Hi everyone.
The light was much better today so I took some better photographs with my Optio W90. I don't think it's often that one of us can get our hands on these 2 lenses at the same time so I thought additional pictures will interesting before I try to sell the A*300mm/f2.8. The little lens in the middle is a Pentax A50mm/f1.7 that I show to give a sense of scale.
Some observations about the 2 lenses from me.
1)
Ergnomics. Good handling is a big plus with me and both these lenses have good ergnomics (exception is hood of FA*, see comment below). The FA*300/2.8 has a clutch for AF/MF, which is very handy.
The tripod mounts are decently sized and work well. They could be a bit bigger, but that's just my personal preference since most of my work is done on tripods. (I love the tripod mount of the F*300mm/f4.5!).
The built-in sliding hood on the A*300 is a pleasure to use, it is fast, easy & effective. The bayonet hood of the FA*300 is difficult and clumsy to use, and I seem to be fighting it all the time when mounting it and reverse-mounting for storage.
The filter drawers for both lenses are located in the back. I've had this drawer come loose on the FA*300 once already but it has never happened on the A*300.
2)
Focusing. I've read how people prefer the autofocus feature of the 300mm/f2.8 lenses. I disagree and I do not think these opinions are from people who have actually used the A*300/2.8 lens for any length of time. Manual focus with the A*300 is very easy because the long focal length (300mm) + large f2.8 aperture means that in-focus subjects just "snap" into place. The focusing ring is smooth and easy to operate with a couple of fingers. It will not take you much practice before your manual focus technique is as fast as autofocus.
3)
Autofocus speed of FA*300/2.8. The autofocus speed is actually pretty quick. No complaints from me. With respect to point #2 above, can I manually focus with the A*300 as quickly as the FA*300 can autofocus? Answer: yes, probably.
4)
Exterior Finish. The FA* has the typical silver coating of this series lenses, which is more prone to cosmetic scuffs & scratches. The A* has the more durable white coating of this series.
5)
Best IQ. Which is the better lens for image quality? If you read my previous lens reviews you will know I don't pixel peep or take lots of test photos of charts and walls. I think from normal, everyday usage both will give equal quality images, meaning they will have the classic
* ["star" lens] Pentax look: needle-sharp images, jaw-dropping colors and great contrast, excellent bokeh, outstanding image resolution.
The person who sold me the A*300/2.8 bluntly stated it was sharper and gave better IQ than his top-end Nikon glass, and his Nikon lenses were the best as he was a working professional.
I do note that when the A*300/2.8 and the FA*300/2.8 were both available for sale at the same time the A*300 cost much more, so maybe this also tells you something about which is the better lens. But you simply can not go wrong with either one.
These opinions are my own. Your mileage can and will differ. Enjoy!
