This question is for current and former Nikon entry level model users. Have you ever had trouble outdoors in bright light reading the exposure meter and settings in the optical viewfinder? It can be so hard to read at times, even when wearing a hat, that I sometimes have to use an auto setting and just hope. The higher end models probably have a brighter readout in the OVF, but after having used a Fujifilm X-S1 with a very impressive EVF prior to the D3300 (chosen because I still have very old NIKKORs) I am considering the X-T[nn] line or X-H1 with IBIS over the D750, not for IQ although either route would be an upgrade, but just to be able to shoot outdoors more easily. Anyone else had this issue? Is the D750 easier to read in bright light? I have not tried a X-T10, etc. but if the EVF is anywhere as good as the X-S1, that might do it even if it isn’t FF like the D750. For other reasons I am not interested in Canon, Sony, Pentax, or M4/3, all great but not on the list right now.

The evf on the Fujis is the whole reason to get one. I have used Nikons since the late 70's. and an exposure mistake was expensive shooting color film. The EVF changes all that. You can always know what your finished image will look like because you are seeing exactly what the sensor is seeing. This is NOT the case with the prism/mirror!

Most of us have either experienced or at least seen the effects of shooting a person too close and too wide. The results are terrible, with the wide nose and odd shaped cheek bones.

I've recently started shooting a Canon crop body camera and I am wondering if the distortion is less than it is with a full frame?

Lens opening / Crop Body Equivalent
16mm -------/ -----25.6
24mm ------ / ------38.4
35mm ----- / ------56
50mm ----- / ------80

If I had a full frame and a crop body both, I could test this myself, but since I don't, I'm reaching our for thoughts??

Thanks!

On a crop body, the virtual focal length is not as wide as on a full frame. An F2 lens will give you the angle of a 2.8. Assuming you are using a lens manufactured for FF, the distortion will be less as well, since distortion is usually max at the edges and a crop sensor is cropping those off.

In the attached image you can see what appears to be lint in the image in the upper left portion in the sky. I've been mirrorless cameras for over a year now and have noticed that the sensor is very hard to keep clean. I preformed a test using 2 mirrorless cameras and 2 cameras with mirrors. The camera specs were very similar, full frame with the same native resolutions. Each camera used a 300mm telephoto lens. Each camera was set up with aperture priority and an ISO of 400. The dust became noticeable at f-stops f16 and smaller on the mirrorless camera (f-16 thru f-32). The smaller the stop the more noticeable. The mirrored camera were free of any noticeable aberrations. Each lens was cleaned prior to the testing. The mirrorless camera sensors were cleaned according to the manufacturer instructions and then manually cleaned. All the cleaning did was move the aberrations around or even create new ones. Does the mirror protect the sensor in cameras with mirrors? Does the sensor in mirrorless cameras attract dust because of an electrical charge? Has anybody else noticed this issue on their mirrorless cameras? It is usually most noticeable in clear blue sky like the attachment.

Another thought. Are you using mainly long throw zoom lenses? They suck in air as the barrel extends. With the air comes anything in it. Apparently Sony bodies are especially leaky - something I did not know, as I have never owned one. My Fujis seem to be quite tight, and no dirt problems so long as care is taken changing lenses

Artifacts caused by any lint in the system might be more noticable because of diffraction. I have been using Fuji mirrorless cameras for several years now and have never noticed any of the problems you are describing. But then, I have never used F16 and above. If anything I would expect the mirrored systems to be dirtier because of the mirror slapping around next to the sensor. If you take care in changing lenses, there should be no debris problem with a mirrorless which provides lens cleaning on both on and off. I suspect your problem has much to do with the technique of lens changing and your environment. Also the artifacts in the sample image appear to be out of focus and I would suspect they are in or on your lens rather than on the sensor.

Hi. I have a Nikon D7100 and would like to photograph the night sky. I have a tripod and a remote, but I could use some suggestions for a wide angle lens. I have looked at some of the Sigma, Tamron. Unfortunately, I am unable to afford a Nikon lens. I even thought of upgrading my camera to a D750, but I still would need to purchase a lens. Thankfully, I have until the summer to purchase and become adept at using this. Any suggestions would be most appreciated. Thanks.


Look at the Rokinon 14mm F2.8 and look up some of the reviews. One person who does a lot of astrophotography highly recommends it. I have the 12mm which they only make for mirrorless, but it is comparable in quality and IQ. https://www.lonelyspeck.com/rokinon-14mm-f2-8-review/

I would appreciate it, if any of you have used software to removed unwanted objects or people from a photo. I would seldom want to use it, but I have this lovely photo of my granddaughter (6th grade), that is doing hurdles for the first time. I do have Photoshop Elements, but I haven't learned how to do layers, and I don't even know if that would do the job. I am planning on attaching a file of one of the photos I am interested in removing people from. The girl in blue is my granddaughter. Thank you kindly for any suggestions.

