I was just reading a lens review and it talked about the LATERAL (or transverse) and the LONGITUDINAL chromatic aberration. I know what CA looks like but couldn't name/identify different types. Here is a good explanation.

As posted last week, my wife and I picked up a couple of Tamron 150-600 lenses. This weekend we got out and took some pictures to see how they perform on our D7100s (I'll try the D800 next time). The assessment so far is that they seem to perform very well, with both producing very similar...

I've previously posted about people complaining that relatively light setups are too heavy to use and while I accept that some people may have medical reasons for finding this a problem, others are probably just wimps. Yesterday we went to the zoo to try the 150-600s on some captive subjects...

Over the last couple of years many have posted about the D800 needing a tripod for sharp images because of the 36mp resolution. I recently did a 3 week trip to the states and took a 30lb bag of gear plus a tripod. Very quickly I decided I was on holiday to visit and see places where I would...

I've had one of these 150-600 lenses in mind since they were announced but I wasn't in a mad rush to get one and certainly didn't want to be in the first batch. So far in the UK they have been order only on a lengthy lead time so I couldn't get one if I tried. Today I was just curious if things...

Last night we stayed in Bishop CA on our way to Yosemite. We went to a Denny's for something to eat. In the US and several European countries , unlike the UK it is common to leave cash tips on the table or bar. In the UK you normally hand over cash or add it to the bill. So when I got up to pay...

As part of our US holiday we hired an RV for the first week. It was only a 25' standard class and I think I would get a 32' next time as the layout is much better. In the Uk a normal car licence allows you to drive up to a weight of either 7700lb or 16500lb depending on when you obtained it. For...

I was at Hoover Dam yesterday as part of our holiday. We are actually in Vegas for three days but we are leaving a day early as I really don't like the place as much as when we came ten years ago. But back to my story. I had my D800 and 16-35 F4 on my Black Rapid strap as I walked around the...

We are visiting Monterey in a few weeks and plan to take a whale watching trip to see humpbacks. Has anybody done a similar trip and if so what lenses did you use? I'm thinking 70-200 on the 7100 for reach and 24-120 on the 800 if they come close. Any other tips for shooting whales. Sent from...

I picked one of these up yesterday for use on a D7100 and noticed two issues. It appears to force the image review timer to be 1 minute. It also changes the image review to function differently. If you have it set to press the OK key to zoom in, it no longer scrolls around by holding the rocker...

Having been a big fan of the 18-200 for many years my better half has recently started saying how much better the images from her 35mm 1.8g and 70-200 2.8 are by comparison. Specifically the sharpness. If the light is bright I find the 18-200 does a great job for such a versatile lens, but it...

We are travelling to the US in just under three weeks visiting Salt Lake City, Bryce Canyon, Vegas, Death Valley, Yosemite, Monterey and San Francisco. Unfortunately I'm still pondering what to take. My paranoia even starts with my bag which is a Lowepro Vertex AW300 rucksack which I purchased...

I was just looking at a yet another post (Not on this forum obviously) where somebody was complaining about the weight of their gear. This guy had a D7000 plus 18-105, 70-210F4, 35 1.8 and 50 1.8 lenses. The 7000, 7100 and 610 bodies are hardly heavy given the level of performance they offer and...

A common thing I see written about the D800 or even the D7100 for that matter is "what's the point in all those pixels". In truth I very rarely need them myself as I don't print big, however they are very useful to me for the following reasons. If I ever do manage to take a great image and...

I submitted this image to an online competition recently and one of the comments was "your sensor needs a good clean". Having looked again I can see a spot on the left hand side but apart from that it looks pretty clean to my eyes. This is also a much higher resolution image than the one being...

Coming from the D70 and then D300s cameras I've historically viewed anything above ISO 1600 ans something only suitable for the brave. When I got the D800 and D7100 bodies I started to realise that the sensor technology had moved along such that 6400 was very useable, certainly on the D800, with...

I currently have the full creative cloud but I reckon I really only need the Photoshop/Lightroom version. I currently have the cloud through the education program so I only pay half price and the access it gives is great if you need it, I just think I could save £15 per month if I take the other...

I was out for a walk last night and snapped this Robin. It was too far away and I think I needed more the 1/1000 for handheld at that distance, however I decided to have a little play with it in Photoshop CC. Now this picture will never win any competitions so please don't judge me by it, but I...

My wife and I each have a PC with Lightroom 5.x and Photoshop CC installed. Mine has 8GB and hers has 4GB. She has been complaining that Photoshop has been running slowly, especially running Nik plugins (60+ secs to load). I went through a process of ripping all the junk off the PC to make the...

If you really need one of these to stop you breaking your camera you really should take up another hobby. See the video here: https://www.youtube.com/watch?list=UUNjL-dOaBmfnwaXoGCLe_UQ&v=4jtsepK_vew&feature=player_em bedded.
