Aspherical "V" Normal

[royalwolf10]

I would like some feed back on the two styles of lenses for my DSLR. I am using a normal Canon lenses that I had for my 35mm. I can identify a small amount of fringing and the occasional sun flare but other that what will the aspherical lenses do for me? I have access to one in a couple of weeks but would also like the feed back.

ALL YOU WOULD WANT TO KNOW ABOUT ASPHERICAL LENSES.

Thanks Haifidelity,

That was helpful. I have a related question if you don't mind. One of the number one concerns that I have is crispness or extreme clarity in my images. I have lost that with my Canon D Rebel. What can I do and is it really the lens's fault? It couldn't possible be any thing I do,...

The 300D probably WILL give you better (not more...) sharpness and clarity. Due to the lack of grain in the lower ISO setting and post processing capability (specially if you shoot in RAW mode), the sharpness and clarity can be startling. Remember, you can only get as much sharpness as your lens' resolution power allows, not more.

ROYALWOLF,

what type of lens are you using for your DRebel?

If you're using the same lens on the DRebel as on the film camera but the images aren't coming out as sharp as it used to with to film, you may need to post-process your digital images using USM to sharpen the images a little. You can try using the in-camera sharpening but if it still isn't sharp enough, you may have to use a photo editor. THe IR filter/shield that's placed infront of the sensor has an effect of "dulling" the images that reach the sensor.

PaceAce:
IR Filter? Are you talking about the AA filter? Please elaborate.

RoyalWolf:

Take into account that when film is developed and printed, typically at 4X6 size, you don't have the convience of viewing at 100% unless with a good loupe.

The convience of digital allows you to 'nit-pick' at 100%, making just about all of us more critical of lens performance.

I can look back at old 8X10 prints done on film and think "Crap, that was a real ****ty lens." when back in the day I probably thought it was sharp and brilliant.

I think alot of Photographers taking up Digital are now being able to pick apart a lens they once thought were excellent--for better or for worse.

Haifidelity, you are correct!!! most of the time I open a image at 100% pixel size for editing. once it goes back to a 8x10 or 5x7 it is fine. My level of self critiquing is far more harsh than any could ever hit me with.

I am using the standard low end Canon 28-80 and the 75-300. From the transparencies and prints from the transparencies the lenses appear to work fine for a few hundred $.

Royalwolf,

Getting lenses with Aspherical Elements will help reduce Lateral Chromatic Abberation, but it's not an end all to that. If you're using consumer line lenses, I would expect to be some CA in your photos, simply from the grade of glass and special characteristics that aren't there that are in the 'L' series.

Aspherical Elements, Lens Coating and Super UD/Fluorite Lenses typically found in the 'L' Series lenses combine to reduce Flare and CA.

I'm not saying you need 'L' lenses to take great shots, that's up to you, but it sure helps when you have the right tools.
