Sony alpha 350 - photographs not sharp enough
« on: April 02, 2009, 09:43:05 PM »
Hi - i have just bought a Sony a350 to use with my Minolta lenses from my old faithful Minolta 7000i set up.

I have just taken the camera outside just to try out my new toy - but the results  - well are more than disappointing. With a 28-100  f5.6 Minolta zoom lens left on Auto. I haven't tried my 75-300 lens yet. I have taken about 30 pictures and I'm not happy with any of them. The photographs are not sharp enough - seem very soft, Feel disappointed with the results from a brand new camera. I haven't adjusted any settings as i don't want to make it any worse.

Can anyone offer some simple solutions - best settings i should be using to produce some nice sharp pics which is why i bought the camera.

Please someone help. I do have many years of taking good sharp photographs,I'm not bragging honest - completed several city and guilds courses and gained distinctions with my faithful Minolta 7000i film camera on manual. 
This is my first Digital SLR, but have used on couple of canon D SLR in the past with results i would put on the wall.


Getting more and more depressed as i have many plans for this camera, so Yes I'm off to read the manual again. and again.

many thanks.

Hi,
Noticed you do not have any replies yet so I thought I would reply.
I have the similar A200 without the liveview etc but basically very similar to yours.

I mainly use my old Minolta lenses "70-210 beercan f4 and 28-105 Sigma".

I have had similar trouble with what I class as poor pics being produced by the camera.


I have come to the conclusion that the higher resolution that these high quality cameras have requires a user to work that bit harder than point & shoot users to achieve nice photos.

Try the camera in Aperture priority and step the lens down from the f5.6 to around f8 as that is usually where the sweet spot is on the older lenses.

Is the camera capturing at it's maximum image quality?

It is not hard to fool the meters on these modern cameras and with the images being blown up massively on your pc screen rather than a 10x8 print hung on a wall any image problems are made worse.

Why not try to use your experience in the photography field and stick it on manual and shoot away you have nothing to lose!

Sorry I can't be more help!

Dave

Thanks for your input, i will try what you have said and see what results i get. I have left all the settings as they were so  its set on 14mp, 3;2,fine quality..... just to list afew....
Its certainly not going to beat me without a fight.!! back to the manual again.

If those photos at the bottom of your reply are what you have taken with your sony, they look much better than mine.!!

cheers

Yes they were taken with the Sony.

In the camera menu you will find a setting to sharpen images.  But, if you shoot in raw format all of the pictures will look soft unless you apply a lot of sharpening, in the adobe camera raw plugin photos need %140 sharpening!

It's nothing to worry about, just sharpen the pictures after transfer to your pc or boost the shaprpness in the menu.

I would suggest not setting the camera to automatically sharpen pictures and would only use it sparingly in post processing and only at the last stage of processing.  The image not being sharp enough is normally down to either too much movement of the camera relative to the shutter speed, incorrect focusing point or quality of the lenses.  I know that I have some great lenses which helps but I hardly ever apply sharpening to my pictures.

This might be silliest question you might get to read around, but as this thread is related to sharp issues, I would like to know how does it work in the DSLR's telephoto lenses... We bought a 350 a while ago, however, I'm totally new to DSLR's, and when taking pictures and seeing throu the preview option on the camera, they look nice, when I zoom in on them in the camera to see more "details" on the picture, they come out blur, now, I'm not sure if it is something related to a bad posture while holding the camera and the lens, is it that I'm not focusing well on the object, or is it just that I'm demanding too much of the lenss... The lens in question is DT 55-200mm F4-5.6

Any help would be deeply appreciated! :)

Keane could be a number of things but just a guess are these taken zoomed all the way in or out. The kit lenses and a lot of zooms tend to be sharper in the middle of the range then at full zoom out or in.

That might be it... I'll try playing a little bit more with it to see how does it go!

Another thing to consider is that to eliminate camera shake, the shutter speed needs to be a minimum of 1/100 sec for the equivalent focal length.
i.e if you are using the 300mm range of your lens, you need to be using a shutter speed of a minimum of 1/300 sec.

Another thing is that most lenses are not at their sharpest when set to their maximum aperture, so in the case of the 70-300, f/5.6.
Try setting the aperture to f/8 and see how the shots look then.

I have no complaints with the picture quality using the lenses supplied with the Camera I've also purchased a Sigme 150/300 telephoto which gives excellent results. I'm going to the F1 GP in Abu Dhabi in November and will be putting the power drive, burst shooting to maximum use :-). The GPS add-on is also very useful and locates where you take photos very well.
Please forgive any spelling mistakes I have suffered a stroke an have to type one handed.

Thank you very much, that clears the views for me ;) It's kind of overwhelming for me to use this camera, as I'm totally lost with the lenses and all that stuff, I'll keep in mind your tip for the shutter, and I'll do the thing with the F numbers as well to see how does it goes... thanks again for the kind reply Rob, and to you all :)

I find when photos are soft I am too close to the subject.  You have only just brought this camera so you need time to see what it can do.  As you have said you need to read and re-read the manual and then go outside with the manual and practise as much as you can.  Use the manual setting and learn.
If you see this, you know its from me!
