1st outing with FA 50 f/1.4

After a month long searching for indoor portraits and debate in
choosing among FA 50 f/1.4, FA 35 f/2.0 and manual 50 mm lens, I
made the move with FA 50 f/1.4

Looking for portrait lens

Thoughts on external flash after FA 50 f/1.4

Portraits with DA 50-200 (why I want an external flash)

Here are few test shots, please comment if you want to see a bigger
size.

C&C are welcome. I will follow up with more thoughts on the lens.
The test shots come out with beautiful color to me and its AF is
faster than the kit's lens or the DA 50-200. The bokeh, narrow dof
and color are something to like about this lens.

I like the lens so far but there are some small surprises. I know it
is not the norm in pixel peeping but for new lens and especially with
the newbie me with a worried head, I did see in in 100% crop and many
of the colorful pictures come out quite soft. I have untrained eyes
for seeing what is normal. Also I really have a consistent tilt
clockwise with my K100D, all pictures need a slight adjustment and it
is quite daunting in fixing almost every pictures before I upload
them. I will seek advice in another thread on the tilted pictures from my
K100D.

Thanks,
Hin

Very contrasty photos! One suggestion. For the last photo and in the future when you shoot in the shadows/shade, you should pick the "Shade" White Balance Preset (The one just below the Daylight preset). It should get rid of that blue-gray cast.

Thanks everyone

Thank you everyone for the correction, comments and visits. Pete, I don't have a good understanding on the use of shade and cloud WB preset settings, thank you for the suggestion and I would definitely try it next time. Much thanks for the suggestion.

When I browse many of the pictures in Picasa, I zoom in to 100% crop size, I see pictures done in f/4.0 are not as sharp. Somewhat surprise to me though I find great color, contrast, great perspective from narrow DOF. Maybe narrow DOF causes some of my shots to be off focus as a farther distance. I would do more diligent looking in this photoset, all are welcome to see 'all sizes' to see the original.

Maybe I have untrained eyes to tell what is normal. I will pick a picture to seek advice and help with pixel peeping from you all later on.

Haha once you master the presets, you'll soon be wishing for a fine tuning option like in the K10D.

Sometimes lighting isn't always as simple as "Incandescent" or "Fluorescent" etc. Once you get different types of artifical lighting all at once...prepare to start ripping your hair out haha.

Please help me check on sharpness -- is this normal

I don't have trained eyes to see if my F50 f/1.4 test shots are sharp or not. I vaguely compare some indoor shots at f/2.0 with f/4.0 in DA 50-200. I don't have the test shots uploaded as those are really boring shots but the test shots seem show better sharpness from my DA 50-200. And that seems to dampen my excitement with the colorful photos from my FA 50 f/1.4.

Can I get help from forums to pixel peep at originals for the following to see if sharpness looks okay to you?

#1 sharpness check1


Original in 'all sizes' link

#2 sharpness check2

IMGP1322 on Flickr - Photo Sharing!

#3 sharpness check3

original in 'all sizes' link
IMGP1402 on Flickr - Photo Sharing!

#4 sharpness check4

IMGP1370 on Flickr - Photo Sharing!

All flickr page has the exif in 'more properties' link on sidebar on
right side. I really can't tell if they are sharp or not, I have
untrained eyes and lack experience. And I may have user faults with
narrow DOF, winds on flower shot, AWB for shady shots, and I suspect
the +1 sharpness setting in my K100D has negative side effects on NR.
All my shots are taken in 'bright mode' with +1 sharpness, average
meterring with multiple select AF point in center and defaults for
everything else.

Thanks,
Hin

Need help in checking sharpness

The problem that I may have is that I have a setting Flickr in dis-allowing original download from anyone to avoid image theft. For today, I have turned that feature off until later. I wonder if someone can help me look at the original to see if the softness in my test shots are normal. It is also likely due to narrow DOF and other reason. But I suspect back focusing. I am newbie with untrained eyes, need some help here

Again, thanks so much for the help. Here are the four links:

#2

original:

#4

Thanks a bunch in advance.

Very nice photos! Remember its not all about sharpness! Colour/contrast play a large role too!

Compare #10 in the first set of photos you posted to the 'sharpness check #3 photo'? Thats the difference between the wrong WB and right WB. Of course you had AWB so the camera metered on its own but always remember, if AWB lets you down, take another shot with the most appropriate WB preset!

I think all of your shots have come out great ... colour rendition is pretty damn nice indeed.
I am about to purchase the same lens and looking at your photos makes me glad I made the right choice.

And for the price ... you really can't go past the FA50 by the looks of those photos.

Nice photos. I am almost certain to be getting the same lens but I am just wondering why people on ebay would pay upto $200 on the manual version while you can get the autofocus one new for $199 with $25 rebate. Can someone comment on that?

I hope other can jump in with their assessment. I find that FA autofocus to be faster than that of my DA 18-55 and DA 50-200 and AF is important for me to take indoor shots with my kids, I can't afford that few seconds in looking for the focus trap spot with manual lens. All ebay prices seem very unreasonable to me for the A and manual lens for 50, that is my impression when I look.

Thanks,
Hin

Please help me check on softness

Still undecided about the softness of my FA 50 f/1.4

I did the original snapshots of comparing my FA 50 f/1.4 with similar shot from my DA 50-200. This is very unscientific as I don't have the experience and trained eyes to spot problems. but so far, I seem to see very many soft pictures at f/2.0 and even f/4.0 with my FA 50 f/1.4 though I love the color, contrast, great perspective and relatively faster AF on the lens. My #3 shot at 1/13 second shutter speed with my DA 50-200 seems crisper than #1 and #2 done with my FA 50 f/1.4. I may have user errors but in both daylight and indoor shooting, I continue to see very soft pictures at f/2.0. Original can be seen is the 'original' links that I provide below.

#1

Comments and feedbacks are very much appreciated. I have to decide in few days whether to ask for a return for the FA and I wonder if I am onto some not significant or whether what I am seeing is actually normal in my new FA 50 f/1.4.

Thanks,
Hin

The f/2.0 seems sharp to me, the 1.4 is a little softer, but I think that is to be expected. But I'm no expert so.....