Well, is it the manual dials on the visceral Fuji XT3 challenging or do you prefer menu systems, or...? I use both FF Nikon D800 and Fuji XT3 & XF100. I prefer the Fuji gear for the following:

Size, weight, visceral manual controls that are also confirmed in the fabulous EV, the film-like colour options, it’s ability to make people look soooo good (colour), pricing, absolutely pristine lens options, flash options combined with leaf shutter, and on & on. Yes, my tank is Nikon gear is wonderful in its own right, just not wonderful enough to make the grab when I head out the door 95% of the time.

If you don’t prefer your Fuji gear, there is a well-established second-hand Fuji market out there.

Cheers!

You are right on target. I had both Nikon and Fuji for several years, but the Nikon was acquiring a layer of dust! So I gave it away.

Friends... I'm an avid 75-year-old enthusiast, not interested in highly technical answers to this. I love shooting with my Nikon d7200, but got caught up in Fuji world. I have no trouble with my Nikon, but find Fuji a bit difficult to use. I know I know, stick with the one I love, but I do like the size of the Fuji stuff (xT3 & x100f). Your thoughts?


What do you find difficult about the Fuji? I find it much EASIER to use. I gave my Nikon 5500 away because every time I wanted to change a setting, I had to go to the menu or the touchscreen and fiddle with them. With Fuji i turned a dial ISO was on the left, shutter and comp on the right, and the aperture on the lens. Direct real manual control of the exposure triad. Focusing aid of the blue outline gives you simple manual focus if you turn off AF. Or you can turn everything to auto and have a point and shoot. What could be simpler?

If you really think about it color is made of noise, nothing else.

The amount of luminosity between adjacent pixels is what creates the appearance of noise.

Trying to remove noise essentially kills the color, especially if one uses commercial products that are heavy handed in their 'noise correction' (read indiscriminate blur).

You are much better off using a light surface blur then a Gaussian blur with a layer mask to achieve the same effect w/o getting muddy results.


If this is an attempted cure for boredom, try again.

Why do these marking seem to be missing on most?


The only lenses where hyperfocal markings would be useful are wide angle primes. Both my wide angle primes have hyperfocal markings on them.

Up to a point, you are correct, but if you tilt a camera up, having the sensor not perpendicular to gravity does create 'unnatural' view that the brain rebels against, and this effect is more evident as the view becomes wider. For example, both views below were taken last Spring at 10mm with my Pentax KP. In both views I held the camera over my head, but the second one, the one I actually used by cropping out much of the street, all buildings appear to be basically parallel, as they actually are - the first one, tilted up it turns out, the leftmost and rightmost buildings look unnaturally tilting towards each other..

I see curvature on the lower photo - barrel distortion = much more disconcerting than tilting of straight verticals. The really strange effect of camera angle of elevation with wide angle lenses, as in your upper photo are obvious. And incidentally, the EVF of the mirrorless cameras show you that effect much better than the optical viewfinders do. - Another bonus of mirrorless.

Ok... So this IS a perspective issue ( I said earlier is was not, without a sample)(keystoning), caused by the camera/lens pointing up or down slightly. Sensor is not perfectly parallel to subject. It can be corrected in light room.

One way to minimise this is using a tripod, and make sure it is level in both directions, and use a nodal rail.

Why is keystoning so undesirable? The eye sees it that way, otherwise we would not have depth perception. It is natural. To have parallel lines looking up is unnatural. Parallels visually converge with distance. Why would you want an unnatural effect in a photo?

Which lens profile did you use? This is quite good, distortion-wise.


No "lens profile". Just stuck it on my Fuji and popped the shot of my livingroom. I don't think you will find a $300 F2.0 12 mm lens with less distortion than this one. I think it is a good lens for indoor architecture and certainly for landscapes.

An inexpensive alternative is the 14mm Rokinon 2.8 which is small and compact and very sharp. If you have a mirrorless, the 12mm f2.0 is available - even faster and smaller. Very sharp. One test showed it was sharper than the Ziess. It is manual focus, but at 12 mm you just set it hyperfocal and forget it.


And here is a quick shot taken with the 12 mm, at F2. focused hyperfocal. (Worst possible way) Note the distortion (Not much).

I use NISI filters on many occasions and want a bit more ease attaching the filter system. I've had my eye on the Nikon 16-35mm f4 and the prime 20mm f1.8 but I would love your advice on a wide angle you use that I haven't researched or if I'm on the right track with one of these two lenses. Thank you in advance.
