I took shots in both Aperature mode and Portrait mode. With both, the pictures were blurred if the subject (one of my pups) moved even the slightest bit, such as turned their head. Are these lenses not suitable for taking shots of a slowly moving subject or do I need to adjust the settings? |
The differences would first be in angle - you should have a bit of a wider angle on the 35mm, which can be nice. So, sit in one place with both lenses - put the 50mm on and look at a subject, then put the 35mm lens on and look at the exact same area - you should see a wider area/angle.
The 35mm is a higher quality lens, in general, but differences caused by quality alone sometimes take more time to see, especially as you're getting used to the lens.
Another difference might be closest focus distance - what is the closest you can be w/ the 35mm where it still has the ability to focus? That's really helpful to know.
For the blur question....when shooting at wide apertures, your depth of field is so tiny - so if the subject moves *out* of the field that is in focus, then they are in the blurry area (very easily, w/ slightest move). The other consideration/cause there is the light - if you are also shooting in tough light, your shutter may be too slow - so that could also be what's causing the blur (or, are you using your flash?)?

I need to do like you said and spend more time with it and play with the settings/modes. Unless you want to come visit and teach me all your tricks?  |
I'd check first re. the closest focus distance.
So, do you mean...does it give you the "I'm in focus" indication, but shutter never engages? Or, does it just never focus? I'm thinking if it locks a focus, but doesn't engage, then I wonder what your flash setting is...ie, is your camera set to flash, but the flash isn't ready...or...?
