Cool, figured. Do you get to use the shoe on the transmitter when it's acting as the master controller on the body? I don't know if people do that often enough for Cactus to have bothered with that functionality.

Would it be correct to assume you can plop one on the body as the transmitter, and then use the other three as receivers for your three off-camera flashes? And since I'm fairly new to flash photography and not familiar with the gear, do you also get to have a fourth on the body, as well, if you wanted it?

It's insane that you haven't sold this by now. Bought my screwdrive-only a few months ago and am super happy with it. Screw AF is just as good as any other non-SDM lens, and manual focusing with this this lens is more of a pleasure than probably any other lens I own.

I'll play around with that and see if that correlates with the metering. Thanks!

I would think you could get away with that if it's something minimal (tape?) because there's really nothing there to interfere with the aperture lever except the inside of the adapter. I'd be more concerned with the object leaving a residue on the lever.

Aperture lever formula
Posted By disord3r

This question relates more to the mount than any specific DSLR, and relates to the aperture lever.

Is there a formula that I can use for approximating the f number of a given lens based on how far the aperture lever is moved? Different lenses have different minimum and maximum ratios, so that would obviously have to factor in the formula, but I'm attempting to the approximate the f number based on a percentage. For example, if I have an adapter which has aperture control, the movement of the adapter's aperture ring is considerably small. If I move it, say, 50% of the way, I want to be able to guestimate what the f number is for a lens that has a maximum of 1.4 and minimum of 22, a maximum of 2 and a minmum of 22, etc. It's not going to be the same for both but I know the number is not linear.

Does such a formula exist, or is there a better rule of thumb to use? I realize this is fairly inconsequential since the body will still meter properly.

Semi on topic (q adapter, tripod mounts)...

I use the Fotodiox PK(A)-P/Q. It's the one with aperture control, but doesn't have a tripod mount. All of the quick release plates I have for the 1/4" thread will interfere with the adapter. Is there an easy solution to overcome this via specific plates or spacers (a la Nikon TA-N100)?

What's the stigma? I've always heard this is a great lens, particularly good for video. I've decided that if I ever need to fill this focal length I'd just go for the HD 20-40 despite it not being nearly as fast, but I've never heard anyone say anything rough about this lens.

For Sale - Sold: "Nikon K3" Split focusing screen for K-3, K-3II, K-5 etc. (from focusingscreen.com)

Recently, mine transferred perfectly from my K-50 to my K-3. Someone else has mentioned moving theirs from a K-30 to K-3. I made a post about doing so before I actually made the move, and it was claimed that it should work in K-7, K-5, K-5II, K-5IIs, K-3, K-3II, K-30, K-50, K-500, K-S1, K-S2, and K-70. Based on the successful moves mentioned here, I have no reason to doubt that list.

Mine made manual focusing so much easier. I find it a pain with the focus peaking on the display, but it's so quick in the viewfinder with the split prism. It doesn't interfere at all with normal focusing and doesn't seem to affect my view in the viewfinder except when I'm shooting with aperture rings around f11 and beyond. I don't do low light shooting, so it's all good for me. I wish I had done it sooner.

By the by, for anyone who should happen to buy this - that little plastic gripper is excellent for delicately placing the screen into the empty screen tray above the mirror, but not so good at getting the stock screen out. Be suuuuuuuper careful - I used some metal tweezers, and I'm surprised at how easily I etched the little handling tab.

What size for memory card(s)?

I'll be recommending 64GB cards or twin 32GB for 24MP to anyone who asks.

I just upgraded from K-50 to K-3, and I always shoot in RAW+. When I started to play with the settings and made the switch to RAW+ on the new body, I noticed that this only allows just shy of 500 snaps on my 32GB card. It was waaaaaay more than that on my K-50. One of my more recent outings resulted in 702 snaps on my K-50, so I know that I will never be comfortable with only 32GB in the camera anymore.

what lenses to pair with the K-3ii on a budget?

My vote would be the 18-135 zoom for a start. It's cheap enough and covers enough focal length that you should be able to make do with it for quite a while. I'd intentionally hold off on buying any other lenses and just force yourself to discover the ways you find that lens lacking, and resolve those shortcomings by adding what you lack. A faster zoom, a couple primes to suit certain types of shooting, etc.

The alternative is to buy lenses and find out you didn't need them and put yourself through the hassle of returns or the loss of money on resale.

It's possible that the important weather sealing actually takes place on the bottom where the knob meets the body, but without seeing the knob removed it's hard to know for sure. If there's evidence of weather sealing on the button atop the knob as well, then you may have a problem.

For some reason, I'm only satisfied with this and the 50/1.8 on longer exposures. Past about 1.5s, the sharpness is amazing closed down a few stops. But even just handheld sub-100th f/8 shots on bright sunny days are never especially outstanding on my camera.

If the "tidying up" part referred to potentially making a nature scene look less natural than it would have been without such tidying up, I have the same view when it comes to post-processing beyond simple sharpening and color correction. Nothing wrong with wanting your shots to look as good as they can be.

On aperture equivalence: are FF lenses on crop bodies a bad idea?

this has nothing to do with focal length equivalence between sensors

I have a K-50. When Ricoh/Pentax announced the FF body, I was stoked. When I got wind of the pricing, I was super stoked. In anticipation of eventually buying a K1, I decided that I ought to focus any lens purchases on lenses that would be compatible with the FF body, whether designed for film or digital. I have read, however, that this may be a bad idea for crop bodies.

Lenses, whether FF or not, make the amount of light gathered available to an imaging circle that is designed to be more or less the same size as the sensor's diagonal. But the aperture values should be considered with respect to the sensor size it was designed for, no? If I'm using a FF lens on a crop body, of course I have to take the focal length equivalence into account so I know the angle of view I'm getting, but in addition to cropping out pixels that the crop sensor will see, I'm also cropping out light. I therefore should have to apply an equivalence to the aperture value as well, correct? A FF lens that is f/2.8 may be so on a FF body, but on a crop body, not all of that light is reaching the sensor.

I'm prepared to deal with this for the time being, but what does this mean for DA lenses like the 50 1.8 or 35 2.4 which are apparently designed for a FF-ish imaging circle? Does that mean that they aren't really functioning at their stated aperture value at all when mounted on a crop body? They gather the same amount of external no matter the body they are attached to, but whether the sensor is able to use that light is a different story. The aperture value will be read by a crop body as 1.8 or 2.4 respectively, but how does the body deal with that? Does it not care, and just meter the light off the sensor? What is is even using those values for if not for some sort of calculation?

3. Mounts are replaceable, no? If you have a donor, it seems like a minor hassle and might be a good way to turn an otherwise perfect lens into a killer deal.

The only problem with rechargeables is that the voltage starts out low compared to akaline batteries (1.2v vs. 1.5v). I find that with my Amazon basics the voltage drops slower over time as compared to traditional batteries so I still get a good amount of life out of them. But devices can vary in their tolerance for the voltage from the supply, and may decide rather quickly as they discharge that the voltage is too low to work. If the device is designed to work with lithium ion rechargables, then it should already be tolerant of the low voltage, but not every device is going to play nicely with them. The more cells the device requires, the greater that difference will be (i.e. 6 cells in series is only 7.2v versus 9v from traditional 1.5v cells). If that thing requires 9v and wasn't made to work with rechargables, it probably ain't gonna cut it. I found this out with a battery-powered air mattress pump which requires 8 cells. The lithiums just couldn't produce the voltage, and it wasn't designed to work with rechargables.

For the body itself and the AF200 (4-cell) flash, I haven't noticed a problem; both have lasted multiple outings on a topped-up set of 4 amazon basics each.
