Pentax Q7 and 300mm lens - amazing!

.
.
I know, I'm late to the Pentax Q club. Got my Q7 a few weeks ago.

Today I finally hooked up my Nikkor 300mm f/4 lens to it. Shot a pickup truck that was about 60 yards away.

Here's a 100% blow up of one of the truck's tires.

You know how when you buy a brand new tire, it sometimes has those tiny, pin-like pieces of rubber sticking out from the sidewall? Well, the truck tire that I photographed must have been fairly new because in the 100% blow up I can clearly see these little pin-like rubber projections from the side wall. WOW!

I can't wait for spring to come and the return of the migratory waterfowl. I expect to get some great closeups with this set up. Great thing is I'll be so far away I'll be able to capture lots of candid bird photos without disturbing them.

Try a Q10 with 1000mm, pretty difficult to handhold!


Theres some stunning images shot with the DA 300mm.

It's even better for macro than for telephoto.

Would you say its easier to do macro with this than APSC or FF? The DOF is a real pain .

Most of the time I don't even try to hand-hold my Q-7 with 200mm; for one thing, keeping consistent aim from first framing to focusing to shooting is very hard {that's why I have a monopod}

Me too, but I left it at home that day....went and swapped to M135 which works great on Qs, had to move a bit closer though.

Because of the crop factor, the DOF at an identical f-stop is much deeper for an equivalent framing , which does help things, and the subject distance is greater to boot. The spider image above was hand-held using an FA 50 on an adapter in natural light.

What an image. Wow. Was it the FA macro or standard FA 1.4 or 1.7 lens?

The macro 50mm f/2.8 on a Fotodiox (shutterless) adapter.

I was thinking the DOF would be a big help there. Do you bother doing macro with your K3 or K1 after using the Q?

Well, most macro I do is handheld with flash, and I don't have the Pentax K-Q shuttered adapter, so I'm stuck with 1/13 sync on the Q for the moment. I've actually been looking for a good deal on the adapter to see what it's capable of doing on such a rig. I'm shooting mostly K-1 but will bring the Q with me (usually with a Bolex Macro Switar or Kodak Ektar attached) with me when I want something pocketable for casual snaps or opportunistic macros. Because they are much smaller lenses, they don't give the DOF/distance advantages of the adapted K lenses, but they are very small and behave similarly to how the larger macros do on the SLR bodies.

A couple macro examples with a 12.5mm Switar:




And the Kodak Cine Ektar 25mm:

I really like your images. Thank you for sharing. Thank you also for explaining some of how you do things. Yeah I've tried my hand at macro on the F100, DA 35 ltd, etc on the K1 and k3. I've tried extension tubes as well. Perhaps my technique is bad, but I recall getting more keepers with an old point and shoot because of the DOF . IT doesn't seem to matter even when I use F32. Perhaps I need to learn to focus stack, but with moving things thats nor really an option. Even berries in a breeze proves challenging.

Don't forget to try some night shots with it. You can expect to get images like this.

Here is a test shot of a blue surgical cotton towel I did a couple years ago to see 1:1 with the Q7.
While the subject matter is not particularly inspiring, it does show what you can get. This was
with a cheap generic Fotodiox K-Q adapter. I imagine that the image would be sharper with the
Pentax adapter and a diffused flash. DOF is pretty shallow!

The first image is of the Q7 full size image resized to 800x600 pixels. The second is a actual
pixel crop of the original image.

Others are saying that the "Q" family was a mistake from the beginning, but I'm glad Pentax did make the Q-7, because I purchased mine specifically for this application. I'm using a 70-300mm Sigma K-mount lens on my Q-7 to provide the best birding kit I've ever had.
