Pentax F* vs DA* 300mm

Hello all, first post.

I recently began making my way back into photography. I take a lot of boat/marine related pictures and some are sold to boating magazines. I work as a yacht captain but also do some freelance writing for a handful of sailing mags.

Just switched from Cannon to Pentax. Drawn over by the weather sealing. Bought a K50 and a DA* 16-50. I love the 16-50.

Looking for a telephoto, I have come across an F* 300. How does this compare to the DA* 300? Looks like they would be equal money.

Any help would be most appreciated!

Thanks!

Image quality wise the two are very close, but the F* is not weather sealed, so you may want to go for the DA*. Another excellent and more versatile option is the DA* 60-250mm F4 zoom.

And welcome to the forum! I'd love to see your boating images!

Ole, thanks! I started this mission looking for a good used 60-250. Maybe I should complete the circle and return to that thought. The F* was a curiosity - and still is. However, the weather sealing might "seal" the deal...

Welcome to the Forums. I cannot afford a 300 F or DA* but the F was built for full frame coverage while the DA* is supposed to be for APS-C. Both are highly thought of. Check them out in the lens reviews.

The F is an extremely nicely built lens....

Both are excellent lenses, however the F commands a premium price because it is starting to move into the collector status. Optically both are very good, however the DA has quick shift, is weather sealed, has silent SDM focusing, and modern coatings. The F was designed for film cameras.

If you like collecting old glass get the F, if you just want to take pictures get the DA.

At the end of the day, with an APS-C sensor, will the DA provide better results? I must admit, I find the classic glass alluring. If only there was a money tree...

There have been several threads in the past asking about the difference between F, FA and DA 300mm lenses. I don't believe I saw in any of those threads a definitive answer to whether any of them were any better optically. They are all excellent and picking one over the others for image quality is simply nit picking. Features on the other hand do differ. I think the DA has better features, with the F second and the FA last. In short the only thing the F has over the DA is that it is classic glass. For your application, near water, I think the DA is the better choice.

Welcome. In your situation with potential for lots of spray, you would benefit greatly form the DA*300. The 60-250 would also be useful with some zoom. Yachts are after all not that small.
I shot some dinghy endurance sailing and the DA*300 was great for capturing crew closeups.

HI SaltyPentax,

Welcome to the forum.

I think for your needs, the WR of the DA* trumps anything the older lenses might offer. I don't think there is any feature that could be more important for your situation. I believe that the DA* also has a more durable coating on the front element, but I'm not sure. . .

FYI, the F* and FA* have advantages for less demanding conditions -- they're compatible with third party TCs because the use screw drive for the AF. The good ones (Tamron/Kenko and Sigma --maybe Vivitar) are about equal in IQ and less than 1/3 the price of the new Pentax 1.4x AW that is the only TC that will AF satisfactorily with the SDM focusing of the DA* 300 or 60-250. The new Pentax TC is a good one, but pricey at $600. Also, they're physically smaller and lighter (67mm front element vs 77mm) but of course, they're also 1.3 stop slower at max aperture.

From a quick side by side comparison when the DA* was introduced, The DA* is a tad sharper wide open, but that was the only difference I saw. I chose to stick with my FA* 300/4.5, but I know of others who chose to upgrade to the DA*.

The difference in maximum aperture is actually about one-quarter of a stop, not 1.3.
While I agree that the WR of the DA*300 may be the deciding factor for your purposes, I chose the F*300 over it, because the F* is lighter (190g is a significant difference), smaller and has a substantial detachable tripod foot.

Makes sense regarding the weather sealing. Love the look of the F*. It will be a hard lens to forget about... If money were not part of the equation (which it is), do you think the 60-250 alone or the 50-135 plus either the 200 or 300 DA*? I keep reading all of these glowing reviews of the 50-135, and I am tempted (even low-balled a few on e-bay). I know the reach won't be enough come summer, but if I can manage two lenses (fearful my wife might think I have a new addiction)... Anyway, the 50-135 and 60-250 appear to have a lot of overlap, but maybe not considering the speed difference. Would that be crazy? I know this is a horse that really has been beaten... And the obvious one lens choice would appear to be the 60-250... Sorry to be ramble. And then there is the altogether sensible Tamron 70-200 2.8... Easy on the wallet...

A really fast lens and shallow DOF don't seem to be high on your needs list. You already have the DA*16-50. It would seem logical that the DA*60-250 would be worth 2 lenses in one compared to 50-135 + 200/300, and you only miss a small amount of FL range. Get a second WR body and don't need to change on the water. My 2cents worth

In your shoes, I would go for the 60-250 right now. That was my progression. Bought the 16-50 then 50-135, sold it and bought the 60-250. Then bought a DA300. After the grand kids started having school activities and such, I repurchased the 50-135. It is still my least used of the 4 DA* lenses that I have but It takes great pictures.

Sound logic. The 60-250 will be a very useful lens. The hunt is on. Still might pursue the F 300, just because it is so beautiful, but for the daily bread and butter, no doubt 60-250 will do nicely.

Thank you all for your help and guidance. This forum is a truly great asset and it makes me proud to be a Pentax user. My first real camera was a k1000 and I'm very happy to be back in the fold.

Happy picture taking!
