hi gang made the hard decision last night to move back to canon ,i have struggled to get decent pics since buying the d7100 ,there is something not right about the raw files i cannot define it exactly but its like theres a infinity limit on the pics anything taken at infinity is out of focus tried all sorts with the lens and t.c combos but nothing worked ,when my second body decided to play up the other day it was the final straw .i have today returned the camera and surprisingly they gave me a full refund with no argument .and am now in the process of starting to e/bay my lenses etc .i will like ian continue to look in keep smiling |

Sorry you have had so much grief with the Nikon 7100. I'd offer you my D300 but I dont think it is really a step forward for you. Hope that the Canon purchase goes smoothly and that you continue to take great bird photos. Do drop in and post even if you are a Canon user. I have a Canon G12 that I use as well for my underwater stuff. |

i took that as read jonathon its a small group on here but helpful ,yes i could have gone back down the d300 route but its not what i wanted .things move on and its was not a lightly taken choice and you never know it may change again |

Of course now you have done that the long awaited D400 will be announced. |

There are adaptors that allow you to use Nikon glass on a Canon. Don't know if autofocus works or how well. I've also had some concerns with infinity focus with my D600. Some seems to be from camera movement even at higher shutter speeds. It doesn't take much with the high pixil density to throw off sharpness a bit. |

I must be missing something cos...Ive never taken a photograph that needed infinity to be in focus anyway? Or do you mean the lens focusing isnt reliable at extreme long distance settings? Sorry if I am being thick. |

i know exactly what he means eric ,till you actually see the files you cant really define it the 7100 did exactly the same ,its not wrong but its definetly not right either .and just one of the little niggles i couldn't put my finger on .once you know its there though it drives you mad |

Can you post a crop of an unacceptable infinity focus...with a canon comparison? I am sort of getting the impression that Nikon pixels are not resolving the 'dithering' (for want of a better term) as well....but I may be way off the mark. |

Eric, I took this shot up a side street while walking through the town of Elora Ontario a few days ago. It was taken with a Nikkor 24-120 f/3,5 on auto focus at 110 mm and 1/350sec. at f/8 with my D600. The church was at infinity. The crop of the steeple shows my infinity focus concern and the same crop after a quick run through with SmartDeblur, a new program I've been trying out. It must be remembered that these concerns are only for large prints or extreme crops, as this technical quality of picture could be easily hung as a Super B 1(3x19 inches) with minimal post processing.

amazing50 wrote:Couldn't get it to take multiple pix Unfortunately it won't.  What aperture and shutter speed were you using? The image appears to have had the EXIF data removed so unfortunately I can't tell for myself. If you had taken that same image with a Nikkor 180mm f2.8 or a Nikkor 105mm f2.5 the image would be very different and we would be discussing how sharp it was. Zoom lenses and ultimate sharpness do not tend to come in the same box. I venture to suggest the sensor can out-resolve your lens. I am assuming it's hand held, the finial on the church has much detail and is against the bright sky. I would say that is as good an image as you can expect under those conditions. The definition of fine, backlit objects is very dependent on aperture and exposure, small changes in aperture make a big difference to the captured image, because the subject/background contrast is extreme. http://www.naturfotograf.com/lens_zoom_01.html#AF24-120 Notice that Bj¸rn's tests were made with a D1X and D1H with no more than 5Mp and DX, I suspect he would need to revise his conclusions for an FX 24Mp camera. If you can get A3 prints which are satisfactory when viewed from 1.5 times the diagonal than I would be very happy, zooming in in the minutia on the screen is pointless unless you intend to make extreme crops or print wall size images. And even then I am sure when viewed from 1.5 times the diagonal it will be tack sharp. |

How far away from you is the church? Whats the detail like in the car (right mid distance next to lamp post) registration plate when similarly cropped? |

I was set at 11 auto focus points locked in the center with center weighted metering of 15. Iso 200 1/350sec f/8 110mm Nikkor 24/120 f/3.5-5.6G with VR on. I think this plate crop is at 100%. I would estimate the distance at about 100 meters to the church. The full pix that I posted had the EXIF data included but SmartDeblur seems to remove it on the crops. Interesting, I just downloaded my pic and it had the EXIF removed. Is this normal or did I slip up? Attachment: MGA_1538 - Plate crop.jpg (Downloaded 50 times) |

