想請教大家：
小女子1年前買了pentax 330rs，初時都察覺到影出黎的相實在不太清晰，但近來更發覺晒出來的相片還大不如前（在電腦看時也看得出），我已經用2048 x 1536影，但仍看得出很多微粒及好似加了soft的效果矇矇的，想請問這樣的問題是否証明它已經年紀老化(1年行貨，影了三千多張相)，還是鏡片的問題?(我並沒有跌過)。
像這樣的問題可以拿回去pentax廠維修嗎(雖然不知保養期是否過了)?
因為本身已經不是太好，現在還要差一截，實在很傷心~~
希望得到大家的幫忙，謝謝!!

照正常1年機齡不會是這樣的。你可以試下調較ISO值為100，不要設為自動，這樣試下拍出來的照片有沒有好些。

Are there any samples which we can see? It is difficult to determine without looking at the actual samples. You might check out these 330 samples for comparsion although I do not know if RS is much different.

Lenses do not degrade that fast. Good lenses last for more than 20 years. There are things you can do before you send it to the service centre. Quite often poor results is due to human error.
1) Keep the front element of the lens clean, but don't overdo it. You can use "Lenspen" & a hand blower for the job.
2) Always shoot at the highest resolution & the finest jpeg setting (lowest compression). Resize them on PC with Photoshop later, but never re-save jpeg more than once. You can save them in tiff format before any post-processing if you must.
3) Use tripod, mini-tripod or at least some sort of support to minimize camera shake as much as you can. The difference could be huge but often overlooked.
4) Avoid flash or direct sunlight, opt for diffused available. For instance, you can place the subject in shaded areas during the sunny day, or shooting on overcast day will help.
5) Make sure you let the camera to focus on the "contrasty" part of the subject, and then recompose.

PS: Be aware that the pictures appears slightly soft on computer monitors are perfectly acceptable (72dpi). They will look sharp once printed (200-360dpi). Moreover, you can always sharpen them if you like, but oversharpened pictures are no turning back.

多謝兩位的回答

其實我都深信鏡片不會一年就出現這個現像，但可惜實際看出的事實就是這樣的差了，不單止在電腦preview晒出來亦是一樣。比較以前新買時及現在影的setting、pixel等大都是一樣，而且由始至終大多數都用auto mode，所以應該可以撇除setting的問題。
多提的是：我部相機的LCD看時很光，平時就像在暴光下看相一樣，不知是否有關，所以平時preview後很難辦別出究竟相片是否夠光還是暴光，因為LCD實在太光。

你可以試下關掉LCD來拍攝，看看情況是怎樣？

It is normal that the LCD appears brighter than the actual picture taken.

可能是鏡頭移了位, 小弟見過這情況數次, 如果過了保用期, 買過部新機啦, 330RS 整番都唔值錢, 又唔知幾時再壞.

咁慘...鏡頭移o左位~~
雖然我都知整返都唔值錢，但係淨係買o左一年又買過部又好似有點兒浪費，因為買了部新後呢部又會被冷藏嘛!
但如果真係要整的話係咪有得整呢?(因為屋企仲有部kodak443既傻瓜機)
所以暫時唔想再買第三部住....
多謝各位既解答!!
