A few from a shoot yesterday

Nothing crazy here. Simple setup with 1 strobe and reflector. Yes I know its babies but I do a lot of these every year and sell many prints in the 20x30 range. I have included a normal and a zoom crop.

First Shot:
120 FA at f4


Second Shot:
45-85mm at f8 zoomed to 85mm


I also took pictures with my new 55 (tack sharp as far as I can tell) and the 75. I mainly used the 75 in low light so they did not turn out that well (didnt have a fast enough shutter speed). The images below were processed in LR3 with default settings. No sharpening applied just default.

Both look good, though due to magnification the 120mm looks better. But I'm wondering how much web images play tricks on us. Is the 45-85 at 85 really good in your opinion? (I've tended to use the zoom in the wider angles so far. Reports are that this is where it shines, but I can't confirm hat.)

Well as far as I can tell the 45-85mm has been great for me. For a zoom the only thing I can really compare to is my canon 24-105mm in this zoom range. This lens is way sharper than the canon.

You didn't clean off the eye pus for the first shot :-)
That's an amazing amount of detail. Have you tried 20x30 prints yet? Curious how they turned out compared to your Canon prints...mainly wondering if you'd notice a difference at that size vs. the 30x40" that the 645D is easily capable of...

I notice a difference when doing 20x30 prints....but this difference is mainly sharpness. Let me explain.

Normally I shoot with a 24-105, 50 f1.4 or 100mm f2.8 Macro. I usually shoot at f4-f8 and if I have some good window light I will shoot without a flash and use f2-f2.8

Out of all the Canon lenses I own, only 1 of them has given me sharpness close to what I have seen out of most of my Pentax shots and that is the 100mm macro. That lens is very sharp and gets me similar results. My 50 does an ok job, and my 24-105 is no where close.

Now for prints I see a difference using Epson Exhibition Fibre. With this paper I have printed a ton of 20x30 shots (and 24x36) at 2880dpi. Here I can see a clear difference mainly because this paper can really take the resolution. I can see a slight difference in Luster paper as well but its only noticeable when viewing the print 12 inches or less from your eye. Canvas and Rag papers I cannot see a difference until I print at 30x40. At 30x40 on any paper the 645D really shines.

One more thing to mention is cropping. I get many request for the 8x10 ratio with sizes as large as 24x30. This is where I love the 645D. Cropping is minimal with this ratio compared to a 4x6 ratio....so you have more pixels to work with.

My shooting style has always been to backup just a little to make room for people who want 5x7 or 8x10 ratio print sizes. I still have to do the same thing with the Pentax because people still love there 4x6 small prints.

I almost forgot to mention this. I did a few shots using ISO 800 and 1600. They weren't bad at all. Obviously the Canon really shines here but one thing that has always annoyed me about the canon high iso shots is shadow noise. I always see huge patterns in the shadow area which annoy the heck out of me. The 645D doesn't show anything like this but it is slightly noiser at the same iso. This isn't really a huge deal unless you plan to print really large...and even then it will look good from a normal viewing distance (same with canon)

Amazing shots. K-5 can't do that I think.

I just got my 45-85mm fa, for landscape work good up to 65mm,
Then corners start getting soft. I did my test at f11, shot the lens at 45,55,65,75,85 using af almost at infinity.
I was pleased because it smoked my 45mm fa, nothing wrong with the 45mm if your not to concerned about corners

So you would prefer the FA 75 over the 45-85 at 75mm? (As would be the default expectation).
