.8. Optically, these are delightful lenses. The af and build quality are basic, which keeps the price down.

 

Regarding dof there are two types of photos: 1) photos with bokeh and 2) rubbish photos ;) Luckily, the lenses I mentioned have good bokeh.

    • I've been using this lens extensively without any sharpness issues. At long focal lengths, you'll have to factor in the need for a faster shutter speed (< 1/500-ish at 350mm) and other factors like atmospheric distortion, fog/dust haze, etc. All these factors contribute to a deterioration of image quality at longer focal lengths.
    • That's supposed to be a pretty good APS-C lens. Can you try it on a different camera just for the heck of it? Friend? Camera shop? The lens is noted for sharpness, so if you're having as much trouble as you say, you may want to look into a replacement or repair. 
    • Hi everyone, I’m reaching out to the community because I’m facing a persistent image quality issue with my Sony 70–350mm f/4.5–6.3 G OSS lens, and I’d like to know if this is normal behavior or if my copy is defective. Problem description: I’ve extensively compared the 70–350mm G OSS with my Sony 18–135mm f/3.5–5.6 OSS, using a Sony A6700, under controlled conditions: • Identical lighting and background • Same subject and position (LEGO figure, consistent framing) • Tripod or steady support • Manual focus or AF with center point • Same shutter speed (e.g., 1/200s), similar ISO (ISO 4000–6400), RAW + JPEG • OIS turned on (and also tested with OIS off) My observations: • At 135mm, the 70–350mm G OSS delivers softer, flatter images than the 18–135mm, even when stopped down. • At 350mm, the sharpness drops significantly – the center is soft, and textures (like LEGO tiles or fabric) appear blurred or smudged. • Contrast and micro-detail are noticeably inferior across all focal lengths. • The 18–135mm at 135mm (even cropped) retains better edge sharpness and detail definition. • Both JPEG and RAW files confirm the issue – this is not just JPEG processing or noise reduction. Question to the community: • Have others experienced similar softness with the 70–350mm? • Is it possible I have a decentered or optically misaligned copy? • Is there a known issue with OSS introducing softness at long focal lengths? I wanted to love this lens due to the range and portability, but currently it’s unusable for anything where image quality matters. I’m considering returning or sending it for service. Thanks in advance for any feedback or comparison results you can share.