Need to take the same picture with camera on a tripod. I dont have that lens but the lens can also make a big difference. I used to be able to hand hold at 1/20 with a 200mm but now it is not the case. Digital is much less tolerant (sharper) than film. At 24MP the camera is much much better than film ever was even Kodachrome 25. |
|||||||||

Next time I'm out that way I'll use a tripod, do the mirror lockup and remote release, and also take my 70-200 2.8 VR Sigma and compare the lenses. |

Given the lens data you posted (Thanks) I feel it simply the sensor out resolving the lens. I don't see camera shake in that image. I will post a JPEG later to see if the forum software strips the EXIF data but the image size data survived?  |

It's the Apple 'Preview' software, a default software bundled with the system. The basic Photoshop Cs5 Camera data EXIF is below for the same image and I will also post the full EXIF from Ps. Attachment: Screen Shot 2013-10-09 at 20.38.24.jpg (Downloaded 57 times) |

Sorry to see you moving on Jeff. Iain is big into birding also and he left Nikon for Canon awhile ago and seems to be happy. May want to give him a pm, he still is a member on this forum. As an aside, I have moved on also but to Fuji. Got a good deal selling all my Nikon kit. I plan to hang around here, if it's ok, just because I like you guys. |

I ended up using the X20 about half the time mainly due to the weather and hiking up the mountains. Fell in love with the camera. I had been on the Fuji forum for over a year and I was pretty impressed with the line up. So, I decided to buy a X-Pro1 and the 18-55mm lens. Got it and really liked the camera, quirks and all. Ordered the 55-200mm lens and am waiting for the 23mm to come out. I like the weight of the kit. I can carry the X-pro1 with 18-55 attached and in a small bag carry the 55-200 and or the 23mm if I want both. My wife really likes the new kit, she says she is not nearly as worn out after carrying my kit around all day on trips. So, it's a win/win. My photography is travel, landscapes, family, and street. the Fuji does very well. I just don't need the Nikon anymore. It has been fun learning the X-Pro1 and I find myself slowing down and really thinking about what I am doing more now. I feel like I have my Nikon FM back only in digital. It does so many things well I can deal with the few quirks. I don't need super fast auto focus and burst speed. |

The Canon is only a G12 but it gives good results underwater. What software are you using for the Fujis, Gary ? I guess you shoot RAW with the XPro1. No problem using non-Nikon kit and living here! |

So I didn't get to use it too many times. (neve took a single IR shot!) Hope to start again with it in earnest in Italy next May. Theres no doubt of the image quality. It just the speed of operation and battery life that currently let Fuji cameras down at the moment. It will be interesting to see what the next generation of Fujis achieve in these areas. My Nikon bodies may well be relegated to use with long telephotos only! |

We all have different styles and shooting styles. I am just thankful we have so many systems to choose from. I really like the OVF of the X-Pro and the information it can provide and that's the reason I went with it over the XE1. I am sure you will come to like the XE1 for travel. People don't pay any attention to me and the Fuji but when I pulled out the Nikon I was immediately visible. |

That is a very good article and really emphasises the point that you need to focus at or around the area you want sharp and then adjust accordingly. Rather than fixing focus and assuming everything is in focus between two points. This technique is used in street photography for grab shots. They are in focus but not sharply focused!! |

I've been doing this unwittingly for sometime. I use to do the '1/3 in' routine but noticed the rear elements were not always perfect. I especially found this with long machinery when close up. But I guess it's more applicable to landscapes. |

It's a bit beyond my level, I tend to do the 1/3 in and make a judgement on what aperture is necessary. One thing I have being doing more of recently with portraits of two people together is (if I can) to try and get them level to the camera. If not I have noticed that getting the eyes of the subject that is slightly forward sharp makes a better image than the rear, subconsciously when photographing two people I know I was always focusing on my favourite of the two until recently. I have also begun to wonder recently how it is that some people have faces that autofocus just snaps sharply on and others don't. My sister has a son (three) and a daughter (two), Autofocus is spot on every time with the daughter but really struggles with her son. It's not just my photos this effects, it is apparent in a lot of photos the family have taken. |

First thought would be a more uniform skin complexion, but the shape of the face can influence the way ambient reflects, reducing contrast. |
